1 TEXT

Command Description

0x40 Set palettes

0x42 Select color to the background palette

0x41 Set the character spacing

0x45 Set/cancel the textbox limitation

0xE0

The configuration display mode: PARA1.2: 0=normal display 1= 90°display PARA2.4(H600 and K600+ only): 0=automatically restore the background when text is displayed 1=display text in accordance with the specific background color

0x53 Display the 8×8 string in ASCII, relating to the 0x00 font.

0x6E Display the 12×12 Chinese string in GBK, relating to the 0x20 font (Chinese) and the 0x00 font (ASCII).

0x54 Display 16×16 Chinese string in GBK, relating to the 0x21 font(Chinese) and the 0x00

(ASCII).

0x6F Display the 24×24 Chinese string in GB2312, relating to the 0x22 font(Chinese) and the

0x00 font (ASCII)

0x55 Display the 32×32 Chinese string in GB2312, relating to the 0x23 font(Chinese) and the

0x00 font (ASCII)

0x98 Display any dot matrix and any encoding string, relating to the custom font library. But the 0x00 font is used with ASCII on the GB2312 and GBK mode

0x9C Cut icon from the specific picture and the background of picture is automatically filtered out. Automatically restore the current background before paste

0x9D Cut icon from the specific picture and the background of picture is automatically filtered out.

0xC108 Parameters are identified and displayed automatically based on parameters displaying in temporary buffer

1.1 Display Text in Programs Directly (C & ASM51) C language:

uchar *HZSTR="汉字显示OK"; //The Chinese string uint x, y, color; prints (0x54, x, y, HZSTR) //The 16 dots matrix (GBK Chinese string) display, (x,y) is the

//coordinates. It can also be written as:

prints (0x54, x, y," 汉字显示OK") ASM51

HZSTR: DB "汉字显示测试OK", 0xFE ; The 0xFE is the end of string MOV DPTR, #HZSTR LCALL TXROMS

Note: In Chinese GBK code operating system, C or ASM complier will translate “汉字显示测试OK”(A Chinese string) to GBK code automatically. The Chinese GBK encoding (Extended character) is downward compatible with GB2312 (Primary, secondary fonts).



1.2 Textbox Format Control The procedures of effects shown as the right picture: Use the 0x41 command to set character spacing: dx=0 dy=12 Use the 0x45 command to set textbox on (Xs,Ys) (Xe,Ye). Use the 0x98 command to display text Use the 0x0D and 0x0A commands to control the linefeed. C_Mode.6=0 means the background color does not displayed.

1.3 Automatically Adjust ASCII Characters Spacing Each character in dot matrix font has fixed a size. So the ASCII characters such as “i”, “l” and “.” will be displayed a bit loose. Users can use the 0x98 command and set C_Mode.4=1 to solve this problem. Take the WiFi as an example: When C_Mode.4=0, “W I F I” is displayed; When C_Mode.4=1, “WiFi” is displayed. When C_Mode.4=1, Characters must be 8-bit encoding and the downloaded fonts need to rotated 90° (TS3, Portrait mode 1).

1.4 Display Text Without Its Background

Procedure to make the textbox of a solid color background: Select the background color on (x-1, y) with the 0x42 command. Display the text. Please set: The background color and foreground color are both displayed. Advantages: The previous data will be automatically covered when refreshing data because the background color and foreground color are both displayed.



Procedure to make the textbox of non-solid color (Pictures) background: Method 1:

Use the 0x71 picture cutting command to recover the background color of textbox display area (The cyan area in the above picture) to erase the previous text display; Use the 0x98 text display command to display. Set the background color of textbox not-display (C_Mode.6=0). Advantages: This method can be applied to overlay text in any picture background. Text display command must be the 0x98 command. Method 2: (H600 and K600+ only).

Use the 0xE0 command to revise Para2.4=0 and recover the background automatically when displaying the text. Use the text display command again and text background will be ignored automatically. Advantages: This method is valid for any text display command. But the background must be the current picture instead of cutting or copying background from other pages.

1.5 WordArt Characters (Special characters) Display

How to display “620” as shown above: Display case one area is on the current picture: Use the 0x9D command to cut and paste the value icon from the icon library on the display area;

LOGOD9D(300,200,6); LOGOD9D(330,200,2); LOGOD9D(360,200,0); void LOGOD9D (uint x, uint y, uchar i) { uint logoxy[]={0,0,40,40,40,0,80,40,80,0,120,40,120,0,160,40,160,0,200,40,

200,0,240,40,240,0,280,40,280,0,320,40,320,0,360,40,360,0,400,40}; //The coordinates of icon uchar j; txword (0xaa9d); txword(50); //The page location where icon has been stored for(j=0;j<4;j++)

{ txword(logoxy[i*4+j];} txxy(x,y); txeof(); // 0xCC 33 C3 3C are the end of string }

Display case two area is not on current picture (such as temporary pop-up warning message box) Use the 0x71 command to restore the display area in order to erase the last contents. Then use the 0x9C command to cut values icon from icon library and paste them into the display area. Piccut (0x71, 7, 0, 0, 90, 30, 300, 200) //Assume background Is an area icon on the 0x07 page LOGOD9C (300, 200, 6); LOGOD9C (330, 200, 2); LOGOD9C (360, 200, 0);

1.6 Vertical Text Display



Use the 0x98 command to set C_Mode.5=1 in order to achieve the vertical text display as shown in the picture above.

1.7 Numerical Parameter Display In many cases, in the users’ program parameters are saved in HEX mode. But it needs to convert into ASCII code when it is displayed: INTDSP(100,200,620); void INTDSP(uint x,uint y,int value) { uint i=10000;

uchar j,k; txword(0xaa98); txxy(x,y); txbye(0x21); //16*16 GBK txword(0xc201); //The foreground color and background color are both displayed //with 16*16 in GBK encoding. txword(0x0000); // The typeface is black txlong(0xffff); //The background is white if(value<0) txbyte("-"); //Display the minus for(j=0;j<5;j++)

{ k=value/i; txbyte(k+0x30); value=value-k*i; i=i/10;} txeof();} //0xCC 33 C3 3C are the end of string.

But it is inconvenient for users to manage the problems such as text alignment and invalid zero shielding. In the case, the 0xC108 command can be applied to solve these problems. Firstly, use the 0xC0 command to write parameters to be displayed in temporary buffer with according format; Then use the 0xC108 command to call parameters. Multiple parameters can be called each time. INTDC108(0x6305,100,200,123450); // Display 123.450 in 16*32 dot matrix. Align right. At the //(100,200) position void INTDC108(unit m,uint x,uint y,long value) { txword(0xaac0); //Firstly, write the temporary buffer

txword(0x0000); //The temporary buffer address txword(m); //Display modes txxy(x,y); txword(0x0000) //The typeface is black txword(0xffff); //The background color is white txlong(value); txeof(); // 0xCC 33 C3 3C are the end of string txbyte(0xaa); txword(0xc108); txword(0x0000); txbyte(0x01); txeof();}



Tips: Users can also use the 0xC108 command to achieve the synchronous display of mass parameters. (If the display command is sent separately by each parameter when many parameters are displayed, communication and data processing will take a lot of time. So it is hard to achieve the synchronous display. The effect of visual parameters will be inconsecutive.)

1.8 Display Rolling Text In some applications, because of the limitation of display area size or aiming to draw, it requires to display rolling text.

The entire text can be seen as a string pointer (Array). In fact, roll means continue to modify the result of the starting position. The horizontally rolling text (Display rolling textbox in single line) is achieved with 0x71 and 0x98 commands together. The process is shown as follows: A. Use 0x71 command to restore the background of display area; B. Use 0x98 command to display the starting text of specific pointer’s position (Note: when C_Mode.6=0, text without background color) C. Modify the pointer’s position. Repeat steps A-C recursively to achieve to display rolling text. If the background of text area is solid color, use the 0x42 command to select color. When using the 0x98 command, if set the background color to display too, it needn’t use the 0x71 command to restore the background and text is displayed very quickly. Similarly, if the textbox limitation is set with the 0x42 command and the textbox can be seen as a “segment” of the text string, you can easily flip up and down rolling easily by modifying the display buffer pointer. void hzroll(uint xs, uint ys, uint xe, uint ye, uchar pos, uchar num, uchar *str) { uchar i,j,k; i=uchar(sizeof(str)); // Find out the pointer tial’s position logod71(0,xs,ys,xe,ye,xs,ys); // Restore the background

if(pos>i) pos=0; txword(0xaa98); // Display text txxy(xs,ys); txword(0x2381); // The background color does not displayed with 32*32 Chinese //characters txbyte(0x03); txword(0xf800); // The color of typeface is red txword(0x0000); k=pos; for(j=0;j<8;j++) // Characters are displays at most 8 characters in each line



{ txbyte(str+k); k++; txbyte(str+k); k++; if(k>i) k=0;} pos=pos+2;} // Move the pointer’s position to achieve the rolling text. Only one //Chinese character

(2 bytes) is moved each time

2 CURVE

Command Description

0x40 Set palettes

0x56 Connection line in accordance with the specific points

0xC106 Zoom and display a two-way line chart of window limited with data in temporary buffer

2.1 Move Curve to Achieve Dynamic Curve Display Procedure: A. Use the 0x71 command to restore the background picture on (X, Ymin) (X+dX, Ymax) area in order to erase the previous curve; B. Use the 0x40 command to set a red foreground color. Use the 0x56 command to connect a red curve between (X, Y1now-1) and (X+dX, Y1now); C. Use the 0x40 command to set a green foreground color. Use the 0x56 command to connect a green curve between (X, Y2now-1) and (X+dX, ^2now); D. Use the 0xD0 command to compulsively refresh screen once to ensure a smoothly moving curve; E. X=x+dx. Repeat steps A-E. if(RTCOK) // It is time for A/D sampling {y1now=185-rdad(0x00)/2; // The first curve is the CHO 8bit A/D values, 185 is the zero point of Y

//axis. y2now=185-rdad(0x01)/2; piccut(0x71,3,x,ymin,x+dx,ymax,x,ymin); // Restore the current background to erase historical

curves setcolor(0xF800,0x0000); line(x,y1old,x+dx,y1now); setcolor(0x07e0,0x0000); line(x,y2old,x+dx,y2now); fdisp(); // Compulsively refresh once to display with AA D0 CC 33 C3 3C y1old=y1now; y2old=y2now; RTCOK=0; x=x+dx; if(x>Xmax) x=Xmin;}

Because of the limitation of serial communication speed and command executing time, the curve movement mode to achieve the dynamic curve display is only suitable for the low sampling rate (Usually lower than 10 times per second).



2.2 Dynamic Curve: Zoom and Playback History with the Movement of Windows

Users can temporarily store curves in temporary buffer. The current display window is just a “segment” of the entire curves. It is very convenient to move and playback curves by modifying the staring address in buffer. The result is shown as above. Automatically zoom the curve in temporary buffer and check the bounds of curves’ window with the 0xC106 command: if(RTCOK) // It is time for A/D sampling {WRbuffer(Buf_adr,rdad(0x00)); // Store A/D values to the temporary buffer Buf_adr++; WRbuffer(Buf_adr,rdad(0x01)); Buf_adr++; if(Buf_adr>40959) Buf_adr=0;} if(DSPOK) // It is time to display and refresh {piccut(0x71,3,xmin,ymin,xmax,ymax,xmin,ymin); //Restore the current window to erase the

//previous curves DisBufLine(Dis_adr,100,0xf800); // Display curve 1 DisBufLine(Dis_adr+1,100,0x07e0); // Display curve 2 Dis_adr=Dis_adr+200; //The width of window is 100 dots, two curves. Each time the length

//of entire window is moved if(Dis_adr>40959) Dis_adr=0; } void DisBufLine(uint adr,unit num,unit color) //Display curves in temporary buffer with the

//0xC106 {txbyte(0xaa); txword(0xc106); txword(adr); txword(xmin); txword(ymax); // The zero point position in Y axis. Set (ymin+ymax)/2, if the curve is negative txword(num); txword(0x0202) //Address intervals is 2 in temporary buffer. X coordinate intervals is 2 txword(0x0102) // Curve is enlarged by 0x01/0x02=0.5 times txword(color); txword(ymin); // Display the limitation of curves’ window txword(ymax); txeof();} The maximal length of DWIN UART LCM buffer is 40Kword and can store 40960/N sampling points at maximum (N is the curve number). The historical curves can be saved in a time of 204.8 seconds at a sampling rate of 200SPS (200 records per second) for one curve. Refer to Appendix 3 to see detailed applications of ASM51 code.



3 PICTURE, ICON AND ANIMATION

Command Description

0x70 Display a full screen picture saved in the terminal.

0x71 Cut an area from a picture which is stored in the terminal and then paste it on the current specific position

0x9C Cut an area from a picture which is stored in the terminal and then paste it on the current specific position after filtering the background color

0x9D

Cut an area from a picture which is stored in the terminal and then paste it on the current specific position after filtering the background color The 0x71 command is automatically executed once before pasting and restoring the background by the current page.

0x9E Cut an area from a picture which is stored in the terminal and then paste it on the current specific position after rotating specific angles. You can select to filter the background color when pasting. H600 and K600+ only

0x97 Displays an icon in ICON library. K600+ only

0xE2 Save current background picture to terminal.

0x59 Display rectangle with the foreground color.

0x69 Display rectangle with the background color.

0x5A Fill the rectangle area with the background color.

0x5B Fill the rectangle area with the foreground color.

0x5C Reverse the specific rectangular area (Restore the original display by reversing again).

0x64 Fill the specific enclosed area

0x9A Open/Close to be automatic commands cycle; the configure files of commands are saved in the 0x1C font.

Theoretically, any complexes GUI can be divided into icon to display because 24bit uncompressed pictures are supported by DWIN HIM.

3.1 Progress Bar Display

Take the progress bar above as an example. The procedure of achieving progress bar includes 5 steps (Cut pictures to achieve the crystal progress bar):

A. Use the 0x40 command to set the foreground color (Black frame) and background color (The white background);

B. Use the 0x59 command to draw a frame and use the 0x5A command to fill the background; C. Use the 0x40 command to set the foreground color (Black characters) and the background

color (The blue progress bar); D. Use the 0x5A command to fill according to the progress; E. Display the progress value using the text display does not have background (0x98,

C_Mode.6=0). stepdsp(100,100,0x0000,0xffff,0x0000,0x001f,100,75) // Display a progress bar. ( x,y) is the display position. w is the width of progress bar and height is //22. Font is 16 dots matrix and st is the progress.

void stepdsp(uint x,uint y,uint color1,uint color2,uint color3,uint color4,uchar w,uchar st) ｛setcolor(color1,color2); fillw(0x59,x,y,x+2+w, y+22); fillw(0x5a,x+1,y+1,x+3+w,y+21); // Display a solid rectangle



setcolor(color3,color4); fillw(0x5a,x+2,y+2,x+2+w*st/100,y+20); // Fill the progress bar hex2dsp(x+w/2,y+3,st); // Display the progress characters with 0x98 command, C_Mode.6=0 print98(0x21,0x81,0x01,color3,color4,x+24+w/2,y+3,"%");}

3.2 Analog Dial Display The analog dial is actually a “nonlinear” special progress bar. Directly use the 0x64 command to fill as shown in the picture below:

setcolor(0xf800,0x0000); // Set the connection lines to red line(30,55,40,56); // Line fillfree(48,100,0xf800); // Fill the semi-circle area with red // (x, y) is the seed point. Fill the arbitrary boundary around the area with “color” void fillfree(uint x,uint y,uint color); { txword(0xaa64);

txxy(x,y); txword(color); txeof();}

If the area boundary being filled does not connected by the convex polygon, the user program is needed to fill every area one by one.

3.3 Overlap Picture

Sometimes, pictures are overlap icons with the 0x9D command (Such as the battery icon in the

left-down picture above)： Firstly, design icons and save them in one picture. Note: The background color must be a solid

color (Such as the gray area in the picture). The result is shown as below：

Cut the corresponding area and paste it on the specific position with the 0x9D command based on the requirement, such as the above example:



logod9d(50,70,0,140,40,0,440); // Assume the battery icons are saved in the 50th picture Note: Automatically restore the background of current picture with the 0x9D command. So restore the background with the 0x71 command, if paste the icon which is cut from the other picture, and then display the icon with the 0x9C command. Recommend to use the 0x97 command in order to design and call icons easily for K600+ kernel DWIN screen.

3.4 Backup and Restore Current Screen

As shown in the picture above, users will often meet the occasion of “temporary interrupt” in current screen. The description is shown as followings: Users often need a dialog box (The keyboard in the picture above for instance) in current non-picture background (Text and curve). The previous background will be recovered after completing operation. It will be complex to record and refresh the parameters status. Users can use the 0xE2 and 0x70 commands to solve this problem. Use the 0xE2 command to backup and save current screen at a valid picture position (Such as

the fiftieth picture) before pop-up windows; Pop-up Windows; After finishing the operating windows, use the 0x70 command to restore the previous saved picture. The intrinsic picture memory of DWIN UART LCM uses NAND flash, which can save up to 100 thousand times in one picture location.



3.5 Pointer and Dashboard Display

Picture 0 picture 1 Overlap the picture 0 and picture 1 As in pictures above, the pointer has an intuitive, dynamic, strong sense of the characteristics. In many projects, the 0x9E command (H600 and K600+ only) could be used to achieve this effect easily. Separate the procedure of pointer design and dashboard as shown in picture 0 and picture 1, and put the pointer and 0’clock to make it easier to transfer by software. Save picture 0 and picture 1 to DWIN UART LCM terminal; In programs, calculate the rotation angle according the pointer’s position. Use 0x9E command to cut the pointer picture and paste it on the dashboard. Use the 0x71 command to restore the dashboard background in order to erase the last pointer position. posdsp(1.2); // Display the pointer position. The previous dashboard is in page 0 and pointer in //page 1

//value 0-1＝0-80°, 1-1.5＝80-135° 0－-1＝360-225° void posdsp(float value) {uint alpha; // The angle of rotating pointer if(value<0) alpha=360-value*135; // Calculate the rotating angles according to parameters else {if(value>1) alpha=80+(value-1)*110; else alpha=value*80;} alpha=alpha*2; // The Unit of rotating angle is 0.5° piccut(0x71,0,304,158,509,338,304,158) // Recover dial background to erase previous pointer display txword(0xaa9e); txbyte(0x00); // Filter out the background color txword(0x0001); // The pointer is in picture 1 txarea(761,483,790,586); //The area of pointer in picture 1 txxy(776,572); // The rotating center of pointer in picture 1 txword(alpha); // The rotating angle of pointer txxy(401,247); // The rotating center of pointer after being pasted on picture 0 txeof();}

Users can cut, rotate and paste any picture with the 0x9E command. So the 0x9E command can be used in many other applications:

The rotation of icons such as motors, gears and other circular motion; Design some cartoon icons. Modify the rotating angle and rotating center in order to achieve the rolling and bounce effect using 0x9E command to cut and paste icons. The “Compass display mode”: The display contents always points to operators, using the angle sensors to feedback, control and adjust (The gravity sensors or encoders).



3.6 Flowchart Animation (Auto executing at fixed time)

In the processing of display automated flowchart, we hope to show the dynamic process to users. So it involves a lot of small areas animation (Update contents at fixed time) in order to show the effect of the users’ movement, such as the operation of the conveyor, the flowing liquid in the pipeline and so on. If these animations rely on the user program to timing refresh, it will cause three problems: (1) Clients have to write a mass of codes. But these codes have to be modified in order to bring a lot of workload. (2) CPU resources will be occupied when data is sent frequently. (3) High-speed and large-scale animation effects cannot be easily achieved because of the limited speed of serial communication. It would be easy to handle these problems using 0x1C configuration files and 0x9A command. The specific procedure is shown as follows: A.

The design of human-computer interaction based on UART LCM is really closed to “zero code” by complete touching function and touch screen in both Chinese and English input function!

4.1 Touching Function Interface (User code without interference) Design

DWIN touching function interface software specifications



The steps of touching function interface development： Step 1: Design the user interface which is the same as the UART LCM physical resolution and it the UART LCM (Terminal).

Step 2：Use the "DWIN touching function interface configuration software" to generate a configuration file.

Step 3：The configuration file is downloaded to the UART LCM (terminal). Configure UART LCM to the touching function mode with the 0xE0 command.

Step 4：Match interface switching writing additional codes, such as the refresh of cures and parameters, input parameters and so on. Debugging and finalize the design. The user’s software structure is the parallel functional module of "Message trigger" using touching function mode for the purpose of debugging and easy maintenance.

4.2 Input Parameters on Touch Screen

Users want to pop-up the left-up dialog when clicking on the right-down “Clock” icon, and use this keyboard dialog to modify the time of clock. In this case, the 0x7C01 touch screen ASCII input command could be used to achieve this function easily. uchar CMD7C[]={0xaa,0x7C,0x01,0x00,0x01,0,1,0,34,0,40,12,3,0,0,0xcc,0x33,0xc3,0x3c}; if((Rxcmd==0x78)&&(Rxdat0==0x00)&&(Rxdat1==0x01)) // Receive touching function key codes { piccut(0x71,1,0,0,206,344,0,0); // Pop-up little keyboard by cutting icon mode

txstr(CMD7C); // Send the touch screen ASCII input command. Input is be completed by UART LCM } if((Rxcmd==0x7c)&&(Rxdat0==0x00)&&(Rxdat1==0x01)) //Finish touch screen input and check R_ID { piccut(0x71,0,0,0,206,344,0,0); // Close the little keyboard wrrtc(); //Input parameters are saved into serial port buffer } Users need to select an input return ID as “message” to trigger programs accessing to manage by the 0x7C command. In the processing of the 0x7C command, touch screen will be completely processed by UART LCM and data will not be sent to users. The other functions of UART LCM are normal. In other words, other programs are normally processed by users’ CPU when inputting parameters. It easily achieves multi-task management. As above example, clocks and hands will run normally while inputting the parameters to touch screen. 0x7C, H600 and K600+ only Refer to appendix 2: Clock to see the entire ASM51 code.



4.3 Input Chinese with Touch Screen (GBK font)

Users need to modify 24 different English/Chinese parameters with the touch screen using the 0x7C02 English/Chinese characters input command. Calling program of 0x7C02 command and 0x7C01 command are basically the same. This is ASM51 codes below:

MOV A,RXCMD ; Valid data frame is received with Serial port CJNE A,#78H,START2 ;Touching function key code MOV DPTR,#CMD7C1 ;Open English/Chinese input method LCALL TXROMS MOV R0,#RXDAT

MOV R7,#2 ;Use key code as the index of parameter return LCALL TXREG MOV DPTR,#CMD7C2 LCALL TXROMS LJMP STARTE

START2: CJNE A,#7CH,STARTE ;Finish and return the touch screen input MOV DPTR,#CMD70 LCALL

TXROMS ; Return screen 0 MOV A,RXDAT CJNE A,#02H,START20 MOV A,RXIDL ; Preinstalled R_ID to direct the parameter to be modified MOV B,#32 MUL AB MOV DPH,B MOV DPL,A MOV R0,#RXNUM MOV A,@R0 JZ STARTE ; Length of returned parameters data LCALL WRXRAM ; Save parameters

5.2 RTC Most of DWIN UART LCM has the intrinsic 2000-2099 RTC. RTC can be read and modified with commands. Or RTC is automatically overplayed on the specific background pictures according to the user’s need. UART LCM has intrinsic backup battery. RTC will run regularly when power is off.

void rtcon(unit x,unit y,unit color,uchar mode,uchar scale) //Activate RTC overlying display on (x,y) { txword(0xaa9b); txbyte(0xff); txbyte(mode); txbyte(scale); txword(color); txxy(x,y); txeof();} void rtcoff() //Turn off the RTC overlying display { txword(0xaa9b); txbyte(0x00); txeof();} void rtcset(uchar *s) //Set RTC, S=YYMMDDHHMMSS, BCD code, such as 0x11 0x07 0x25 0x12

//0x00 0x00 { txword(0xaae7); txword(0x55aa); txword(0x5aa5); txstr(s); txeof();} void rdrtc_en() //Read the Gregorian calendar and return BCD code. The format is YY MM DD

//WW HH MM SS. WW is represented week. { txword(0xaa9b); txbyte(0x5a); txeof();} void rdrtc_cn() //Read the traditional Chinese calendar. The format is YY MM DD { txword(0xaa9b); txbyte(0x5b); txeof();}



5.3 Backlight Brightness Adjustment and Screensaver Brightness Setting The 64-step backlight brightness adjustment is valid for all of LED-backlighting DWIN UART LCM. Backlight switching on/off is supported by the minority of CCFL backlight UART LCM in order to avoid reducing the lifetime and effect of light when adjusting the brightness.

light(50); //Adjust backlight brightness to 50% void light(uchar i) //Correspond to 0-64 steps of brightness adjustment, when i=0-100% {txword(0xaa5f); txbyte(uchar((i*64)/100));}

In some applications, the user needs to control the brightness of screensaver： Set brightness at L1 when operating regularly. Set brightness at L2 when operating infrequently. The user does not click on the touch screen or

keyboard for a long time. When screensaver brightness is L2, if clicking on the touch screen or keyboard, the first

operation is ignored but the backlight brightness will be adjusted to L1. It only needs modulation once for touch screen UART LCM using 0x5E and 0xE0 commands. lightset(100,20,10); //Set the normal brightness at the maximal brightness, screensaver

//brightness at 20% and touch screen trigger time at 10 seconds; //Set the touch screen backlight control: brightness is L1, screensaver

//brightness is L2 and touch screen trigger time is t (0-127) second; void lightset(uchar l1,uchar l2,uchar t) {rdconfig(); //Read configuration parameter back; PARA1=PARA1|0x10; //Set the backlight brightness can be controlled by touch screen; wrconfig(); //Configuration parameters is modified with the 0xe0 command; txword(0xaa5e); txxy(0xaa55,0x5aa5); txbyte(uchar((l1*64)/100)); txbyte(uchar((l2*64)/100)); if(t>127) t=127; txbyte(t*2); txeof();}

5.4 Visual Angle Adjustment Any visual angle is adjusted with 0xE0 (Or 0xE3) command in DWIN UART LCM. The result is shown as follows:

”DWIN Technology” in the pictures above are written on (0,0) with the text display command. Users must implement particular settings when downloading pictures. The picture is shown as follows:



Select Toolbar 0° =0°and 180°； 90° =90°and 270°.

5.5 Read/Write Intrinsic Database

DWIN UART LCM has an NAND Flash database which is at most 30.063MB (30MB ranked storage and 64KB random storage). The user can read and write data using 0x90 and 0x91 commands in order to record and storage data on second development time. void wrdbaser(uint adr,uchar *s) //Write the random data memory { txword(0xaa90); txword(0x55aa); txword(0x5aa5); txword(0x01de); txword(adr); txstr(s); txeof();} void wrdbases(long adr,uchar *s) //Write the random data memory { txword(0xaa90); txword(0x55aa); txword(0x5aa5); if(adr>0x01ddfffff) adr=0; //Check it whether the address is overflowed txlong(adr); txstr(s); txeof();} void rddbaser(uint adr,uint len,uchar *s) //Read the random data memory {uint i; txword(0xaa91); txword(0x01de); txword(adr); txword(len); txeof(); //Receive data. Serial port must be big enough if read-back data is excessive. Otherwise take the inquiry

//receiving mode as follows EA=0; //Close interrupt while(!(RXDATA==0xaa)) rxbyte(200); //Receive a byte in serial port. Exit if serial port does not received or

//exceed time in 200ms for(i=0;i<6;i++) {rxbyte(200);} for(i=0;i<len;i++) {rxbyte(); *s=RXDATA; s++;} EA=1;}



void rddbases(long adr,uint len,uchar *s) //Read sequential data memory {uint i; txword(0xaa91); txlong(adr); txword(len); txeof(); // Receive data. Serial port must be big enough if read-back data is excessive. Otherwise take the query

//receiving mode as follows EA=0; //Close interrupt while(!(RXDATA==0xaa)) rxbyte(200); //Exit if the serial port does not received or exceed time in 200ms for(i=0;i<6;i++) {rxbyte(200);} for(i=0;i<len;i++) {rxbyte(); *s=RXDATA; s++;} EA=1;}



5.6 Video play Analog video (CVBS signal such DVD video output and camera video output) or digital multimedia video in SD card (DVD, MP3 or MP4) is supported by certain DWIN UART LCM products. All of these videos will be played in full screen mode. So the user needs to switch between UART LCM mode and video mode. videoplay(PAL,0x00) //Play video in CHO channel and PAL format sdplay(PLAY); //Play video and music in current folder sdplay(NULL); //Play analog video #define PAL 0x00 //PAL video #define NTSC 0x01 //NTSC video //Play digital video #define NULL 0x00 //Null operation. Send this program once when leaving buttons #define PLAY 0x01 //Play and stop #define SPKON 0x02 //Turn on loudspeaker #define SPKOFF 0x03 //Turn off loudspeaker #define ENTER 0x04 //Confirm #define DOWN 0x05 //The next one or fast forward #define UP 0x06 //The previous one or fast back #define CANCEL 0x07 //Cancel #define SPKADD 0x08 //Turn up volume #define SPKSUB 0x09 //Turn down volume #define LANG 0x0a //Switch between Chinese and English menu void UART LCMmode() //Back to UART LCM mode { txword(0xaa7a); txbyte(0x00); txword(0x0000); txeof();} void videoplay(uchar mode,uchar ch) //Switch to analog video mode { txword(0xaa7a); txbyte(0x01); txbyte(mode); txbyte(ch); txeof();} void sdplay(uchar sdkey) //SD digital video playing management { txword(0xaa7a); txbyte(0x01); txbyte(sdkey); txeof();}

The functions of UART LCM are run normally in video mode without displayed in the touch screen.

5.7 Buzzer Most of DWIN UART LCM has a buzzer for the touch screen. The user can also send commands to control a buzzer: buzzon(100); //Buzzer beeps 1 second void buzzon(uchar ontime) //Set buzzer time. The unit is 10ms { txword(0xaa79); txbyte(ontime); txeof();



6 RECOMMENDATION OF USER’S PROGRAM DESIGN

The user’s program is basically simplified into two functions for the users who use DWIN UART LCM as human-machine interface, especially DWIN UART LCM touch screen users:

The user is very familiar with the realization of products algorithm function, such as data collection, peripheral control and so on.

Normally the user is not very familiar with the realization of human-machine interface function with DWIN UART LCM.

DWIN UART LCM is communicated through the serial port with user programs which are the relatively independent system and manage the “random” cases (communicate with the user). But the algorithm function deals with “fixed” cases. So programs should be structured in the method as following in order to improve the efficiency of the R&D and program stability:

Adopt the program structures of the foreground/background. The applications programs are put in the foreground to be managed with the query and scan mode. The programs which directly communicate with hardware are put in the background and managed by interrupt mode, such as serial port, A/D conversion The foreground and background programs are exchanged data by memory (The global variable). The foreground programs are triggered by background message. Use a timer to generate intrinsic order to coordinate the different application programs. All of the programs are designed into the independent parallel subroutines in the foreground according to functions in order to be tested and transmitted (Several engineers can work independently at the same time and integrate after testing).

The procedure of development with DWIN UART LCM touch screen:

The hardware designer designs hardware; The professional designer conducts the interface design (It is extremely important to design the interface in all procedures. The professional GUI designer only need to be paid at 50-200 RMB per page ) The touch screen configuration interface is designed by DWIN touch screen configuration software. Test and revise for customers. The procedure can be divided into some independent procedures to develop if software designs a lot of functions. Integration, debugging, test, check and finalize the design.

Please refer to codes in the case of appendix to see the detail software structures.

Software Upgrade

DWIN_M600_BOOT! Kernels software are upgraded online by serial port

The sequence of kernel development keeps downward compatible with command set. The

development order is : M100、M600、K600、H600、K600+ kernel. M100 kernel and M600 kernel command set are completely same; Kernels above K600 have different drivers. So we increase the 0xD0 command on the basis of

M100、M600；K600, M100 and M600 kernels command set are completely same;

Under the premise of H600 compatible with K600, we add the 0x7C、0x9E and 0xE3 commands. The part of serial port screens support SD card to download;

Under the premise of K600+ compatible with H600, we add the 0x97 command. Download is completely supported with SD card in corresponding serial port screens;
