Dear majerv, Add these functions to your program. You can display the time value on your screen. But this display function is for T6963C drived screen.If you use KS108 or LM series LCD's (40x2 , 20x2 alphanumeric LCD) or anything else, you need yo modify this code.

Code: Select all

void Display_Time(char sec, char min, char hr, char day, char mn, char year);void Zero_Fill(char *value);

//‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Output values to LCDvoid Display_Time(char sec, char min, char hr, char day, char mn, char year) { T6963C_waitReady(); ByteToStr(day,tnum); txt0 = rtrim(tnum); Zero_Fill(txt0);

T6963C_waitReady(); ByteToStr(day,tnum); txt1 = rtrim(tnum); Zero_Fill(txt1); T6963C_write_text(txt1 , 9, 5, 1) ; //LCD_Out(1,6,txt); T6963C_waitReady();

ByteToStr(mn,tnum); txt2 = rtrim(tnum); Zero_Fill(txt2); T6963C_write_text(txt2 , 12, 5, 1) ; //LCD_Out(1,9,txt); T6963C_waitReady();

ByteToStr(year,tnum); txt3 = rtrim(tnum); Zero_Fill(txt3); T6963C_write_text(txt3 , 15, 5, 1) ; //LCD_Out(1,9,txt); T6963C_waitReady();

ByteToStr(hr,tnum); txt4 = rtrim(tnum); Zero_Fill(txt4); T6963C_write_text(txt4 , 9, 6, 1) ; //LCD_Out(1,9,txt); T6963C_waitReady();

ByteToStr(min,tnum); txt5 = rtrim(tnum); Zero_Fill(txt5); T6963C_write_text(txt5 , 12, 6, 1) ; //LCD_Out(1,9,txt); T6963C_waitReady();

Hi! This may be in case if you use MikroC without activation key and you program use more then 2K program memory (demo limit from mE). Regards!

} while( 1);}

hey dude ,is this code works without any error.... but in my system its showing the error as demo limit help me yar..... thank u.....

Hello,

your code is ok, i compilated it with PIC16F877A and results:

Used ROM: 4734 octets Used RAM: 148 octets

So you are beyond 2Ko... (2734 octets in overflow)

In the main program you have to declare PORTB as output.That means you have to write TRISB =0,and it will work.

Hello! dronology

A part of my code is like this





Post subject: Re: DS1307 MikroC Library Posted: 08 Aug 2013 05:52

Code: Select all

void Write_Time() { I2C2_Start(); // issue start signal I2C2_Wr(DS1307); // address DS1307 I2C2_Wr(0); // start from word at address (REG0) I2C2_Wr(0x80); // write $80 to REG0. (pause counter + 0 sec) I2C2_Wr(0); // write 0 to minutes word to (REG1) I2C2_Wr(0x17); // write 17 to hours word (24‐hours mode)(REG2) I2C2_Wr(0x02); // write 2 ‐ Monday (REG3) I2C2_Wr(0x04); // write 4 to date word (REG4) I2C2_Wr(0x05); // write 5 (May) to month word (REG5) I2C2_Wr(0x01); // write 01 to year word (REG6) I2C2_Stop(); // issue stop signal

I2C2_Start(); // issue start signal I2C2_Wr(0xD0); // address DS1307 I2C2_Wr(0); // start from word at address 0 I2C2_Wr(0); // write 0 to REG0 (enable counting + 0 sec) I2C2_Stop(); // issue stop signal}

In that I want to know what value I have to write in this code

Code: Select all

I2C2_Wr(0x17); // write 17 to hours word (24‐hours mode)(REG2)

to make the clock work in 12 hr mode? I also want to display AM and PM.

ThanksJayanth D

Hi from totally newbee

I use MikroC 6.0.0 and tried to run this code but i only got a lot of ERRORS.

What is the problem, have they changed so the old I2C_Start must be changed to I2C1????

And the same with the Lcd Config?

If the problem is MikroC 6.0.0 i must downgrade to version 4 to get it to work??

Thanks in advance

Hi,

Our RTC2 click features the DS1307 serial real‐time clock (RTC),so please, take a look at RTC2 click examples:http://www.libstock.com/projects/view/2 ... ck‐example

The example is written for EasyPIC v7 ‐ PIC18F45K22, but with the help of PIC16F887 datasheetyou can try to adjust the example to work with your microcontroller/hardware.

Best regards,Marina

Hi am using mikroC compiler for 8051.In this compiler rtc interfacing with 8051 library is given.it works but it do not displays todaysdate & time value plz help me

this is the code
