GENERAL INFORMATION

The KDX xxx family card is composed by interesting boards that solve the operator interfaceproblems inside the automation field, in a low cost and efficient way. All the cards are composed bytwo indipendent sections: one for an external matrix keyboard acquisition and the other for LCDor Fluorescent (VFD) display management. Both the sections are driven by only two 8 bit parallelports, at TTL level. In this manner all the cards provided of at least 16 TTL lines on a standard 20pins I/O ABACO® connector, can be connected to KDX xxx modules and they can easily exchangedata and informations with the user.The greater part of grifo® control cards can be connected to these cards with the possibility to usemany different microprocessors (Z80, 8086, 8051, 68HC11, etc.) and proper software packages(BASIC, C, PASCAL, etc.). For some coupling of control cards and software tools, together withKDX xxx is provided a proper management firmware that drives the keyboard and the display at highlevel, with considerable facility and time saving. In fact this firmware let the user manage displayand keyboard directly with the high level console instructions as PRINT, PRINTK, KBHIT, INPUT,SCANF, KEYHIT, etc.The wide range of different displays models let the user select the best configuration according withthe application requirements, in terms of: price, visibility, dimension, graphic, alphanumeric,consumption, etc. Also the keyboard can be choosen by the user starting from some simple keys (i.e.push buttons, joystick swithes,...) up to complete 6x4 matrix keyboard (i.e. phone keypads, vandalresistance keys,...).The KDX xxx hardware structure is designed to simplify the software management of the card andto minimize the necessary lines for its management; moreover the connectors position and themounting holes ensure a fast installation of the card inside the electric panel.

KEYBOARD

KDX-xxx has an interface for a matrix keyboard with 6 columns by 4 rows that can manage up to24 keys. Some of the 10 lines necessary for kyboard acquisition are used also by display interface,but a specific interface solves this situation and avoids software complications. There are manydifferent commercial or not commercial products that can be directly connected to KDX-xxx as forexample:- keyswitches (rocker, sealed, miniature, low profile, pcb, etc.)- push buttons (stop, start, up down, mushroom, rotary selector, etc.)- joystick- keypads (numeric, hexadecimal, function, miniature, sub miniature, self adhesive, membrane, etc.)- keyboards (ascii, sealed, silicon rubber, vandalic resistant, etc.)Thanks to this simple keyboard KDX-xxx solves in an inexpensive way the problem of data input,even in case of several data. Connection to industrial keybards and/or anti vandalic keypads allowsto use it also in dangerous environments and to warrant a long operative life in any condition.For detailed information about connection and management please read proper following chapters.

DISPLAY

KDX-xxx is available with Fluorescent VFD or backlit LCD displays provided of differentfeatures. In detaily, following alphanumeric displays can be connected:

LCD 20x2 characters -> KDX-C2LCD 20x4 characters -> KDX-C4LCD 20x4 big characters -> KDX-C4BLCD 40x2 characters -> KDX-C24VFD 20x2 characters -> KDX-F2VFD 20x4 characters -> KDX-F4VFD 40x2 characters -> KDX-F24

and the following graphic displays:VFD 140x16 pixels -> KDX-GF2VFD 140x32 pixels -> KDX-GF4

LEDs backlighting of LCD models ensures a good visibility even when the environmental lightingchanges and if it necessary the user can modify the contrast regulation by acting on a specific trimmer.Another important features of KDX-xxx displays is their wide viewing angle that allows a goodvisibility from each frontal position.The user must choose the right display (so the right KDX-xxx model) that is sufficient for theinformation to visualize and for his visibility requirements.For specific requirements on current consumption, visibility and price the card can be provided withLCD display not backlit: for detailed information about these options and their availability, pleasecontact directly grifo® offices.On the board there are three specific connectors that has been deisgned to simplify the connectionof each displays, which is made through a direct soldering on the printed circuit (default configuration)or trough a simple flat cable. Either for this different mounting or a different display model, thecustomer can order the KDX-000 that is provided without display.Further information on each display are reported in DISPLAYS MANAGED chapter.

CONTRAST REGULATION TRIMMER

On KDX-xxx board there is a trimmer that defines the contrast on LCD displays. This trimmer,named RV1, is set by grifo® to obtain the best display visibility in each working conditions andnormally the user must not change its position. In case of specific requirements, as external light verylow or very high, it can be changed by little rotation in both directions until the visibility is improved.For recognizing the location of contrast regulation trimmer, please refer to figure 6.

I/O CONNECTION

To prevent possible connecting problems between KDX-xxx and the external systems, the user hasto read carefully the previous paragraph information and he must follow these instrunctions:

- For all TTL signals the user must follow the rules of this electric standard. The connecteddigital signal must be always referred to card digital ground. For TTL signals, the 0V levelcorresponds to logic state 0, while 5V level corrisponds to logic state 1.

- Location of signals on all display connectors (CN4, CN5, CN6) is the same as the one on thedisplays, provided with the same connector type. When display is directly mounted onKDX-xxx printed circuit it is sufficient a male strip soldered on both sides: this is the standardconnection performed by grifo®. Viceversa when KDX-000 is ordered and the display ismounted far from the card, two male low profile connectors must be soldered: one on the backside of display (those without glass) and the other on component side of KDX-000. Afterthese two male connector can be linked through a common and cheap flat cable 1-by-1. Thislatter can be ordered from grifo® with codes: FLT 16+16 40 cm or FLT 20+20 40 cm.

- For all the displays featuring a connector mechanically incompatible with the correspondingon KDX-xxx, just connect the signals with the same name or the same function. To make this,it is possible to use a flat cable with standard female connector by card side and the sameconnector with proper connections by display side.

- To avoid driving problems and minimize the effects of eventual noises from the field,connectors CN2, CN4, CN5, CN6 can be connected with cables of maximum length 40 cm.

DISPLAYS MANAGED

Hardware structure of KDX-xxx can use most alphanumeric and graphic intelligent displayscurrently in commerce, both LCD and VFD fluorescent.As an example below is reported a list of displays tested, complete with type, part number,manufacturer and connector to use on KDX-xxx.

To recognize these valid connections, please refer to the board printed diagram (serigraph) or tofigures 11 and 12 of this manual, where the pins numeration is listed; for recognizing jumper location,please refer to figure 6.The "*" denotes the default connection, or on the other hand the connection set up at the end of testingphase, that is the configuration the user receives.Further information about purpose of jumpers are reported in the following paragraphs POWERSUPPLY.

POWER SUPPLY

KDX-xxx interface is provided of two different connectors that solves in a efficent and comfortableway the problem to supply the boards in any situation. On the boards there are some different sections(keyboard interface, display, LCD backlight, LCD contrast, etc) featured by different consumptionsbut with the same power supply voltage: +5 Vdc ±5%.As described in the previous paragraphs there are two different connectors that supply power to thecard; each one of these normally is connected to a group of section as below described:

CN1 -> connected to high consumption sections = FUTABA VFD display on CN5 = LCD LED backlight on CN4 or CN6

CN3 -> connected to low consumtion sections = Keyboard interface = LCD or VFD display on CN4 or CN6 = Contrast voltage generation

The GND signals of both connectors are always connected together and with the other GND signalsof the card while +5 Vdc signals are separate. The jumper J1 can be used to connect together the two+5 Vdc signals, allowing the use of a single power supply signal for all the card sections.So the typical uses of jumper J1 are the following ones:

- When the control system connected to CN3 has enough current for all KDX-xxx sections, J1must be connected and the single power supply of the control system will completely powerall the interface.

- When the control system connected to CN3 has not enough current for all KDX-xxx sections,J1 must be not connected and a second power supply must be connected to CN1.

- The configuration J1 connected can be used also to carry in or out the single power supply (i.e.connect an external load to +5 Vdc of the control system, through CN1 connector; connect a+5 Vdc to CN1 and supply power to the control system through CN3, etc.)

The card is also provided with a distribuited filtering circuitery that saves the terminal from disturbsor noise from the field, improving the overall system performances.For further information please refer to paragraph ELECTRIC FEATURES and to APPENDIX Awhere is reported the electric diagram of the card.

SOFTWARE DESCRIPTION

In the previous paragraphs all the hardware lines have been described and here follows a detaileddescription of function and meaning of digital I/Os (please always refer to the connectors figures tounderstand completely the following informations or to electric diagram in APPENDIX A).In the following paragraphs the indications D0÷D7 or .0÷.7 are used to refer the bits of thebyteinvolved in the I/O operations. Obviously this manual doesn't report information about themanagement of the 16 digital I/O lines in fact these depend on the used control system and the usermust search them in the proper technical manual.The software management of KDX-xxx can be performed in two different manners: high level andlow level mode as described in the following paragraphs.

HIGH LEVEL MANAGEMENT

This modality coincide with a firmware already developed and supplied by grifo® under the formof drivers or libraries. By adding this firmware to the used high level programming language (C,BASIC, PASCAL, etc.) the user can manage the keyboard as a console input device and the displayas a console output device. So all the high level instructions dedicated to console management areavailable for KDX-xxx management too, and the typical problems of data insertion, functionsexecution, formatted information visualization, and so on, are easily solved. In detail, according withprogramming languages, the following instructions directly act on KDX-xxx resources:

BASIC -> Print ; Input ; InkeyC -> Printf ; Puts ; Putch ; Getch ; Getche ; Scanf ; KbhitPASCAL -> Write ; Writeln ; Read ; Readln ; Keypressed

Thanks to the high level management the part of application software dedicated to operator interface,that often is one of the most important and difficult problems, is easily solved by any user with a greatreduction of development time.Actually grifo® has several ready to use high level management firmware for many microprocessorsand some different software tools, as:

Z80 based cards through GDOS or FGDOS romate operating system,I51 based cards through BASIC 52, BASCOM 8051 and µC/51,I86 based cards through GCTR,AVR based cards through BASCOM AVR and ICC AVR.

and detailed information about firmware integration, initialization procedures, console redirection,etc. are reported in the user manual of the same software tools.

LOW LEVEL MANAGEMENT

In this modality all the KDX-xxx resources are managed directly by user application program thatmust use the 16 digital I/O lines to drive display and acquire keyboard. Thus the applicationdevelopment will require more time and more knowledge, because everything (timing, lines,interrupts, formatting, ....) must be realized by the user.

FIGURE 25: KDX-F24 AND .KEY4X4 PHOTO

grifo® ITALIAN TECHNOLOGY

Page 26 KDX-xxx Rel. 5.00

KEYBOARD

The keyboard management coincide with a periodic operation that checks if there is a pressed keyin that specific sample time or, in other words, if there is a cross row - column of the matrix connectedby a closed contact of the relative key. Each sampling time the scan procedure composed by thefollowing steps, must be performed:a) Disable the connected display by setting properly its control signals.b) Set the first column (Col 0) to low level by resetting the relative output lines to 0 logic state,

and mantain all the other columns to high level (logic state 1).c) Acquire the four rows status (Row 3 ÷ Row 0) by reading the status of the relative input lines.d) Check if some of the four acquired Rows are at low level (logic state 0): in this condition the

key connected on the cross Col 0 - Row n is pressed and viceversa.e) Save an index, counter, number, code according with software requirements, of the found

pressed keys.f) Repeat the steps b, c, d, e for the remaining columns (Col 1 ÷ Col 5).To ensure that no key pressed are lost it is suggested to perform the described scan at regular timeinterval, for example each 5 msec, by using a periodic interrupt responce routine associated to a pre-setted hardware Timer. To avoid wrong identifications of not stable pressed keys (recoils are typicalin these condtions) it must be used a debouncing tecnique that defines the key really pressed whenit has been found closed for at least 20 msec, equals to 4 sucessive scannings.The correspondences betwwen the matrix keyboard lines and the digital I/O lines on CN3 are belowreported:

PA.0 -> Col 0PA.1 -> Col 1 PC.7 -> Row 0PA.2 -> Col 2 PC.6 -> Row 1PA.3 -> Col 3 PC.5 -> Row 2PA.4 -> Col 4 PC.4 -> Row 3PA.5 -> Col 5

DISPLAY

The intelligent display management is based on a parallel communication performed through an 8bit data BUS and 3 control signals. The software must drive all these lines according with displayspecifications, in order to send commands and/or data to be displayed.The correspondences betwwen the display lines and the digital I/O lines on CN3 are below reported,both for standard display , FUTABA display:

PA.n -> DBn , DBn PC.0 -> RS , ----PC.1 -> R/W , ----- PC.2 -> E , /SELPC.3 -> ----- , /WR

When the software busy status of the display must be acquired, PA.n lines must be bidirectional,viceversa if proper delays are inserted in the software the 11 signals can be simple output lines.In normal applications the following operations must be executed to correctly use any type of display:a) Defines the digital I/O lines functiobnality according with signals direction.b) Initialize the display by sending proper commands.c) Send characters to display or command to be executed (i.e. clear, cursor shift, set addresses)

according to application requirements.A complete description of control signals waveforms, display commands,initialization sequence,characters locations and characters fonts are available in APPENDIX B and C of this manual.
