Has anybody interfaced an LCD module(having driver on board) with ST7 ? If yes..Can i have the software code for that?

Attached code will work with any HD44780 based lcd.

Adjust port setup in lcd.c to suit your application.

Use as:

LCDSetup( FOURBIT );

PrintData(ROW1,0,''hello'');

Hope this helps.

Yes,but it is for the LCD glass in which we are emulating the hardware driver with the software driver. I required for LCD Module.

There is one function //// data= GetLCDLineIndex( line, position );/// which is not given in the file. Can you tell whats the output of this fuction?

All this function does is return the ddram address for the particular line/offset, The code I sent is taken from an lcd tester unit.

eg. for a 16x4 lcd

GetLCDLineIndex( LINE2, 0 ) would return 0x40.
