lcd.c ccs

printf(LCD_PUTC, "hello world");
thats it.
also please check c:\program files\picc\examples directory
(ex_admm.c , ex_lcdkb.c)
there are lcd applications. in these files.

according to lcd.c(this file is driver for lcd) c:\program files\picc\drivers

// As defined in the following structure the pin connection is as follows:
// D0 enable
// D1 rs
// D2 rw
// D4 D4
// D5 D5
// D6 D6
// D7 D7
//
// LCD pins D0-D3 are not used and PIC D3 is not used.

U can use PortB or PortD as lcd port by define in lcd.c file
Regards.

ccs lcd.h

Hi,

You should include necessary header files to code.For example is you use lcd, you should include instant lcd header like #include <lcd.h> If you bother optimized code, i heard hi-tech produces more optimized and short code vs ccs.I didn't try it but heard. Good luck ;)
