Hi Harlequin2,
It looks like DJ’s link is still active back on post 386. Don’t think the C conversion was ever finished.
Looking at what would be applicable within my code, I’d say driving the LCD, UART and reading/writing to EEPROM. I wonder if it would be easier to use available CCS C libraries for the PIC?
Example HD44780 16x2 LCD code (4-bit mode with R/W tied low) was found here-
