Hello!
Why this code is not displaying "Cytron Tech" on LCD. The same code if compiled on another system is displaying on LCD, but if compiled on my system the LCD is blank.
It is a Hi Tech C Code. The kabian4.hex displays data on LCD but uart1.hex doesn't display anything on LCD. Kabian4.hex uses the same code but compiled on a different machine. can somebody compile the code for 20 MHz and post the hex file?
