Are you sure that your __delay_ms() function accepts non-integer values? I'm almost certain that it doesn't, and as a result all your delays are zero-length.

If it works with Proteus simulated LCD, it also means the simulated LCD does not work like a real word LCD. Which document you used to write the code? Have you read any LCD data sheets how to make it work? | |
