I have a project that pic16f84a interface with LCD HD44780.... the LCD display word but it like "on and off" which mean the "hello world" word is there for a second and disappear and there again.......
I don't program the PIC in C language, so i can't say if the code is right or not. But, if i understand you well, i think the problem is that you turn on the watchdog timer.
Turn off the watchdog timer and try again.
mainly two reasons
1. you have sent the command to clear the LCD display
2. watchdog timer may be on
try to clear that command which will clear lcd and turn off the watchdog timer.
Because watchdog timer resets the controller whenever it gets overflow.
Before the overflow it should be cleared by the software.
so dont use watchdog timer in your code
