Hello,

    A friend and I are currently trying to connect two PIC 18F452 chips together (each hooked up to an LCD screen) with a serial cable so that we can send/recieve messages to/from each other using a keypad we have hooked up as well. We're running into a whole slew of problems trying to get the PICs to communicate with each other.
    We've been coding in assembly and have tried to utilize the USART feature in order to press a button on one PIC to blink an LED on the other, just to get some basic communication going on and work our way up from there, but whether or not we try it in asynchronous or synchronous mode we can't see anything happening.
    Here is one way we tried to accomplish this http://my.fit.edu/~cbecker/final/final.asm , if you could help us out in any way it would be greatly appreciated, I have a feeling it's some simple error in the way we're trying to establish communication that's holding us up.

Thanks,

Cory
