Well thanks for the replies, but still no luck. This should be the easiest bit of the project. Isnt it always the way.
I have included the code. Display is the transmitter, and fback3 is the receiver. The programs control a welder, display is supposed to tell the feedback chip the desired welding current. I can see the serial input to the pic on the scope but still no output mirrored on the test pin. I have also tested the pins as digital in and out, so i know there is no damage to the chips. I have also written code just to test the comms part with but no difference
By the way in the display file is a routine to drive a 4 digit 7 seg led display, with blanking of leading zeros. Quite proud of that little routine.
Thanks again for the help. Hope we can sort it out soon, the boss is back on tuesday :-( lol...
Regards
Bob
