Hello,
Please could you help see if this C code has got any faults in it? It builds OK, but I wonder if it will work?
It uses the PIC16F18856. It just puts it through its paces. We have a new board arriving on Friday, and we must get it working by Friday to go to a show and be programmed by the software engineer.
The software engineer will kill us if the board isnt good....so we want to get the micro to do some basic stuff like taking pins high and low.....to see if the board's ok
//TEST CODE FOR "590P" Board
//This just exercises the basic features of the board
//so that we can see that the board is good.
