Hi, I have a PIC16c57. An elementary program I wrote runs fine on it. A secondary piece of code runs fine in the simulator, but nevers runs on the hardware (same hardware that runs a simplier but similar program). Is there any known traps that I particularly should watch when I goto the hardware? I have spent the last two weekends on this problem, so any advice would be appreciate. I am happy to send my code to anyone that may help solve the problem. regards Gary Gaskell DSTC Cooperative Research Centre for Distributed Systems Technology Queensland University of Technology Ph +61-7-864 1051 FAX +61-7-864 1282 Email gaskell@dstc.qut.edu.au
