( Sorry about my absence from the list, lost my desktop computer and email, working from the archive and web based mail ) =======Begin Prior Post: ======= 2007\01\25@001004 by John Chung Russ, Can you pls trim down your code again and just leave the PWM part only. Pls post it again. Once again, the problem MUST exist after the trimming. Do also provide the schematics for the new code. Leave out the loads and replace it with LEDs. It should help us narrow it down plenty. John PS: If you would like a fresh idea to the problem. Start a fresh with the code first. Start with blinky leds first and put in the original code one at a time. Subroutine the code properly so that you can know where it is failing at. ====== End Prior Post: Russ Says ===== Trimmed down and posted see this link. No stepper loads, still erratic. Am working on yet more versions of the code. Current stripped down version of code and circuit linked to thru: http://home.comcast.net/~russ_hensel/Erratic/index.html Thanks Russ -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
