Hello all, Despite all the things I have tried in the last few months, I STILL have not got a successful program loaded into my 16f628. I am using TLVP with David Tait's FPP. I HAVE verified that the parport works by using FPP's debug function, and every pin works out as it should. I have rewired numerous times from scratch to ensure no errors. Initially, I had a longer parport cord (6'), but I made my own that was much shorter. I thought maybe this was the problem, but it works with the debug feature.. I verified each pin's voltage high and low with a DMM while switching them with FPP's debug feature. Even the read pin works fine, as it shows in the debug section. I have increased the cycle delays to mad numbers that are extremely high, and still nothing works. It just sais Read: 3FFF expected: 2828 (as 2828 was the first code to program). What is going on? I am getting desparate here for nothing has worked. I have even switched PIC's. Jai -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
