If I put my chip in the picstart programmer backwards will it destroy the chip. I think so because everytime I'm in MPSIM and go to PicStart Plus to Enable Programmer. instead of recognizing that the chip is a 16c84...it think's it's a 16c54. I'm really a newbie.....I was wondering, on the Enable programmer window, is there suppose to be a OK button? I really would like to download some code to the chip it self, but I'm having a hell of a time trying to do this. All and any help from the list will be GREATLY appreciated. :) Thank You in Advance.
