Hi all, I've been using PICkit3 and IPE to program a PIC18F chip via ICSP for a project. All seemed to work fine. I noticed a problem in my code whereby the wrong character was being received from the serial port to the PC. I could not find out why this occurred so I used IPE to verify the chip and was reported as ok. After much head scratching and still no joy, I reprogrammed the chip with the same HEX code and now the problem is fixed and IPE still verifies ok. Also unless I am missing something, it won't let you read a chip unless a HEX file has been loaded. Anyone else had problems. cheers Tony --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
