Rob, We've just been discussing a very similar problem in the thread "[PIC]: Unexplained Programming Error PIC16F84". Check that out. Dave -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU] On Behalf Of Robbie Werner Sent: 14 March 2002 04:27 To: PICLIST@MITVMA.MIT.EDU Subject: [PIC]: Programming error in 'PIC All' Hi all, I've been trying to get 'PIC All' to work with a P16Pro PIC programmer but I am getting an error whenever I try to program the PIC. I can read data off the PIC ok, but when I try to write I get an error. The error message is in a dialogue box called 'Verify' and says: | Program error: | | Program: address=0000 buffer=2810 device=3FFF Any thoughts as to what might be causing this? Also, what values should I set Start Prog, End Prog, SN/ID, and Fuse/Prot to? Any help greatly appreciated, -Rob -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
