I have a problem with my new PIC circuit. 18F2221. I try to program with my USBProg. I get the following error: Verification error at program memory address 300005h. Expected 17h, found 7h. 300005h is a config register: 7 MCLRE 6 - 5 - 4 - 3 - 2 LPT1OSC 1 PBADEN 0 CCP2MX 7h should be valid. 17h should be impossible, right? .. So I added the config directive: CONFIG LPT1OSC = OFF Rebuilt, programmed, verified, and it worked. Changed back to: CONFIG LPT1OSC = ON And it worked still. I'm not complaining, but does anyone know why that would happen? It makes me wonder what else is going on. - Martin -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
