Hi all, Noticed this a while ago, whilst working on my timer things. It has now become a serious problem (well, very annoying at least). Every time I run my program on my chip, I find I need to remove power from it for a second, or the MPLAB ICD2 refuses to program, in either programmer or debugger mode - it either says the device ID is 0, or it failed to verify. After unplugging the power supply for a second, it programs fine then. I have checked the PIC isn't damaged - it does exactly the same on 2 different 16F87s. It only apears to happen with one particular project - all other projects work absolutly fine. Also, when using the ICD2 in debug mode, after pausing the program once, if I try to restart the program, it keeps saying the target isn't in debug mode until I pull the plug for a second. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
