Try unplugging the programmer and then writing to the PIC again. If you get the same error message - then check that the PC's connected to the programmer properly, and the obvious stuff like the serial ports enabled in the bios, and for IRQ conflicts, etc in Device Manger. If it IS connected properly - try grabbing your multimeter to make sure that the programmer is bringing up the MCLR pin properly, (Negative of the meter to GND, and the positive to MCLR. Check Microchips website for datasheets on the PIC to find the pins you need) Processing speed, type, and if it's dualed or not, doesn't matter - bit of a red herring that one. I've got to go with Lawrence on this one - sounds like a power prob..

Are either of the machines a notebook? I ask because Notebook serial ports are notoriously finicky. If neither of those, then perhaps a run down of the specs between the two machines? I personally would not think you should need a config file because the speed of the processor changed. That should be handled automatically by the programming software... This sounds more like a hardware problem. -Shawn Richard wrote: > It does work on another pc, with the same pcb that's powered in the > same way, the same programmer, the same cable ,the same psu,and the > same operating system. > > Are there any timing adjustments needed in any of the config files to > cope with differing CPU speeds?. > > Richard > > > ----- Original Message ----- > From: > To: > Sent: Friday, May 14, 2004 7:30 PM > Subject: Re: [PIC:]problems with epic programmer > > > >>I regularly get the "Code Programming error at 0000" error from the >>EPIC programmer.
