Hi all, Still going with the PicPocket programmer. 6K of code now. I was going to implement a small FAT system, but not sure if its worthwhile at this stage. The chips are flash, so upgrading should be a snap anyway. It now has user set verification voltages from 2V to 6V in 0.25V steps and can be easily calibrated at anytime by the user. I have an interface for the ICSP ready(?), but a few questions if anyone can help. The PIC's are supposed to be programmed with VccP at 5V, but can be verified afterwards at lower or higher voltages. How would this affect a target circuit that is designed to run on 2V? Is the ISCP supposed to power the target circuit? I've got ~200 mA available. Should these problems be addressed by the target circuit designer?
