Morgan (this is a second try at sending this message) If you can define and create the code that goes in the target PIC to support the external module that queries it, then I would be willing to create some external hardware and software to talk to the chip. I have used PICs with LCDs, serial com and more so it should be straightforward for me. I have talked to other engineers before about tethered processing. This concept assumes you have a very small kernel of logic in the target that is sufficient to investigate everything in the target system (maybe not in real time) and most of the computing burden falls on the device talking to the target [said device could be another PIC with display/keypad....or a PC or a PDA or ???] What do you think?
