Program 3 PICs using one PICKIT 3. Possible?

[BobEdge]

Thank you all for the replies.
This is an industrial product, so not worth taking the risk.
I admit I had not thought about the verify part of programming.

Regards
Bob.

Hi Bob. I mentioned this in another post a while back. I have programmed 10 PICs at once for use in commercial products BUT the products were tested before releasing them. Simply stack one PIC on top of each other so that all the pins are in parallel and all will program. If you stack say 6 and the 4th one up isn't connected then the chain is broken and 4,5 and 6 won't be programmed. Try it, it works.

Keep in mind that Pickit is not for production as Microchip states and as I have confirmed.

From times to times I had chips that were not programmed 100% correctly.

With other programmers like ICD3 or Elnec Pikprog+ never had a problem of corrupt code.

I second this; never had a problem. Been cascading chips like this since the good old 27XX EPROM days.
