    Default In-circuit Programming.

    Good day Picers

    I have always done my programming with the Microchip picstart plus for DIP PICs.

    I want to do In-circuit programming on SMD PICs now.
    What are the best options?
    I see Microchip have a "MPLAB REAL ICE" and the "MPLAB ICD 2".
    Are these the best programmers to use and what else do I need.
    Do I need any changes on my circuit side?

    Thank you

    Hi, Koossa

    Depends on the pinouts you use ... but 3M builds "pinthrough" test chip carriers for SMD devices ... just build an adaptator to suit you need. ( to buy from Farnell i.e.)

    Microchip also sells ready to use adaptators ...

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    Thank you for your reply.
    I want to program my SMD Pic while it is in the circuit.
    I'm not that clued up with this stuff, but what will the adaptor do?

    So,

    ICD2 from Microchip
    PicFlash2 from Mikroelektronika ...

    are the ones I would recommend.

    Thank you very much!!

    Do I need any modifications on my circuit if I move over to in-circuit programming?

    The ICSP used pins must be disabled from your circuitry just for programming ... you re-enable those PCB tracks after programming by using jumpers or, simpler by tin drops on the PCB side.

    see here :

    http://www.mikroe.com/pdf/picflash_manual_v5.pdf

    It's the clearest document I know ...
