    Red face Pic to Pic programming

    Hello Picbasic People
    i want to know any info (if this is possible?) to program the
    pic with another pic without the aid of a computer.
    i have to go to the field quite a lot to upgrade the firmware
    on instruments that uses 16f877 on board.
    although at present i use a bootloader with a laptop using
    microcode studio.
    Today i actually got on site and my laptop wouldn't work so i
    was thinking if there was a way of transfering the hex file to
    the pic from a serial eeprom
    Is this posisble?
    Any pointers on this tread would be well appreciated

    Toni,

    it should be possibe, but it will certainly take some programming.

    The more easy way is probably to use ICSP.

    check the PIC programming specs DataSheet to find out how critical timing is.

    The second option would be to write your own loader.

    This is a quite interesting project.

    Please keep us informed.
