    Default MAX232, Bootloader, Microchipc test prints garbage

    Hi there,
    I'm trying to setup my p16f876 w/ a MAX232CPE and then use microchipc's bootloader ( http://www.microchipc.com ). I have wired the MAX232/876 with 6 different schematics but it still prints garbage with a simple test file on hyperterm or other terminal program - I'm pretty sure the wiring is ok.
    I tried skipping the [failed] test anyway and programming the bootloader with my programmer. The bootloader loads OK but the bootloader program (through the max232) still hangs while seeking the bootloader, indicating a serial problem.

    PIC16f876
    20Mhz crystal
    Max232CPE
    Microcode Studio and Hyperterm
    I've tried all baud rates and crystal speeds allowed in the test files and on the terminal programs.

    Is anybody using Microchipc's bootloader / test program successfully?

    I assume you are using Microcode Studio Lite. Why not upgrade to the bought version. You will then be able to use it's built in bootloader which works flawlessly.

    I ordered it after another hour of futzing around with a different freeware bootloader. You get what you pay for.

    MCS+ and it's bootloader worked fine with the same wiring. I made it a point to keep the same wiring and It has been great.
    You get what's promised and what you pay for with MCS+!
