Possible to load-up a P1 program from another MCU?

Just brainstorming a concept, here.

If I have my Micromite using the P1 as a peripheral, is it possible to take a Prop program from the Micromite's SD card and load/execute it on the Prop?

    Yes - either hook your host MCU to the P1's serial pins and load through those or have it emulate an I²C EEPROM - I've seen code for both of these thing written on the Prop itself, shouldn't be difficult on another MCU, either.

    Hi

    I'm sure it must be if you get the micromite to imitate PC on serial.
    The protocol is available and I have in the past written a program in Basic (Freebasic or was it Qbasic or QB64....can't remember), that can read a file from disc and run it on the prop's ram, wasn't rocket science if I can do it so the micromite can surely do it- especially since it will not have to worry how to pulse the props reset pin.

    This is great news. Yeah I remember reading about toggling the reset and that was the worrying bit.
    Micromite BASIC is very similar to MS BASIC.

    Any idea where I can find the protocol?

    I think this is what I used
