Hello people.

With my students we're trying to make a simple payload for a balloon
experiment. One of the parts is an f873a which will receive commands
through i2c. It has all its other pins occupied so I wanted to implement
a bootloader through the i2c to make development easier.

I've tried to modify microchip's boot serial loader by changing the
comm routines into i2c ones (also based on an appnote). Reception seems
to work, transmission doesn't.

I wonder if anyone has an i2c bootloader laying around, or maybe just
some code which uses the MSSP in non-interrupt i2c-mode. Or
just any suggestion where to look would be welcome. I think I visited
most of the googgle's knowledge on the issue.

I could post the code I have, but it's a bit long...

Thanks in advance,
John
