Now that the teaching term is drawing to an end, I've had a chance to
finally build a set of words for I2C master mode on AVR and PIC24.
They're slightly different to Mike's PIC18 i2c-base words, in that some
return flags, so I've built a corresponding new set for PIC18 as well.
They're all in Forth since there doesn't seem to be much need for speed
with an I2C device. The i2c-detect word (adapted from amforth) runs on
top of this base set, with no change for all chip architectures, as does
the small application for reading a TC74 temperature sensor.
If these are of use to people, they might be included in the FF
distribution. I've tried to choose names that are similar to, but will
not clash with, the original i2c words for the PIC18.
Cheers,
Peter J.
