Parallax Propeller and Atmega168 (on an STK500) trying to play nice together.
The STK500 with the Atmega168 on it is meant to emulate an Arduino, but I need a level adjuster on the TWI/I2C lines. The Arduino runs, nominally, at 5v, but the Propeller runs at a nice and sensible 3.3v. The only way to really emulate an Arduino in the circuit (prior to getting a level adjuster that'll manage the different potentials) is to plop the Atmega168 in there, adjust the voltage of the STK500 to 3.3 and upload to the STK500 the .hex files the Arduino IDE generates. It's an annoying tool chain.
