Sorry, I did not explain things very well. This C8051F350 part has an embedded 8051 processor, so it can run the PID loop and do everything the AVR can. On the downside, it will require different development tools than Arduino, but there are free 8051 compilers available (SDCC, Keil C51 eval...

This is a good question. The c8051F350 would take the place of the AVR, so it could potentially run without the RPi. But I was thinking to design the hardware such that it runs off the 5V provided from the RPi GPIO header pins, and implement the PID loop inside the RPi, so the MCU would be...

My apologies in advance for the slightly off-topic post, but I wanted to chime in with thanks to Bryan and everyone else who has contributed to this project (and say howdy to my fellow Austin-area folks). A couple of years ago I developed my own laptop-based controller using an old National...
