This week I made progress on the raspberry pi i2c code. I started by having a usable GPIO version of the pi code to demo, showing the design of the transmission protocol. Since the demos, I have made progress into using i2c. Since our PCB development is running behind, I decided to use an arduino from home as a PCB emulator until the PCB arrives. The polling rate will likely be much worse, but in the worst case we should still be able to put a product together. Furthermore, this should allow me to develop the Pi-side code enough to quickly implement once the PCB arrives.
