About a year or so ago it was hard to source the ATMEGA328 chip, which is what the OpenEVSE firmware is written for. The ATMEGA644 chip was readily available and I took it upon myself to modify the code and make it work on this chip. The cool thing about the 644 microcontroller is that it has so many more IO pins available for added features. Here are my final results: https://openvolt.xyz/
