I have successfully written an OK I2C driver that allows me to access all of the registers on the chip and started building a framework in software for collecting all that data. It has taken me a while but I have brushed up on my software skills and I am pretty confident with getting a basic working program to manage all protections and store important information on the BMS's microcontroller. I have also started work on the next board, which has a more thoroughly thought out port compliment and is about 30% smaller thanks to dropping some unneeded features and tightening up the layout. Looking forward to programming and actually getting the next revision into testing with a real battery pack.
