Before I recently got back to working on my car I was continuing work on my BMS. A lot has changes since my first revision and I will try too go over all that here. First off and most noticeably is I have created an actual PCB, this is a huge improvement over the previous breadboard design as I can now develop on the hour long train ride to work.
I do however need to make a second rev of the board to fix some little bugs, remove some unnecessary components and move some connectors around. Since my previous version of the BMS master board I have also switched to a big beefy 32bit PIC microcontroller, this meant rewriting my menu code. I also took the opportunity to write some line and circle drawing routines.
