Hiello MTO,
Is only a beginning, I'm working on it, now i have implemented a touchscreen TFT display, the 20x4 was very poor for this application.
Basically is about challenge an ambition to do that, but on the other side i really need this tool in my workshop. Will implement charge/discharge function to integrate the current and calculate the real capacity of the battery, useful function when i have to sort the best or weakest batteries from a lot.
be back soon!
