Real Time Operating System implemented for STM32

C99 firmware core for a 16-series LFP pack. Independent charge and discharge FETs, cell protection, coulomb SOC, and the current and voltage limits an inverter follows. Passive balance runs for 1.0 s, then 200 ms off, so the fault wait finishes on an unloaded sample. No RTOS, no heap. The AFE driver and fieldbus stay on your board.
