Create an STM32 firmware module that reads battery current via ADC (INA219 or shunt resistor) and integrates over time (coulomb counting). Track total charge in/out per cycle. Publish battery_state with voltage, current, percentage (based on coulomb count vs rated capacity), and cycle count. Store calibration in flash. Single C file: src/battery_coulomb.c + header.
