‘MCU basic current’ increases after PWM operation. - core: https://github.com/rogerclarkmelbourne/Arduino_STM32 1. If there is no operation, the total current of 0.07A flows. 2. Turn on PWM - (source code)pinMode(PA6, PWM); pwmWrite(PA6, 5000); 3. Turn off PWM - (source code)pinMode(PA6, PWM); pwmWr...
