There are four DC fans connected the board.  For each, there is a current resistor buffered through an op-amp and then passed to the ADC channel on the STM32G491RET6 MCU. All four ADCs are connected to the same module on four different channels. Soft...

MCU: STM32G491RET6 Due to other pins being unavailable, I am trying to use TIM8_CH3N to generate a PWM output. To test this, I used CubeMx to generate configuration code for me, and only added the line to start PWM:HAL_TIM_PWM_Start(&htim8, TIM_CHANN...
