Hello Dave,For real DC isolation you need a transformer. There are many transformer drivers like MAX845. Exactly this has 0.2A output current.Because they work with fixed frequency the circuit can be tuned for ZVS or ZCS. A small LC filter on the inp...

YEP, sorry, I found the answer. The HAL_TIMEx_ConfigCommutEvent_IT(&htim1, TIM_TS_NONE, TIM_COMMUTATION_SOFTWARE);HAS TO BE AFTER MX_TIM1_Init(); /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_TIM1_Init(); MX_ADC1_Init(); MX_TIM2_Ini...

I am trying to run a BLDC motor with TIM1 on STM32F401RE. I want to use a software commutation event with HAL drivers as is done in the "6step" examples. So far the call back is not working. Please tell me what I am missing. Thanks.
