Hi, I want to configure my TIM1 to use it for driving a bldc motor. I have made several configuration in the registers, but it won't work. TIM1_CR1bits.CEN = 0; //Timer enable TIM1_CR1bits.DIR_= 0; TIM1_CR1bits.CMS = 0b01; TIM1_...

How to get the STM32F7 CAN peripheral out of passive mode

I have several slave devices devices hanging off connected to an STM32F7. When I power cycle the slave devices, the REC field in the ESR is greater than 128, causing the EPBF bit (in passive mode) to also be set. If I reload the chip, ESR is cleare...
