Hi,I'm using STM32G474 to drive my BLDC motor, i want to trig low-side phase current sensing ADC when the lower MOSFET is conducted. But the wired thing is even though CMP2 callback did be called by interrupt, ADC also not triggered (ConvCpltCallback...

Hi， I'm using STM32G431 to drive my SPI screen. Due to the high cpu load, i decided to change the IT sending mode to DMA. After putting a little changes on code, it doesn't work any more, and i have confirmed it will work again once get it back to IT...

See DS13560 Rev 4 (Datasheet of STM32G0B1RE)please. On the right side, it said "Six USARTs with master/slave synchronous SPI; three supporting ISO7816 interface, LIN, IrDA capability, auto baud rate detection and wakeup feature". I'm now writing cour...

Hi,The hspi->ErrorCode = 0x20, which told /*!< Error on RXNE/TXE/BSY/FTLVL/FRLVL Flag */. Then, SPI_SR = 0x82, so BSY and TXE was set.I'm using FreeRTOS so, the thread will block untill TxCpltCallback send signal to it.

SPI DMA cannot send multiply bytes

Feel confused about "USART with SPI" in datasheet of STM32G0B1RE
