hello ST,I’m reading about quadrature / encoder operation as would be used for positioning control of stepper motors. We use the STM32H743 in another application, and we need to determine how many channels (how many individual stepper motors) could b...

hello ST,my question is about the use of DAC with DMA on the STM32H743. I need to be able to store more tunes/tones into memory.The working code is based on an ST sample code, DAC_Ch1_EscalatorConfig(), albeit with many more samples used:HAL_DAC_Star...

dear ST / reader,our application uses the STM32H743. We need a unique serial number to be stored in this micro, in non-volatile memory, to uniquely identify each board. There’s no on-board EEPROM, so we were wondering if this device includes any inte...

Hi there,can anyone assist in understanding how to choose the correct ‘stream’ for an STM32H7 + DMA + UART setup, please ?I’m continuing work on a previous colleague’s firmware where UART1 was programmed to operate in DMA mode. This needs to change t...

Dear ST/reader,I’m currently implementing a uart receive interrupt function for use with the STM32H743 specifically using HAL_UART_Receive_IT(). This is straightforward when the receive length (number of bytes to receive) is just 1 in which case it e...
