I am new to the STM32 microcontrollers and I am experimenting with the SPI peripheral (interrupt mode, non DMA, slave) of the STM32F410. I noticed that the reference manual mentions the SPE bit (bit 6 of the SPIx CR1 register) but does not provide mu...

Parallel transmission using GPIO and DMA (like AN4666)

Hi,I would like to send parallel byte data from STM32H743 using DMA, e. g. using Port G0...G7, using a timer to define the cycling (e. g. TIM3.CH2).For STM32L and STM32F4 this is described in AN4666 I think. I did this already on STM32F4, there it se...
