Hello, I am working on a full duplex SPI communication through DMA using STM32H7. So, I have bought 2 NUCLEO-H743ZI, one to be the master, the other to be the slave. I have downloaded, built and flashed SPI_FullDuplex_ComDMA example via TrueStudio. As there is no ''TrueStu...
I have only the one Nucleo, so I compiled the project SPI_FullDuplex_ComDMA set as master. This example is intended to transmit a message from one board as a master to another board as a slave. Since I don't have another board, I simply scoped the SCK pin and I see nothing when ...

3.21 Serial peripheral interface (SPI) The device contains two SPIs running at up to 32 Mbits/s in master and slave modes. It supports half-duplex, full-duplex and simplex communications. A 3-bit prescaler gives eight master mode frequencies. The frame size is configurable from 4 bits to ...
