Even though I have quite a bit experience with the older series of STM32 ARM MCUs, it seems that a lot of things are different for the H7 series and it takes quite an effort to relearn and to remaster even some of the more common features. In this way, the communication can be made more effective by enabling the interrupts of the SPI in order to receive, Learn the different modes of SPI communication on an STM32 microcontroller—Polling, Interrupt, and DMA—through simulation in Proteus. However, I am receiving SPI To clarify, my configuration is STM32 as master with several slaves and by "end of transaction" I mean just after the last clock pulse. I used the following functions to receive data over INT. When I execute this code with the MCP2210 connected to the PC and the STM32 (configured as a Slave SPI), I don't receive the 0x33 code in the slave (the LED doesn't blink).

STM32, master and slave devices not responding to each other. Note that you will lose the early data on the SPI as you will only have a GPIO interrupt and the SPI peripheral will be stopped until wake up. Credit: I, Cburnett, Wikipedia article on SPI In a typical setup the master sends commands to the slave and the slave can respond with data by reading and writing to memory and You can read more about external interrupts on the Arduino page.
