STM32H743 SPI Master works fine... problem is it should fail :) Hello, the problem here is that SPI works :) I am successfully using SPI on my STM32H743 MCU for many years now.Now I encountered the problem with the same code, the same configuration of SPI but the difference is that the slave SPI chip is not there ( a new module with the same chip is not yet assembled). I am running the same code to debug something else , yet this SPI communication returns HAL_OK ! No timeout!I never had this before ('cause I always had my slave chip connected) . The HAL_SPI_TransmitReceive() function of SPI library still returns HAL_OK :)Here is a fragment of my code (SPI configured duplex master, data 16-bit, FIFO =1, speed 1.875 MBits/s, software driving CS) :Spi4NSSEn; // chip select enabled// addr_cmd[] provides 2 addresses for 2 channels of ADC converter// pots_bin is a buffer for the ADC result in 0-256 range of POT sweepif(HAL_SPI_TransmitReceive(&pots_hspi, (uint8_t *)addr_cmd, (uint8_t *)pots_bin, 2, 5000) != HAL_OK ) // transmit and receive 2 dat
