Troubleshooting SPI Communication Between STM32G431RB Master and F446RE Slave Boards
I am trying to establish communication between two Nucleo boards (STM32G431RB as master and Nucleo F446RE as slave). I used the example codes from the STM32 GitHub page (NUCLEO-G431RB/Examples/SPI/SPI_FullDuplex_ComPolling_Master and STM32F411RE-Nucleo/Examples_MIX/SPI/SPI_FullDuplex_ComPolling). I made some changes to the slave code, including GPIO settings, but the communication still doesn't work. I chose NSS as [ hspi1.Init.NSS = SPI_NSS_SOFT; ]. The codes also include LED configurations as mentioned in the README files, which indicate an error based on the LED status.I know I have an error acording to led 2 but I don't know the problem.
LED2 toggles slowly when there is a timeout or an error in transmission/reception process.
