Hi cheetu.lee,
I recommend you to take a look to the '' SPI_FullDuplex_ComIT'' example in and compare the code there with your code. The example at this path: STM32Cube_FW_F4_V1.12.0\Projects\STM32F4-Discovery\Examples\SPI\SPI_FullDuplex_ComIT You should ensure that you are wiring correctly the connection cables. -Hannibal-
