STM Nucleo Boards SPI Master/Slave Communication Problem. I set up a Nucleo-F446R as Slave Full Duplex and a Nucleo-G431R as Master Full Duplex. Master Sends -- Slave gets garbage.

The Slave Code   while (1) { //Slave Section // Check If Data is about to be received Spi3_CE_State = HAL_GPIO_ReadPin(SPI3_CE_GPIO_Port, SPI3_CE_Pin); Spi3_CS_State = HAL_GPIO_ReadPin(SPI3_CS_GPIO_Port, SPI3_CS_Pin)...
