WebSep 13, 2024 · 1 I'm still doing SPI experiments between two Nucleo STM32H743 boards. I've configured SPI in Full-Duplex mode, with CRC enabled, with a SPI frequency of 25MHz (so Slave can transmit without issue). DSIZE is 8 bits and FIFO threshold is 4. On Master side, I'm sending 4 bytes then wait for 5 bytes from the Slave. outback lunch special coupon
