NRF52832 SPI receives the first byte as 0xFFhttps://devzone.nordicsemi.com/f/nordic-q-a/85377/nrf52832-spi-receives-the-first-byte-as-0xffI use SPI to develop motion sensors KX022 and DW1000. The first digit of the received data is always 0xFF. If the first byte received is removed, it can be used normally. I want to know what caused this. The results are the same with or without EasyDMAen-USTelligent Community 13Thu, 03 Mar 2022 09:10:20 GMTRE: NRF52832 SPI receives the first byte as 0xFFhttps://devzone.nordicsemi.com/thread/355960?ContentTypeID=1Thu, 03 Mar 2022 09:10:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d3c5bb0e-7478-4483-9fcf-5f6700f46825Turbo J<p>Expected behavior, the readback on the command byte is a dummy (= not valid). I believe there are SPI communication examples in the datasheets.</p><div style="clear:both;"></div>
