Re: SPI does not work
Hi, I have resolved the issue. I have noticed that mosi_io_num and data0_io_num are union. Also miso_io_num and data1_io_num. union { int mosi_io_num; ///< GPIO pin for Master Out Slave In (=spi_d) signal, or -1 if not used. int data0_io_num; ///< GPIO pin for spi data0 signal in quad/octal mode, or...

SPI does not work
Hello, I have got XIAO ESP32S3 and ESP32-WROOM32 units. I have got exactly the same problem on both. SPI works on Arduino but it does not on ESP-IDF. I use ESP-IDF 5.1.2. I setup SPI by using code below. Later I send 4 bytes //On XIAO I tried //gpio_iomux_in(GPIO_NUM_9, SPI3_D_IN_IDX); //gpio_iomux...
