Needed to add the following flags to the bus config to get SPI working on desired IO pins
Code: Select all
.flags = SPICOMMON_BUSFLAG_MASTER | SPICOMMON_BUSFLAG_GPIO_PINS | SPICOMMON_BUSFLAG_SCLK | SPICOMMON_BUSFLAG_MOSI | SPICOMMON_BUSFLAG_MISO

ESP-IDF SPI not working but equivilant code working with arduino IDE code
I have a ESP32-S3-DevkitC-1 and am trying to get spi running in master mode with spi pins assigned to the following GPIOs
#define PIN_NUM_MISO GPIO_NUM_9
#define PIN_NUM_MOSI GPIO_NUM_12
#define PIN_NUM_SCLK GPIO_NUM_11
#define PIN_NUM_nSCS GPIO_NUM_10
I have got this running with a simple arduino ...
#define PIN_NUM_MISO GPIO_NUM_9
#define PIN_NUM_MOSI GPIO_NUM_12
#define PIN_NUM_SCLK GPIO_NUM_11
#define PIN_NUM_nSCS GPIO_NUM_10
