I am just trying to do a simple SPI interface to thermocouple probe MAX6675 and I am using the example spi master code as refference.
The documentation for SPI list the pins for HSPI as
such:
https://docs.espressif.com/projects/esp ... -and-iomux
Code: Select all
#define PIN_NUM_MISO 12
#define PIN_NUM_MOSI 13
#define PIN_NUM_CLK 14
#define PIN_NUM_CS 15
https://github.com/espressif/esp-idf/bl ... ple_main.c
Code: Select all
#define PIN_NUM_MISO 25
#define PIN_NUM_MOSI 23
#define PIN_NUM_CLK 19
#define PIN_NUM_CS 22

A slap in the correct direction would be appreciated.
