SPI map question

Postby ouki-wang » Thu Mar 09, 2017 3:38 am

#define PIN_NUM_MISO 25
#define PIN_NUM_MOSI 23
#define PIN_NUM_CLK 19
#define PIN_NUM_CS 22

In the spi maspter demo, espressif uses these pins. But I can not find the spi map of 25 23 19 22 in the spec. Spec IO12 IO13 IO14 IO15 mapped to HSPI.
Can any IO be mapped to SPI?

Yes sir. Almost any pin can be mapped to almost any function.... whether it be SPI, I2C, UART, RMT or other function.
