IO_MUX and CS pin
Posted: Wed Apr 22, 2020 4:33 pm
hello,
I would like to use the fastest SPI interface possible, so I am using these pins to take advantage of the IO_MUX
[Codebox]#define PIN_NUM_MISO 12
#define PIN_NUM_MOSI 13
#define PIN_NUM_CLK 14
#define PIN_NUM_CS 15[/Codebox]
But am I really forced to use the CS pin or can I use everything? In other architecture I am free to use any pin for the CS
