Hi Leonardo,
you can use a custom SPI interface with the relative pin

/*
Default SPI
  #define HSPI_MISO   12
  #define HSPI_MOSI   13
  #define HSPI_SCLK   14
  #define HSPI_SS     15

*/

SPIClass * hspi = NULL;
 
void setup() {
   hspi = new SPIClass(HSPI);
 
  //        sck, miso, mosi, ss
   hspi->begin(HSPI_SCLK, HSPI_MISO, HSPI_MOSI, 16);
 }

In the example, I use the same SPI pin but a dedicated CS for activation.
I didn’t test It but I think It’s ok.

As you can see in the pinout on the same SPI pins there is the SD.

Hi Leonardo,
GPIO15 is the standard CS, and it’s used for SD, so you must change it.
