ESP32-SPI

Some SPI related notes...

Wires to connect SPI SD/TF card

Use ESP32's VSPI , works on Arduino SdFat library
   

 



Widora-Air SdFat notes:

• Change SPI pins in SdSpiDriver.h: SPI.begin(18,19,23); //Change to VSPI
  
• Select the correct SPI SS pin: SD_CHIP_SELECT = 5;
  
• Change SPI Speed from 50MHz to 25MHz: if (!sd.cardBegin(SD_CHIP_SELECT, SD_SCK_MHZ(25))) { //works under 25MHz
