SD library

This library provides the integration of ESP32 and SD (Secure Digital) cards without additional modules.

- Warning: Some ESP32 modules have different pinouts!

FAQ:

Do I need any additional modules, like Arduino SD module?

No, just wire your SD card directly to ESP32.

What is the difference between SD and SD_MMC libraries?

SD runs on SPI, and SD_MMC uses the SDMMC hardware bus on the ESP32.

Can I change the CS pin?

Yes, just use: SD.begin(CSpin)
