ESP32 SD Card Interfacing Fast!

First we'll make a free SD Card module, then setup the ESP32 boards in the Arduino IDE and finally program our board to use an SD Card with the slow SPI and much faster MMC interfaces. More info on setting up the Arduino IDE in case I went too fast: https://circuitdigest.com/microcontroller-projects/programming-esp32-with-arduino-ide The original Reddit post that helped ALOT with getting MMC to work (unfortunately the original poster deleted their account so I can't credit them): https://www.reddit.com/r/esp32/comments/d71es9/a_breakdown_of_my_experience_trying_to_talk_to_an/ ESP32 SPI Driver info: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/sdspi_host.html ESP32 MMC Driver info: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/sdmmc_host.html
