ESP32 is a series of low cost, low power system on a chip microcontrollers with integrated Wi-Fi & dual-mode Bluetooth. While it would be nice to have it as a part of core, since it is a native peripheral, if it is not maintained there, it is not nearly as useful as a community project. The library currently supports the ILI9341, ILI9163, ST7735 and S6D02A1 based TFT displays with SPI interface. ESP32¶ The ESP32 provides two channels of SD/MMC hardware and also supports access to SD Cards through either of the two SPI ports that are generally available to the user. h library to read, write, modify files • DIY Projects How to read write update files with the SPIFFS. ESP32 boots from SPI flash. The build output will then need to be downloaded to the ESP32 system flash memory. The master is the active part in this system and has to provide the clock signal a serial data transmission is based on. Using the MFRC522 Library by @sahand_123 works fine, but it only reads from the first channel. Electronics and software I made for Arduino and ESP8266/ESP32 boards. If you add a library in the future, do NOT click Install in PlatformIO’s library management.

I moved away from the Arduino IDE and just went straight to ESP-IDF using Arduino-ESP as a component. Installing SSD1306 OLED Library - ESP32.
