+These displays use 8-bit parallel to communicate, 12 or 13 pins are required to interface (RST is optional). This library supports 8-bit and 16-bit parallel TFT displays on AVR (ATmega328/32u4/1280/2560) and the Arduino Due (SAM3X8E) only. It does not support ESP32, ESP8266, SAMD or RP2040 boards. For parallel displays on ESP32-S3, see the LCD_CAM peripheral and a library that drives it.
