2.8 inch 320x240 ili9341 TFT with 8/16BIT parallel interface

2.8" 320x240 ili9341 TFT with 8/16BIT parallel interface:
- 2.8-inch color screen, support 16BIT RGB 65K color display
- 240x320 resolution for clear display
- Support 8-bit/16-bit parallel bus selectable using resistor (the default is 16-bit)
- Support for touch function
- Support SD card function expansion



product page ~ LCDWiKi:2.8inch 16BIT Module ILI9341 SKU:MRB2801



It's set 16 bit by default.

To make it in 8-bit mode:
Solder R4 with 0Ω resistor or short circuit directly,
and disconnect R5.
In 8-bit data bus mode, use DB8~DB15 data pin.

Exercise:
~ Drive ILI9341 (8-bit parallel) using ESP32-S3 (ESP32-S3-DevKitC-1) in Arduino Framework
~ ILI9341 (8bit parallel bus) display on RP2040/CircuitPython
~ RP2040/CircuitPython 8.1.0 Beta 1, play animated GIF on 8 bit parallel bus ILI9341.

boochow/MicroPython-ST7735 is a modified version of GuyCarver's ST7735.py ST7735 TFT LCD driver , for micropython-esp32. This video show steps to prepare boochow/MicroPython-ST7735 driver and font files. Tested on  Espressif ESP32-C3-DevKitM-1 running MicroPython v1.19.1, to display on  1.8 inch 128x160 ST7735 SPI TFT .
