Drive ILI9341 (8-bit parallel) using ESP32-S3 (ESP32-S3-DevKitC-1) in Arduino Framework
This post show how to driver 2.8" 320x240 ILI9341 TFT with 8-bit parallel
interface using
Espressif ESP32-S3-DevKitC-1, in Arduino framework, using TFT_eSPI library.
Connection:
For my 2.8 inch 320x240 ili9341 TFT with 8/16BIT parallel interface, it's set in 16-bit data bus mode 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.
Connection between Espressif ESP32-S3-DevKitC-1 and
2.8" 320x240 ili9341 TFT in 8-bit parallel interface:

ILI9341 TFT (parallel i/f)
Install TFT_eSPI in Arduino IDE's Library Manager.
Prepare user setup file, refer to Tips section in TFT_eSPI page:
If you load a new copy of TFT_eSPI then it will overwrite your setups if they are kept within the TFT_eSPI folder. One way around this is to create a new folder in your Arduino library folder called "TFT_eSPI_Setups". You then place your custom setup.h files in there. After an upgrade simply edit the User_Setup_Select.h file to point to your custom setup file.
mySetup14_ILI9341_Parallel.h, my custom setup.h file in new created "TFT_eSPI_Setups" folder.
