Drive 320x240 ILI9341 SPI TFT using ESP32-S3 (NodeMCU ESP-S3-12K-Kit) using TFT_eSPI library, in Arduino Framework.

Drive 2.4 inch 320x240 ILI9341 SPI TFT on Ai-Thinker NodeMCU ESP-S3-12K-Kit using TFT_eSPI library, in Arduino Framework.

The steps same as in my former post "Drive ILI9341 (8-bit parallel) using ESP32-S3 (ESP32-S3-DevKitC-1)", with custom user setup for SPI ILI9341 driver.

The custom user setup I modify from is Setup70b_ESP32_S3_ILI9341.h (inside your local installed library folder or here), copy it to the new created "TFT_eSPI_Setups" folder, rename as mySetup70b_ESP32_S3_ILI9341.h.

For SPI connection, I follow the original assignment.

For DC and RST pins, the original assigned pins (GPIO 7 and 6) are connected to LEDs in NodeMCU ESP-S3-12K-Kit (ref: ESP-S3-12K-Kit Schematic), so I re-assign to GPIO 16 and 15).

mySetup70b_ESP32_S3_ILI9341.h

// Setup for the ESP32 S3 with ILI9341 display
// Note SPI DMA with ESP32 S3 is not currently supported
#define USER_SETUP_ID 70
// See SetupX_Template.h for all options available
#define ILI9341_DRIVER

                    // Typical board default pins - change to match your board
#define TFT_CS   34 //     10 or 34 (FSPI CS0) 
#define TFT_MOSI 35 //     11 or 35 (FSPI D)
#define TFT_SCLK 36 //     12 or 36 (FSPI CLK)
#define TFT_MISO 37 //     13 or 37 (FSPI Q)

/*

#define SPI_READ_FREQUENCY  6000000 // 6 MHz is the maximum SPI read speed for the ST7789V

#define SPI_TOUCH_FREQUENCY 2500000

Edit the User_Setup_Select.h file to point to the custom setup file.

//#include <User_Setup.h>           // Default setup is root library folder
#include <../TFT_eSPI_Setups/mySetup70b_ESP32_S3_ILI9341.h>
