Problems setting up the library to work with ILI9488 and Arduino Nano ESP32S3

[dangerous-frog]

Hi,

I'm trying to use this library to connect an Arduino Nano ESP32S3 with a TFT touch display over ILI9488, but I can only get a white screen.

My current setup is like this:

#define USER_SETUP_INFO "User_Setup"

#define ILI9488_DRIVER

#define TFT_MISO 12
#define TFT_MOSI 11
#define TFT_SCLK 13
#define TFT_CS 2
#define TFT_DC 7 
#define TFT_RST 6 

#define TFT_BL 3

#define LOAD_GLCD   // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2  // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters
#define LOAD_FONT4  // Font 4. Medium 26 pixel high font, needs ~5848 bytes in FLASH, 96 characters
#define LOAD_FONT6  // Font 6. Large 48 pixel font, needs ~2666 bytes in FLASH, only characters 1234567890:-.apm
#define LOAD_FONT7  // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:-.
#define LOAD_FONT8  // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.

#define LOAD_GFXFF  // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

#define SMOOTH_FONT

#define SPI_FREQUENCY  40000000


#define SPI_READ_FREQUENCY  20000000

#define SPI_TOUCH_FREQUENCY  2500000

//#define USE_HSPI_PORT // The display didn't work with this uncommented either

The display works, as I can get it to work perfectly with this library https://github.com/jaretburkett/ILI9488 and this setup

#define TFT_CS         2
#define TFT_DC         7
#define TFT_LED        3
#define TFT_RST        6
// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC

The exact connections (with pin names from the display) are like this

• CLK - D13
• MOS - D11
• RES - D6
• DC - D7
• BLK - D3
• MIS - D12
• CS1 - D2
• CS2 - Nothing
• PEN - Nothing

I was able to solve this by changing the pins from the Arduino pinout to the microcontroller one. More can be found here. For example, in my code TFT_MISO 12 becomes TFT_MISO 47.

Trying to configure the Arduino Nano ESP32 with ST7796, the board keeps reseting after uploading the code...
