Arduino nano esp32 lcd ILI9341 now work

[wolfwood1010]

I tried to connect the display with ILI9341 controller to arduino nano esp32 using the following pins

in the library TFT_eSPI. I configured User_Setup.h as follows

#define ILI9341_DRIVER

#define TFT_CS   10  // GPIO 10 (D10)
#define TFT_DC   9   // GPIO 9 (D9)
#define TFT_RST  8   // GPIO 8 (D8)
#define TFT_WR   11  // GPIO 11 (D11)
#define TFT_RD   12  // GPIO 12 (D12)

#define TOUCH_CS 5   // GPIO 5 (D5)

#define SPI_FREQUENCY  27000000
#define SPI_TOUCH_FREQUENCY  2500000

and try next sketch

#include <TFT_eSPI.h>
#include <SPI.h>


#define TFT_CS   D10
#define TFT_DC   D9
#define TFT_WR   D11
#define TFT_RD   D12
#define TFT_RST  D8

TFT_eSPI tft = TFT_eSPI();

unsigned long previousMillis = 0;
const long interval = 1000; 

void setup() {
  
  Serial.begin(115200);

  tft.init();
  tft.setRotation(1);
  tft.fillScreen(TFT_BLACK);
  tft.setTextColor(TFT_WHITE, TFT_BLACK);
  tft.setTextSize(2);
  tft.setCursor(0, 0);
  tft.println("Hello, World!");
}

void loop() {
  unsigned long currentMillis = millis();
  if (currentMillis - previousMillis >= interval) {
    previousMillis = currentMillis;
    
    tft.fillScreen(TFT_BLACK);
    tft.setTextColor(TFT_WHITE, TFT_BLACK);
    tft.setTextSize(2);
    tft.setCursor(0, 0);
    tft.println("Hello, World!");
  }
}

but it didn't work and on startup there was a white tap after just black, on the arduino module lights 3 LEDs near the usb green and yellow and near the reset there was a red

At first glance, that appears to be a parallel interface display, not SPI. So you can't use an SPI library to control it. The WR and RD pins are likely control signals to gate out or in a 16 bit word to/from the display, not MOSI and MISO signals.

Should there be SPI.h and TFT_eSPI.h ?

In Tools have you selected Arduino (default) or GPIO (legacy) Pin Numbering ?

I took those to be for touchscreen.

Yes, apparently I made a mistake on the manufacturer's website I found the following information
