Not working with Waveshare ST7789V2 rounded display

[step135]

I use ESP32 CAM.

User_Setup.h

#define ST7789_2_DRIVER  // Use this definition for ST7789v2

// Define the display size
#define TFT_WIDTH  240     // ST7789v2 240 x 240 pixels
#define TFT_HEIGHT 280     // Change this if your display has a different resolution

// initialization sequence
#define TFT_INIT_DELAY 0x01

// Define the pins used for the display
#define TFT_MOSI  13       // Data out (MOSI)
#define TFT_SCLK  14       // Clock out (SCLK)
#define TFT_CS    15       // Chip select control pin (if used), set to -1 if not connected
#define TFT_DC    2       // Data/Command control pin (DC)
#define TFT_RST   12       // Reset pin (RST)

// Optional: Set the backlight pin if available
// #define TFT_BL   16      // Backlight control pin

// Set the SPI frequency
#define SPI_FREQUENCY  27000000 // 27 MHz (adjust as needed)

text.ino

#include <TFT_eSPI.h>   // Include the graphics library (this includes the SPI library)

// Create an instance of the display driver
TFT_eSPI tft = TFT_eSPI();  // Invoke library, pins defined in User_Setup.h

void setup() {
  Serial.begin(115200);
  Serial.println("mx TFT2 started");

  pinMode(TFT_RST, OUTPUT);
  digitalWrite(TFT_RST, LOW);
  delay(50);  // Hold reset low for 50ms
  digitalWrite(TFT_RST, HIGH);
  delay(50);  // Wait for display to reset

  tft.init();
  tft.setRotation(1); // Set display rotation

  tft.fillScreen(TFT_BLUE); // Clear the screen
  tft.invertDisplay(true);
  tft.setTextColor(TFT_WHITE, TFT_BLACK);  // Set text color to white with black background
  tft.setTextSize(2); // Set the text size

  tft.setCursor(10, 10); // Set cursor position
  tft.print("Hello World! ST7789v2"); // Print "Hello World!" on the screen

  tft.setTextSize(6);
  tft.setTextColor(TFT_RED, TFT_ORANGE);
  tft.setCursor(10, 50);
  tft.print("end");

  Serial.println("end printed on TFT");
}

void loop() {
  if(true){
  tft.init();
  tft.setRotation(0); // Set display rotation

  //tft.fillScreen(TFT_BLUE); // Clear the screen
  tft.setTextColor(TFT_WHITE, TFT_BLACK);  // Set text color to white with black background
  tft.setTextSize(4); // Set the text size
  tft.setCursor(10, 150);
  tft.print("loop");
  Serial.println("loop on TFT");
  delay(5000);
  }
}

I'm also facing a similar issue. If you have got any update on this please do share here

You could try this once, although it did not work for me!

I'm in a similar boat with an integrated ESP32-S3+ST7789V2 display. I'm trying to use Setup208_ST7789.h, as supplied from the Waveshare wiki's `product page', where the 'sample demo' download provides the libraries. I did update all of the included libraries to the latest releases.

The (not currently working) config provided by WaveShare is as follows:

#define USER_SETUP_ID 208

#ifdef USER_SETUP_INFO
#undef USER_SETUP_INFO
#define USER_SETUP_INFO "ESP32-S3-Touch-LCD-1.69"
#endif

#ifdef ILI9341_DRIVER
#undef ILI9341_DRIVER
#endif

#define ST7789_DRIVER

// For ESP32 Dev board (only tested with GC9A01 display)
// The hardware SPI can be mapped to any pins

#define TFT_WIDTH  240
#define TFT_HEIGHT 280

#define TFT_RGB_ORDER TFT_BGR

#define TFT_MISO -1
#define TFT_MOSI 7
#define TFT_SCLK 6
#define TFT_CS   5  // Chip select control pin
#define TFT_DC   4  // Data Command control pin
#define TFT_RST  8
#define TFT_BL  15
#define TFT_BACKLIGHT_ON HIGH

#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  80000000

I'd be happy to help test, or run diagnostics, if that would help.
