Problem getting custom board with esp32-s3-r8n16 and ST7789 display running

[ffppmm]

Hi,

can anybody help me with the correct User_Setup.h for the board? I got the Arduino_gfx library running with the board to find the correct settings for the pins. If I configure the same in tft_eSPI in User_Setup.h the display doesn't show anything, for example with the Colour_test sketch :(

Any ideas what "is wrong" with my settings?

I'm using:

#define USE_HSPI_PORT

So its not a crash loop, I checked the serial console.

Regards Philipp

code working with Arduino_GFX:

#include <Arduino_GFX_Library.h>

#define TFT_BL 14  // Back-light GPIO

// ---- Display bus and driver ----
Arduino_DataBus *bus = new Arduino_ESP32SPI(
  11 /* DC */,
  10 /* CS */,
  12 /* SCK */,
  13 /* MOSI */,
  GFX_NOT_DEFINED /* MISO not used */
);
Arduino_GFX *gfx = new Arduino_ST7789(
  bus,
  1,            // RST (some boards ignore this)
  1,            // rotation
  true,         // IPS
  170, 320,     // width, height
  35, 0, 35, 0  // column/row offsets
);

void setup() {
  pinMode(TFT_BL, OUTPUT);
  digitalWrite(TFT_BL, HIGH);  // turn back-light on

  gfx->begin();
  gfx->fillScreen(BLACK);
  gfx->setTextColor(RED);
  gfx->setTextSize(3);
  gfx->setCursor(10, 40);
  gfx->println("Hello!");
  delay(1000);

  // Color sweep
  gfx->fillScreen(RED);
  delay(500);
  gfx->fillScreen(GREEN);
  delay(500);
  gfx->fillScreen(BLUE);
  delay(500);
  gfx->fillScreen(YELLOW);
  delay(500);
  gfx->fillScreen(BLACK);
  gfx->setTextColor(CYAN);
  gfx->setCursor(10, 80);
  gfx->println("Screen OK!");
}

void loop() {}

My current User_Setup.h that is not working, for example with the Colour_Test sketch:

TFT_eSPI ver = 2.5.43
Processor    = ESP32
Frequency    = 240MHz
Transactions = Yes
Interface    = SPI
Display driver = 7789
Display width  = 170
Display height = 320

R0 x offset = 34
MOSI    = GPIO 13
SCK     = GPIO 12
TFT_CS   = GPIO 10
TFT_DC   = GPIO 11

TFT_BL           = GPIO 14

Smooth font enabled

Display SPI frequency = 27.00

TFT_ReadWrite_Test sketch always gives an ERROR:

Pixel value written = 1
 Pixel value read    = 0
 ERROR                 ^^^^
 Pixel value written = 2
