Problems with spi_lcd_touch_example (IDFGH-14945)

[ManelCS]

I'm trying to follow this example
https://github.com/espressif/esp-idf/tree/master/examples/peripherals/lcd/spi_lcd_touch
with a ESP32-s3 and the display NHD-2.4-240320AF-CSXP but I only see the backlight on the screen. The connection is:

#define EXAMPLE_LCD_PIXEL_CLOCK_HZ (15 * 1000 * 1000)
#define EXAMPLE_LCD_BK_LIGHT_ON_LEVEL 1
#define EXAMPLE_LCD_BK_LIGHT_OFF_LEVEL !EXAMPLE_LCD_BK_LIGHT_ON_LEVEL
#define EXAMPLE_PIN_NUM_SCLK 14 // tft dcx
#define EXAMPLE_PIN_NUM_MOSI 47 // tft sda
#define EXAMPLE_PIN_NUM_MISO 38 // tft sdo
#define EXAMPLE_PIN_NUM_LCD_DC 11
#define EXAMPLE_PIN_NUM_LCD_RST 12 // tft resx
#define EXAMPLE_PIN_NUM_LCD_CS 45 // tft csx
#define EXAMPLE_PIN_NUM_BK_LIGHT 4
#define EXAMPLE_PIN_NUM_TOUCH_CS -1

also i change the line
ESP_ERROR_CHECK(esp_lcd_new_panel_ili9341(io_handle, &panel_config, &panel_handle));
for
ESP_ERROR_CHECK(esp_lcd_new_panel_st7789(io_handle, &panel_config, &panel_handle));

I'm not familar with NHD-2.4-240320AF-CSXP, but from the picture, I don't know why you connect the "DCX" to the "SCL"? "SCL" is the SPI clock signal. "DCX" is the "Data/Command selection".

If you post such questions in the ESP32 Forum, you will get more help :)

The picture is from the datasheet of the display I use:
