Hello @klita
We recommend to use LovyanGFX library as drive. Please find the following code for the display configuration:

         #include <LovyanGFX.hpp>
        #include <lgfx/v1/platforms/esp32s3/Panel_RGB.hpp>
        #include <lgfx/v1/platforms/esp32s3/Bus_RGB.hpp>

        #define TFT_BL 2

        class LGFX : public lgfx::LGFX_Device {
        public:
          // Instances for the RGB bus and panel.
          lgfx::Bus_RGB     _bus_instance;
          lgfx::Panel_RGB   _panel_instance;

          // Constructor for the LGFX class.
          LGFX(void) {
            // Configure the RGB bus.
            {
              auto cfg = _bus_instance.config();
              cfg.panel = &_panel_instance;

              // Configure data pins.
              cfg.pin_d0  = GPIO_NUM_15; // B0
              cfg.pin_d1  = GPIO_NUM_7;  // B1
              cfg.pin_d2  = GPIO_NUM_6;  // B2
              cfg.pin_d3  = GPIO_NUM_5;  // B3
              cfg.pin_d4  = GPIO_NUM_4;  // B4

              cfg.pin_d5  = GPIO_NUM_9;  // G0
              cfg.pin_d6  = GPIO_NUM_46; // G1
              cfg.pin_d7  = GPIO_NUM_3;  // G2
              cfg.pin_d8  = GPIO_NUM_8;  // G3
              cfg.pin_d9  = GPIO_NUM_16; // G4
              cfg.pin_d10 = GPIO_NUM_1;  // G5

              cfg.pin_d13 = GPIO_NUM_47; // R2
              cfg.pin_d14 = GPIO_NUM_48; // R3
              cfg.pin_d15 = GPIO_NUM_45; // R4

              // Configure sync and clock pins.
              cfg.pin_henable = GPIO_NUM_41;
              cfg.pin_vsync   = GPIO_NUM_40;
              cfg.pin_hsync   = GPIO_NUM_39;
              cfg.pin_pclk    = GPIO_NUM_0;
              cfg.freq_write  = 15000000;

              cfg.vsync_polarity    = 0;
              cfg.vsync_front_porch = 1;
              cfg.vsync_pulse_width = 31;
              cfg.vsync_back_porch  = 13;

              // Configure polarity for clock and data transmission.
              cfg.pclk_active_neg   = 1;
              cfg.de_idle_high      = 0;
              cfg.pclk_idle_high    = 0;

              // Apply configuration to the RGB bus instance.
              _bus_instance.config(cfg);
            }

            // Configure the panel.
            {
              auto cfg = _panel_instance.config();
              cfg.memory_width  = 800;
              cfg.memory_height = 480;
              cfg.panel_width   = 800;

              cfg.offset_x      = 0;
              cfg.offset_y      = 0;

              // Apply configuration to the panel instance.
              _panel_instance.config(cfg);
            }

            // Set the RGB bus and panel instances.
            _panel_instance.setBus(&_bus_instance);
            setPanel(&_panel_instance);
          }
        };
        LGFX lcd;

I compiled and loaded this and nothing displayed.
I put it all within void setup() { } and a blank
void loop() { }
My goal is a basic "shell" or beginning portion that activates the display so I can continue with various programs of my own with it.
Help appreciated.. regards Bo W4GHV since 1954
