RGB 480x272 Timing setup

[ChubbyBunny1]

Hello, i have this LCD https://www.tme.eu/Document/35eef2eefcc4d29f834ebf8192b0cb7d/DEM480272QVMX-PWN.pdf and i need some help configuring the RGB Bus. Here is my code but it doesnt seem to work. Using ESP32-S3-WROOM-1

      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_d11 = GPIO_NUM_14; // R0
      cfg.pin_d12 = GPIO_NUM_21; // R1
      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 = 8000000; 

       cfg.hsync_polarity = 1;
      cfg.hsync_front_porch = 8;
      cfg.hsync_pulse_width = 4;
      cfg.hsync_back_porch = 43;

      cfg.vsync_polarity = 0;
      cfg.vsync_front_porch = 8;
      cfg.vsync_pulse_width = 4;
      cfg.vsync_back_porch = 12;

      cfg.pclk_active_neg = 1; 
      cfg.de_idle_high = 0;
      cfg.pclk_idle_high = 0;

hi,

please edit your post and provide the full configuration class, also add more precision to what you tried and the results you had.

Hi @ChubbyBunny1 did you make it work?
