support for esp32-2432s022c board

[cosmos1978]

I recently bought some of these screens (ESP32-2432s022c)

I tried configuring it based on your github but I only am able to get some distorted images on the display. ( snow pattern ) It uses ST7789 driver and the same touch driver as your board. The difference is that the tft display uses an 8 bit parallel bus. It also needs to use lovyanGFX since it uses pin's above 31

I have some sample code that runs perfect on the board. And I tried to map the pins like in that code but I am stuck now on this distorted image

Perhaps you have some ideas on how to get it working ?

below is the working arduino code and the platformio.ini env I created based on https://github.com/elik745i/ESP32-2432s024c since he was able to include support for the touch chipset

public: LGFX(void) { { auto cfg = _bus_instance.config(); cfg.freq_write = 25000000; cfg.pin_wr = 4; cfg.pin_rd = 2; cfg.pin_rs = 16;

    cfg.pin_d0 = 15;
    cfg.pin_d1 = 13;
    cfg.pin_d2 = 12;
    cfg.pin_d3 = 14;
    cfg.pin_d4 = 27;
    cfg.pin_d5 = 25;
    cfg.pin_d6 = 33;
    cfg.pin_d7 = 32;

    _bus_instance.config(cfg);
    _panel_instance.setBus(&_bus_instance);
}

{
    auto cfg = _panel_instance.config();

    cfg.pin_cs = 17;
    cfg.pin_rst = -1;
    cfg.pin_busy = -1;

    cfg.panel_width = 240;
    cfg.panel_height = 320;
    cfg.offset_x = 0;
    cfg.offset_y = 0;
    cfg.offset_rotation = 0;
    // cfg.dummy_read_pixel = 8;
    // cfg.dummy_read_bits = 1;
    cfg.readable = false;
    cfg.invert = false;
    cfg.rgb_order = false;
    cfg.dlen_16bit = false;
    cfg.bus_shared = true;

    _panel_instance.config(cfg);
}

setPanel(&_panel_instance);

} };

I second this request

[cafalchio]

same issue, not sure which are the correct pins

[Panaceabeachbum]

Same here, any help appreciated

[Panaceabeachbum]

Is there a pinout available for this particular board? I have no problem finding a get started pdf for a number of their other boards but not this one

Somebody seems to have a platformio config for this very board. https://github.com/rzeldent/platformio-espressif32-sunton/blob/main/esp32-2432S022C.json

Probably this could be used in some fashion in this project.
