New board request

Title: New Board Request: ESP32-2432S024R (CYD 2.4")

Description:

I would like to request support for the ESP32-2432S024R board (Cheap Yellow Display, 2.4" version).

Board details:

Name: ESP32-2432S024R
MCU: ESP32
Display: 2.4" TFT (likely ILI9341, 240x320)
Touch controller: XPT2046
PSRAM: No
Flash size: 4MB

Additional information:
This board is very similar to the ESP32-2432S024C, ESP32-2432S028 (2.8" CYD), which is already supported. The main difference is the smaller 2.4" display.

Support might be possible with minor configuration adjustments.

I can help test firmware on this device if needed.

I can try to get a build!

I think it should be something like this.

#include "Display.h"
#include "Xpt2046Touch.h"  // ÄNDRAT: Från Cst816Touch till Xpt2046Touch 

#include <Ili934xDisplay.h>
#include <PwmBacklight.h>

// XPT2046 pins för 2432S024R
#define TOUCH_CS    GPIO_NUM_33
#define TOUCH_IRQ   GPIO_NUM_36
#define TOUCH_MOSI  GPIO_NUM_13  // Delar med display
#define TOUCH_MISO  GPIO_NUM_12  // Delar med display  
#define TOUCH_CLK   GPIO_NUM_14  // Delar med display

static std::shared_ptr<tt::hal::touch::TouchDevice> createTouch() {
    // ÄNDRAT: XPT2046 konfiguration istället för CST816
    auto configuration = std::make_unique<Xpt2046Touch::Configuration>(
        SPI2_HOST,           // Delar SPI med display
        TOUCH_CS,
        TOUCH_IRQ,
        240,                 // Bredd
        320,                 // Höjd
        true,                // Swap XY (kan behöva justeras)
        true                 // Mirror X (kan behöva justeras)
    );

    return std::make_shared<Xpt2046Touch>(std::move(configuration));
}

std::shared_ptr<tt::hal::display::DisplayDevice> createDisplay() {
    Ili934xDisplay::Configuration panel_configuration = {
        .horizontalResolution = 240,
        .verticalResolution = 320,
        .gapX = 0,
        .gapY = 0,
        .swapXY = false,
        .mirrorX = true,
        .mirrorY = false,
        .invertColor = false,
        .swapBytes = true,
        .bufferSize = LCD_BUFFER_SIZE,
        .touch = createTouch(),
        .backlightDutyFunction = driver::pwmbacklight::setBacklightDuty,
        .resetPin = GPIO_NUM_NC,
        .rgbElementOrder = LCD_RGB_ELEMENT_ORDER_BGR
    };

    auto spi_configuration = std::make_shared<Ili934xDisplay::SpiConfiguration>(Ili934xDisplay::SpiConfiguration {
        .spiHostDevice = SPI2_HOST,        // Samma SPI-host
        .csPin = GPIO_NUM_15,              // Display CS
        .dcPin = GPIO_NUM_2,               // Display DC
        .pixelClockFrequency = 40'000'000,
        .transactionQueueDepth = 10
    });

    return std::make_shared<Ili934xDisplay>(panel_configuration, spi_configuration, true);
}

[NellowTCS]

I researched a bit, and made a configuration!
Here's the build: https://github.com/NellowTCS/Tactility/actions/runs/23962358793/artifacts/6265741706

[Allexxo92]

we are getting closer I think there is something with the screen that needs to be changed.

The touch seems to work.

oh interesting!
that reminds me of another CYD haha (CYD-E32R28T): NellowTCS#4

(The screen is the wrong orientation, easy fix, and the colors are swapped for this board however)

[Allexxo92]

i got this from supplier of the board.

[NellowTCS]

Here's that build: https://github.com/NellowTCS/Tactility/actions/runs/23973178693/artifacts/6269312376
(the CI build takes ages, sorry)

[Allexxo92]

I am grateful for the help. :) i am flashing it :)

[Allexxo92]

Almost ther i think we need to calibrate the touch

[NellowTCS]

Is the text mirrored on your end too or is the image mirrored?

[Allexxo92]

No it is mirrored
And its upside down

[Allexxo92]

i think the colors are inverted to

[NellowTCS]

Those flags are so finicky :P
The colors are correct now though! (Tactility uses blue)

And for the touch, what happens if you press on the Apps icon, does Settings open? (pressing from the launcher)
And what corner do you have to press to press that X button? Top left or right? Bottom? (it'll help me see if we need to flip the touch)

[Allexxo92]

The setting icon ist a 20% to the right folder icon
