also this is the code for how i implemented the button press with encoder

// Encoder read function
void encoder_read(lv_indev_drv_t *drv, lv_indev_data_t *data) {
    long newPosition = M5Dial.Encoder.read() / 4; // Normalize encoder position
    if (newPosition != oldPosition) {
        int encoderDiff = newPosition - oldPosition;
        oldPosition = newPosition;

        // React to encoder rotation
        if (encoderDiff > 0) {
            lv_group_focus_next(group);
        } else if (encoderDiff < 0) {
            lv_group_focus_prev(group);
        }
    }

    // Check button press
    if (M5Dial.BtnA.wasPressed()) {
        data->state = LV_INDEV_STATE_PR;
        Serial.println("M5.BtnA Pressed");
    } else {
        data->state = LV_INDEV_STATE_REL;
    }
}

// Display flush function
void my_disp_flush(lv_disp_drv_t *disp, const lv_area_t *area, lv_color_t *color_p) {
    uint32_t width = (area->x2 - area->x1 + 1);
    uint32_t height = (area->y2 - area->y1 + 1);

    M5.Display.startWrite();
    M5.Display.setAddrWindow(area->x1, area->y1, width, height);
    M5.Display.pushPixels((uint16_t *)&color_p->full, width * height, true);
    M5.Display.endWrite();

    lv_disp_flush_ready(disp);
}

void setup() {
    auto cfg = M5.config();
    M5Dial.begin(cfg, true, false);
    Serial.begin(115200);

    // LVGL initialization
    lv_init();
    lv_disp_draw_buf_init(&drawBuffer, buffer, NULL, SCREEN_WIDTH * SCREEN_HEIGHT / 10);

    static lv_disp_drv_t disp_drv;
    lv_disp_drv_init(&disp_drv);
    disp_drv.hor_res = SCREEN_WIDTH;
    disp_drv.ver_res = SCREEN_HEIGHT;
    disp_drv.flush_cb = my_disp_flush;
    disp_drv.draw_buf = &drawBuffer;
    lv_disp_drv_register(&disp_drv);

    static lv_indev_drv_t encoder_drv;
    lv_indev_drv_init(&encoder_drv);
    encoder_drv.type = LV_INDEV_TYPE_ENCODER;
    encoder_drv.read_cb = encoder_read;
    encoder_indev = lv_indev_drv_register(&encoder_drv);

    // Create a group and assign it to the encoder input device
    group = lv_group_create();
    lv_indev_set_group(encoder_indev, group);

    // Create focusable widgets
    lv_obj_t *btn1 = lv_btn_create(lv_scr_act());
    lv_obj_align(btn1, LV_ALIGN_CENTER, -60, 0);
    lv_obj_t *label1 = lv_label_create(btn1);
    lv_label_set_text(label1, "Button 1");

    lv_obj_t *btn2 = lv_btn_create(lv_scr_act());
    lv_obj_align(btn2, LV_ALIGN_CENTER, 60, 0);
    lv_obj_t *label2 = lv_label_create(btn2);
    lv_label_set_text(label2, "Button 2");

    lv_obj_t *btn3 = lv_btn_create(lv_scr_act());
    lv_obj_align(btn3, LV_ALIGN_CENTER, 0, 50);
    lv_obj_t *label3 = lv_label_create(btn3);
    lv_label_set_text(label3, "Button 3");

    // Add widgets to the group
    lv_group_add_obj(group, btn1);
    lv_group_add_obj(group, btn2);
    lv_group_add_obj(group, btn3);
}

M5DialLVGLTouchDemo.ino

but i dont understand how to implement M5Dial.Touch.getDetail(); to get the touch

also if you have the file of user_setup.h for GC9A01. kindly share
Thank You

re TFT_eSPI : try adding the following define in Setup200_GC9A01.h

#define TFT_BACKLIGHT_ON HIGH

re GC9A01_demo : please find an M5Dial version here.

Thanks
Felix

Thank you.

  label0.setCursor(x=50, y=100)

My goal is to have LVGL running on the M5Dial so I am working my way through the display issues at this time.

GC9A01 driver

Hmm, no I did not. Let me do some research and try to find the driver
