@gordsh in your code, is the press function working successfully?
i am getting crashes for now, i am trying to use the button as a external button and not as a encoder button, the main problems seems to be init of button

@gordsh Oh great thanks a lot, I actually got it working,
and after seeing your code i tried to implement the button part with encoder but the dial seems to crash repeatedly because of it. For now that is not my focus so i will try it again later.
Also , do you have any idea how the implementation of encoder is eez studio is.
i understood that the group is to be made but didnt quite understand how to append/impelment the encoder events to it
If anyone has any idea or reference, Thank you in advance.

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);
}

@mukul_100_ Got this workking by using m5unified instead of tft_espi
But i can get the touch to work
as per what i read lvgl uses polling to get the touch coordinates using lv_timer_handler();

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

@gordsh Hi ,
did you get this working ?
I am banging my head against the wall with this one right now ,
I am trying to use EEZ Studio with M5dial and using platform.io (or arduino ide whichever works)

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

Hi everyone, Im currently working on a UI for M5Dial and got this idea from the image attached for making four quadrants or arcs and then adding functionality.
i have got the functionality right but i dont understand how to get the fading effect or gradient effect on the arcs.

im using platformIO right now
If anyone has inputs, kindly reply, Thanks.

@felmue Hi, felix i got it working finally. The issue is, on platformIO the library Arduinomodbus library and ArduinoRS485 library are the arduino ones and not the m5stack ones which is why i was getting error.
A fix to this was to just replace the internal files of library to the m5stack ones from github.
Thank you for the help.

@felmue ,did you make any changes in the RS485.h file
along these line 46
#else
#ifndef RS485_DEFAULT_DE_PIN
#define RS485_DEFAULT_DE_PIN A6
#define RS485_DEFAULT_RE_PIN A5
#endif

thanks,
Mukul

@felmue Hi felix
the changes you mentioned are in the same example code that is linked above?

@felmue hi felix sorry for the late reply, finally got a chance to get back to this

i studied the example but not sure if i understood how to implement the master slave concept through this and also there is a error thrown in
RS485Class RS485(Serial2, GPIO_NUM_1, GPIO_NUM_2, -1, -1);

as there are only 4 arguments accepted by the class
also serial2 needs some tweaking for esp32 right?
thanks

i am using platformio right now. thanks
