@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

Hi, So i have a ISO RS485 and i need to get modbus working on it. The primary problem im facing is that the module is UART based and by my understanding M5Dial has I2C and GPIO ports. Is it as simple as hardware serial and setting 1 and 2 pins to UART or is there something else to it
Also it would be great help if there are any modbus library that can be used.
Thank You

Hi, I have been experimenting on m5dial recently and i have been having difficulties with putting images on display . How do i store images on flash memory in platformIO or do i just need header files with image arrays? Thank You

@navatek Hi, thanks a lot for the solution. finally it works and displays images normally
i was wondering if you have tried doing the same on arduino or other platforms.

@ajb2k3 i did, but it just doesn't show the image . I tried inserting the byte array to an other online complier and it gave the output as required
can you please tell me what you use for images as UIflow 2.0 doesn't work for me as well
thank you

@mukul_100_ Has anyone got this working on a M5Dial? if they have i can check what actually is going wrong

Cannot upload any images to my M5dial , not through UIflow 2.0 or arduino
i tried one example of M5gfx called drawImageData which is giving output image as per the btye array but when i put values i got from converting an image to c i cannot display anything
Thanks for the help

@ajb2k3 hi thank you for the response
i did try the suggested jpeg format with a 19kb file and it still shows no image but the default image label shows when no file is given to it
can it be the image itself or uiflow 2?

Hi, even i am facing the same issue with uiflow 2, the image is in jpg and 100x100px
please help.
Thanks
