It is necessary to rotate the scale, I thought of using a meter ui_hdg_scale = lv_meter_create(approach_screen); lv_obj_set_pos(ui_hdg_scale, -158, 29); lv_obj_set_size(ui_hdg_scale, 800, 800); lv_obj_set_style_radius(ui_hdg_scale, 0, LV_PART_MAIN | LV_STATE_DEFAULT); lv_obj_set_style_te…

can you test this code?it work well in my vs2019 simulator static void scale_cb(void* var, int32_t v) { lv_scale_set_rotation(var, v); } void lv_example_scale_8(void) { lv_obj_t* scale_loader = lv_scale_create(lv_screen_active()); lv_obj_set_size(scale_loader, 300, 300); lv_scale_set_mode(s…

How do you try to rotate it? If it’s an option I suggest updating to v9 as lv_scale (replacement of meter) is much more powerful.

I really appreciate your help, and forgive me if I ask stupid questions🙂 [image] kisvegabor: How do you try to rotate it? First I draw the scale and then I try to rotate it using the parameter rotation void lv_meter_set_scale_range(lv_obj_t * obj, lv_meter_scale_t * scale, int32_t min, int3…

Hello @kisvegabor I need your help into :roll_eyes: [image] Lv_scale animations with C++ class How-to Hello @TridentTD and @ZooM Thank you for the relevant question and answer🙂 I’m also looking into creating a class and animating or moving the meter scale elements. As …

There is a zero division error in lv_scale · Issue #7591 · lvgl/lvgl

Thank you for your participation🙂 I wrote a c++ class based on your code, but unfortunately I don’t get the scale rotation in the simulator. class ColorScale { public: ColorScale(lv_obj_t* parent, int pos_x, int pos_y, int size_x, int size_y); static void draw_event_cb(lv_event_t* e); …

[image] lizhaoming634: can you test this code? Yes, I’ll try your code now, but I also got something :grinning: class Hdg_rotate { public: Hdg_rotate(lv_obj_t* parent, int x, int y, int width, int height); void start_color_animation(); void set_rotation(int angle); // Method for …

Hello @kisvegabor Please add to the examples with the scale Scale (lv_scale) - LVGL 9.3 documentation Widget for rotating the external scale. Thank you :grinning:

Nice! Thank you! @fbiego if you have a little bit of free time, can you add an example based on this ?

@fbiego I corrected the code a little, please add it :grinning: static void scale_cb(void* var, int32_t v) { lv_scale_set_rotation((lv_obj_t *)var, v); } void lv_example_scale_12(void) { lv_obj_t* scale_loader = lv_scale_create(lv_screen_active()); lv_obj_set_size(scale_loader, 300, 300); lv_scale…
