Implementation Method: In this example, the LVGL image refresh completion is notified within the DMA transfer completion interrupt service function. Using a blocking notification mechanism would prevent leveraging the double buffering mechanism to enhance the refresh speed. static void dma_handler(void) {...
Functionality: It's necessary to notify the LVGL core after each image refresh is completed so that LVGL can prepare for rendering the next refresh image. Implementation Method: In this example, the LVGL image refresh completion is notified within the DMA transfer completion interrupt service functio...

Function: Creating controls requires using different function interfaces for different controls. It's possible to choose a parent object for creation. lv_obj_t *btn = lv_btn_create(lv_scr_act()); //Create a control where the lv_scr_act layer is the parent of the button, which can be ...
