创建3个LED示例

static void lv_example_led_1(void)
{
    
    /*Create a LED and switch it OFF*/
    lv_obj_t* led1 = lv_led_create(lv_scr_act());  //创建LED对象
    lv_obj_align(led1, LV_ALIGN_CENTER, -80, 0); //LV_ALIGN_CENTER方式对齐-80，0
    lv_led_off(led1);  // LED OFF
    /*Copy the previous LED and set a brightness*/
    lv_obj_t* led2 = lv_led_create(lv_scr_act()); //创建LED对象
    lv_obj_align(led2, LV_ALIGN_CENTER, 0, 0); //LV_ALIGN_CENTER方式对齐0，0
    lv_led_set_brightness(led2, 150);  //设置LED亮度
    lv_led_set_color(led2, lv_palette_main(LV_PALETTE_RED));  // 红色
    /*Copy the previous LED and switch it ON*/
    lv_obj_t* led3 = lv_led_create(lv_scr_act()); //创建LED对象
    lv_obj_align(led3, LV_ALIGN_CENTER, 80, 0); //LV_ALIGN_CENTER方式对齐80，0
    lv_led_on(led3);   // LED ON
}
