Enable LV_USE_MONKEY in lv_conf.h. First configure monkey, use lv_monkey_config_t to define the configuration structure, set the type (check input devices for the supported types), and then set the range of period_range and input_range, the monkey will output random operations at random times within this range. Call lv_monkey_create to create monkey. Finally call lv_monkey_set_enable(monkey, true) to enable monkey. If you want to pause the monkey, call lv_monkey_set_enable(monkey, false). To delete the monkey, call lv_monkey_del(monkey). Note that input_range has different meanings in different type: LV_INDEV_TYPE_POINTER No effect, click randomly within the pixels of the screen resolution. LV_INDEV_TYPE_ENCODER The minimum and maximum values ​​of enc_diff. LV_INDEV_TYPE_BUTTON The minimum and maximum values ​​of btn_id. Use lv_monkey_get_indev() to get the input device, and use lv_indev_set_button_points() to map the key ID to the coordinates. LV_INDEV_TYPE_KEYPAD No effect, Send random Keys.
