Monkey

Generate random input events to stress-test the UI and surface hard-to-reproduce bugs.

Pointer monkey input

Generate random pointer events with LV_INDEV_TYPE_POINTER.

lv_monkey_config_init initializes a config which is then set to LV_INDEV_TYPE_POINTER with a period between 10 ms and 100 ms. lv_monkey_create registers the synthetic input device and lv_monkey_set_enable(monkey, true) starts the stream of random clicks.

Encoder monkey input

Feed random encoder steps into a new default group for focus testing.

The config is set to LV_INDEV_TYPE_ENCODER with a 50 to 500 ms period and input range of -5 to 5. A fresh lv_group_t is created, bound to the monkey's indev with lv_indev_set_group, and installed as the default group. lv_monkey_set_enable then starts the random encoder events.

Button monkey input

Fire random button presses mapped to three fixed screen coordinates.

The config is set to LV_INDEV_TYPE_BUTTON with a 50 to 500 ms period and an input range covering indices 0 through 2. Three points are placed along the top of the screen at hor_res/4, hor_res/2, and hor_res*3/4, then bound to the monkey's indev with lv_indev_set_button_points. lv_monkey_set_enable starts the random presses.
