Monkey

A simple monkey test. Use random input to stress test the application.

Usage

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.
