# 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](/overview/indev) 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](/overview/indev).
