| # Component: Keyboard Button | ||
| [Online documentation](https://docs.espressif.com/projects/esp-iot-solution/en/latest/input_device/keyboard_button.html) | ||
|
|
||
| `keyboard_button` is a library for scanning keyboard matrix, supporting the following features: | ||
|
|
||
| List of supported events: | ||
| * KBD_EVENT_PRESSED | ||
| * KBD_EVENT_COMBINATION | ||
|
|
||
| * Supports full-key anti-ghosting scanning method. | ||
| * Supports efficient key scanning with a scan rate of no less than 1K. | ||
| * Supports low-power keyboard scanning. | ||
|
|
||
| ## Add component to your project | ||
|
|
||
| Please use the component manager command `add-dependency` to add the `keyboard_button` to your project's dependency, during the `CMake` step the component will be downloaded automatically | ||
|
|
||
| ``` | ||
| idf.py add-dependency "espressif/keyboard_button=*" | ||
| ``` |
