|
|
* Driver for the Zoul user button
|
|
*
|
|
* The user button (on Zoul-based platforms like the RE-Mote and the Firefly)
|
|
* will generate a sensors_changed event on press as well as on release.
|
|
*
|
|
* Unlike many other platforms, the user button has the ability to
|
|
* generate events when the user keeps the button pressed. The user can
|
|
* configure the button driver with a timer interval in clock ticks. When the
|
|
* button is kept pressed, the driver will then generate a broadcast event
|
|
* each time the interval passes. For example the driver can be configured to
|
|
* generate an event every second while the button is kept pressed. This
|
|
* functionality can be enabled through the configure() function, by passing
|
|
* BUTTON_SENSOR_CONFIG_TYPE_INTERVAL as the type argument.
