// This version of the Dimmable LED Service is similar to the one last used in Example 11, but now includes support for 3 physical PushButtons
|
||||
// performing the following actions:
|
||||
//
|
||||
// power button: SHORT press toggles power on/off; LONG press saves current brightness as favorite level; DOUBLE press sets brightness to favorite level
|
||||
// raise button: SHORT press increases brightness by 1%; LONG press increases brightness by 10%; DOUBLE press increases brightness to maximum
|
||||
// lower button: SHORT press decreases brightness by 1%; LONG press decreases brightness by 10%; DOUBLE press decreases brightness to minimum
|

|
||||

// its default values for a LONG press (2000 ms), a SINGLE press (5 ms), and a DOUBLE press (200 ms). In the second and third we change the
|

// default LONG press time to 500 ms, which works well for repeatedly increasing or decreasing the brightness. Since we do not specify
|
||||
// a triggerType, SpanButton uses the default TRIGGER_ON_TOUCH, which is suitable for a pushbutton that connects pin to GROUND when pressed.

|
||||
|
||||
// Note the line below is similar to, but not the same as, the ledPin->set function used in the update() method above. Within the
|
||||
// update() method we used getNewVal() because we wanted to change the LED to match the NEW VALUES requested by the user via the
|
||||
// HomeKit Controller. We did not need to (and must not) use setVal() to modify these values in the update() method since HomeSpan
|
||||
// automatically does this for us, provided we return StatusCode::OK at the end of the update() method.
|
||||
|
||||
// But in the button() method, getNewVal() means nothing, since the button() method is not called by HomeKit in response to a user request
|
||||
// from a HomeKit Controller interface. Instead, we are manually changing the values of one or more Characteristic using setVal() in response
|
||||
// to SINGLE, DOUBLE, and LONG SpanButton requests. These changes are instantaneous, so we can retreive the new values with a subsequent call to getVal(),
|
||||
// as shown below. As usual, HomeSpan will send Event Notifications to all registered HomeKit Controllers letting them know about any changes
|
||||
// we made using setVal().
|
||||
|
||||
ledPin->set(power->getVal()*level->getVal()); // update the physical LED to reflect the new values
|
||||
