The idle thread will call this member function once the component has been added to the array of idle components using fiber_add_idle_component.

Updates are determined by the isIdleCallbackNeeded() member function.

Reimplemented in MicroBitBLEManager, MicroBitEventService, MicroBitIOPinService, MicroBitAccelerometer, MicroBitCompass, and MicroBitThermometer.

Definition at line 127 of file MicroBitComponent.h.

When added to the idleThreadComponents array, this function will be called to determine if and when data is ready.

Note:

override this if you want to request to be scheduled as soon as possible.

Reimplemented in MicroBitAccelerometer, MicroBitCompass, and MicroBitThermometer.

Tests if this MicroBitMultiButton instance is virtually pressed.

Returns:

1 if both physical buttons are pressed simultaneously.

 if(buttonAB.isPressed())
     display.scroll("Pressed!");

Changes the event configuration of this button to the given MicroBitButtonEventConfiguration.

All subsequent events generated by this button will then be informed by this configuraiton.

Parameters:

config

The new configuration for this button. Legal values are MICROBIT_BUTTON_ALL_EVENTS or MICROBIT_BUTTON_SIMPLE_EVENTS.

 // Configure a button to generate all possible events.
 buttonAB.setEventConfiguration(MICROBIT_BUTTON_ALL_EVENTS);

 // Configure a button to suppress MICROBIT_BUTTON_EVT_CLICK and MICROBIT_BUTTON_EVT_LONG_CLICK events.
 buttonAB.setEventConfiguration(MICROBIT_BUTTON_SIMPLE_EVENTS);

The system timer will call this member function once the component has been added to the array of system components using system_timer_add_component.

This callback will be in interrupt context.

Reimplemented in MicroBitSystemTimerCallback, MicroBitButton, and MicroBitDisplay.
