embeddedartists | 1:46c8df4608c8 | 21 | * Base class for all Apps. The idea is that you can have multiple |
embeddedartists | 1:46c8df4608c8 | 22 | * Apps in your program. Each App has three funtions: |
embeddedartists | 0:4977187e90c7 | 23 | * |
embeddedartists | 1:46c8df4608c8 | 24 | * setup() is called to let the App load all needed resources |
embeddedartists | 0:4977187e90c7 | 25 | * |
embeddedartists | 1:46c8df4608c8 | 26 | * runToCompletion() is called and will not return until the App exits |
embeddedartists | 0:4977187e90c7 | 27 | * |
embeddedartists | 1:46c8df4608c8 | 28 | * teardown() is called to let the App free allocated resources |
embeddedartists | 0:4977187e90c7 | 29 | * |
embeddedartists | 1:46c8df4608c8 | 30 | * For an example of Apps in use, see the AppLauncher class |
