Expected result

This test will blink all available on-board LEDs, one after each other in an endless loop. Each LED will light up once long, and twice short, where the long interval is roughly 4 times as long as the short interval. The length of the interval is not specified and differs for each platform.

Afterwards the test will connect each on-board button to an LED (if available), so that that LED state mirrors the button state.

Background

Running this test shows if all the direct access macros for all on-board LEDs are working correctly (xx_ON, xx_OFF, xx_TOGGLE). This test is intentionally not using any timers, so it can also be used early on in the porting process, where timers might not yet be available.
