Expected result
|
||||
===============
|
||||
The 'red' and the 'green' LEDs of the board should light up alternating with a
|
||||
500ms interval. If your board has only one LED (probably defined as LED_RED),
|
||||
you will see only this LED blink at 1Hz. If your board has no on-board LED, you
|
||||
will see nothing.
|
||||
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.
|
||||
|
||||
Background
|
||||
==========
|
||||
All boards in RIOT define at least two macros for accessing two selected
|
||||
on-board LEDs directly. These are called LED_RED and LED_GREEN, independent if
|
||||
the actual color of those LED is red or green.
|
||||
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.
