Most microcontroller boards start with example code that blinks a LED. Galago has a LED just below the main CPU which we blink with this example. In contrast to simpler platforms, Galago is designed for asynchronous, task-driven operation. For this reason, we blink the LED with two tiny 'jobs' that occur on a fixed schedule. The CPU sleeps the rest of the time, saving energy and freeing it up for other potential tasks.
