LED blinker is certainly the equivalent of "Hello World" in the embedded world. This tutorial explains how to blink a LED using REOBoard. We assume that you are already familiar with integrated development environments such and Eclipse or equivalent. We also assume that you have a minimal knowledge about C/C++ programming language.
In the first tutorial, we have explained how to blink a LED at a fixed interval. But the biggest problem of this first program was that the processor was working full time to do almost nothing (i.e. waiting). In this tutorial, we explain how to take advantage of timers to do the same function.
