how to blink an LED

In case you don't already know why blinking an LED is one of the first things you probably want to do when bringing up some new hardware, see "why blink an LED?"

There are lots of ways to blink LEDs ranging from learn-the-hard-way to trivially-easy to massive-overkill. Here are a few ways relevant to this project.

If blinking an LED is all you want to do, then just let the RTOS do all the work for you:

examples/blinky built into RIOT OS

But of course you're going to want to do a lot more than just blink an LED, so use the fargin framework:

blinky.minimal partial (minimal) framework

blinky.serial-service access native code services from a PC for development/test

blinky.full-framework full fargin firmware framework
