A blog of a thousand posts begins with the first post.

A learner of a new programming language usually starts with ‘Hello World’ which prints the text “hello, world!” to the console. This is not so stupid as it sounds, because it is a first test if your environment works as expected.

Similarly a learner in the embedded world starts with “Blinky”, a program that blinks a LED on your development board. This program is typically provided by the manufacturer of the board or toolkit that you are going to use. It gives a first impression how a program looks like. Furthermore, if you can compile the program and upload it to your board you know that you are up and running with the toolchain.

For that reason I will do that as well.
