FreeRTOS port compile errors.

Here you go!

I added a example program to the library, you should be able to open that program and flash it right to your board without any problems. It should be a good project to branch off of and make things work.

When I have free time, I will try to add more examples and update the readme more.

Let me know how it works, would love to hear what you end up making with it :slight_smile:
