jasu Yeah, the way the example files are set up in the github repository assumes that you computer has certain libraries installed. I made a pull request against the AmbaSat-1 repository that fixes this by configuring each project to explicitly pull in the needed libraries rather than assume they are installed on the computer. See my pull request here:
The AmbaSat-1 team has not accepted my pull request yet. However, if you check it out that should fix the problem you are having.
Note that the LED project actually doesn't require any specific library to work. When you say "it doesn't work" do you mean it doesn't compile or that the LED doesn't blink once you upload the code to the ambasat?
