14. Interface and Application Programming

Task of Interface and Application Programming

Group assignment:

• Compare as many tool options as possible.
• Document your work on the group work page and reflect on your individual page what you learned.

Individual assignment

• Write an application for the embedded board that you made. that interfaces a user with an input and/or output device(s)
