Summary
Chapter 7 introduced you to some pretty complex subjects, including the use of external ICs. You are not even half way through the projects yet and you already know how to control a dot matrix display using both shift registers and a dedicated LED driver IC. Also, you learned how to coding things the hard way and then how to code the easy way by incorporating a ready-made library designed for your LED Driver IC.
You have also learned the sometimes-baffling concept of multiplexing, a skill that will come in very handy for many other things as well as dot matrix displays.
Subjects and concepts covered in Chapter 7:
- How a dot matrix display is wired up
- How to install an external library
- The concept of multiplexing (or muxing)
- How to use ...
