CHAPTER 2 ■ SERIAL COMMUNICATION 41
Figure 2-6. The Parallax BASIC Stamp
Figure 2-7. The Parallax Javelin Stamp
When using either Stamp with your Java programs, I have found it tedious to perform the
same serial port and byte management for each class that will access the Stamp. To resolve this
problem, I’ll create a class that handles all communication with the controller. But like the serial
port, I may have different implementations for access, so first I want to create an interface for
all controllers, and then I want to write an implementation class specifically for my Stamp.
