C.4.3
The flowchart for this demo is shown in Figure C-6, however, the flowchart does not
show the debounce routine implemented in ButtonPress(). The debounce routine
is based on the Brute Force Debounce (described in Lesson 1, Section C.3) with one
slight modification, the debounce routine is implemented as a state machine. The
Debounce state machine differs from the LED state machine where the states them-
selves modify the state variable. Implementing the debounce routine as a state
machine is easier to understand than implementing it as looping code.
C.4.3.1
As mentioned earlier in Section C.4.1.2, state machines are useful in nearly every
application. The LED library, in subsequent lessons, utilizes state machines to light the
LED similarly to the state machine implemented in this lesson. State machines are use-
ful for bit banging any number of communication protocols, receiving RF transmissions,
controlling the speed of a motor – the list goes on and on. Understanding the states
necessary to make the application work is a good way to begin implementing an appli-
cation.
