Example 2-1 shows a typical main() calling the various functions that make up the
software control loop.
EXAMPLE 2-1:
An infinity loop will be used by all labs in this user’s guide created using a while
loop that repeatedly call the functions within the curly braces as long as there is power
to the microcontroller.
Global variables are used wherever needed in lieu of passing variables between
functions.
