ACTIVITY #2: DESIGNING A REUSABLE REMOTE PROGRAM
Up to this point, you have completed a program that performs IR remote message capture
and decoding for SONY TV signals. Before doing more Boe-Bot applications, it's better
to rewrite the program so that all the work is done in subroutines. Along with the
subroutines, the program should also have
declarations for the variables that are used by the subroutines.
Building an Application for Reading the IR Remote
This next program is a more reusable version of PulsesToByteValueYourTurn.bs2. Here
are the changes that were made to it:
•
•
•
•
Constants – keypad values with meaningful names
Variables – variables that have to be used with the subroutines
Main routine – call the subroutine and display the data
Subroutine – capture message pulses from the infrared remote and decode
Table 2-1 was used to build a list of
The
section.
A very simple main routine that displays the IR remote code in the Debug
Terminal was inserted here along with a comment to add your own code.
This one should contain everything inside the main the
PulsesToByteValueYourTurn.bs2.

declarations from PulsesToByteValue.bs2 were given their own
