Here is a simple example of how to do 'different things' when you press
various
buttons on your remote. If you press digits, they are displayed on the
LCD.
If you press rewind, the LCD is cleared. When you press stop, the
program
ends. If you press anything else, Huh? is displayed on the LCD.
Remember that all of the button and setup values used are for my RCA
remote.
First use the test.c program to determine all of the correct values for
whatever remote you have and insert them where indicated.

| How would I use an if/then statement if I used the onboard IR reciever? Earlier, I downloaded a program that Max Davies wrote to determine the different variables for my remote. In the readme file, it says that the rules are set by a command like (...) (27 years ago, 10-Apr-97, to lugnet.robotics.handyboard)
