I have another question though and that is that the IR demod chip that I have (the 3 legged jobber) gives a 4.8mS (200Hz)square wave even when it is not receiving anything, the Level 1 is for about 3.6ms and the Logic 0 is about 1.2mSecs.
Is this normal?

Marshall,

It may be the environment noise.
Is it happened if you close the receiver?

Simon,

What are you asking about? Do you want to find another decoder routine? Or what?
