A revisit of this commnd.
 

In the code below, what I am expecting is, goes to pulsin command sub, times out, turns the LED on and off, and keeps repeating. Now, what is ocurring is that the LED does not turn on, means it never got out of the pulsin sub? I tried it with temp1 = 0, that did not do anything for me. So, I tried pushing a button on the remote, and the LED did turn on. My question is, when the program gets to a pulsin, does the program just hang there until it times itself out, or does it just wait until something occurs on the pin (IR demodulator in this case). I thought I read that their is supposed to be a 50 ms time out. In my program did I insert something weird.

 

I just tried it in a stand-alone, and the program works as expected. As soon as I give it power the LED starts to go on and off. Something weird is going on, in stand-alone it works as expected, with SX-key it just hangs there (I hope I did not mess up my board).

 

Any comments will be appreciated.

 

Thanks
