I just basically finished up a final project for an embedded systems class, but I want to add remote control capabilities. I need 14 buttons for 14 different commands for the hc11. I have never done this before and am a little lost.
I have an IR receiver that operates at 38kHz, which is currently connected to PA2 of the microcontroller (generic input capture port) through a simple amplification circuit. I have spent many hours with it (pretty sure I have correct code and setup), but nothing works. I have tried many of my remotes, but I don't know what their carrier frequencies are so I can't tell if they even should work.
Does anyone know of any remote controls that operate with a carrier frequency of 38kHz?
Also, I have a HT12D decoder, but I do not know if I need to use it. Can someone tell me when the decoder should be used and when it doesn't need to be used?
I'm open to any suggestions too.
thx
