I'm not sure if its "RC5" or not. I don't suppose it really matters as far as the Ir demodulator is concerned. I do know there are 13 bits total. Its going to matter only from the standpoint of the remote control I use, correct?

Also, this would have to be interupt driven. Basically what I am doing is adding an IR remote system to an existing robot idea I am working on. Regardless of the autonomous behavior of the robot, I would want it to instantly do whatever instruction it recieved from the controller. Are there some good sites that show examples on how to implement interupts? (I'm a little confused on the organization of where the interupt routine fits into eeprom)
