I was wondering how you set up unzap to learn codes. According to the project page it contains a "learning mechanism (which
can detect the correct carrier frequency)" but I couldn't find anything that learns codes in unzap.c. I would have thought that finding the carrier frequency would require sampling from the ADC and then running some sort of FFT to find the frequency, but the receiver is not connected to an ADC port. Can someone help me understand this?<br>
