Output without modulation #11

Reported by bluey on 25 Jul 2012 14:04 UTC Sometimes you want to output the IR signal with no carrier -- ie the input expecting a demodulated signal as is sometimes found on the IR in port of receivers, etc.

So, feature request: when carrier frequency set to 0, do not do any modulation. This way you can plug dual socket directly into those kinds of stereos to control them.

Commented by jdunn on 29 Jul 2012 23:31 UTC Interesting idea and should be quite simple to implement in the firmware. I would suggest that we use a different flag than 0 though simply because 0 currently means "use default", i.e. 38kHz. We can pick some other flag value like 0xFFFF for the two fields that control the frequency. Internally we will still be looping at 38kHz, but without changing the pin state.
