Feature proposal: RTL-IR make a plugin to use the IR receiver present on some rtl-sdr dongles

Open Nesos-ita opened this issue 6 years ago • 1 comments

I have an rtl-sdr that has also the ir receiver and i managed to get it working for ANY ir signal (not only the included remote+included program), i made a C program that receive data on windows.
i can dump raw signal at a fixed sample rate (no problem) and fixed max length (this might be a problem, needs to be studied)
For example any tv ir is no problem, but air conditioner ir sends the whole state for each keypress and it is too long.
Data it's encoded as bytes where MSB bit is 1/0 according to the value, the remaining 7 are the length of the 1/0 (for how long in time it stay at 1 or 0)
I don't know how to make plugins for this program but maybe it's useful for someone (me included)
I saw that you recently added soundcard support which is awesome and maybe my idea is not that useful as you can insert an ir led in the mic input on soundcard and use that one (avoiding fixed max length problem)
but maybe it's useful as rtl-sdr receiver is a real receiver... using only an ir led in the mic allows you only few cm of range and needs some components (jack +led+ soldering)
any thought??

Actually we already discussed IR support some years ago but didn't implement it due to lack of time. Maybe we will bring the discussion back to live but probably not with highest priority.
