Hi, I need to transmit a simple 0 or 1 over a very short distance, however I cannot use a wire, so I have to find an RF solution.
I figure PPM is the best solution, the transmitter at least is very easy to create. Since I shouldn't send a simple continious 1 when on and 0 when off I figured a simple 010101 would be enough. I can make a MCU recognize the pattern and timing, the only problem I have so far is turning the alternating RF signal into a 1 and 0.
Basicaly what I'm trying to achieve is very similiar to how the RX2B/TX2B ICs work, I just don't need all the different commands that it can send. I currently have a system using those ICs and it works, but I thought I'd try to figure out a little less wasteful version of it.
So, if anyone knows how the RX2B manages to "clean up" the recieved signal, that would be great.
