Im new to the whole RF area and I have no idea as where to start.
My ultimate goal is to use an infared remote control, remove the led and install a optocoupler in its place. Then use that as a serial input into the RF IC. At the receiver end I would change back to IR.
Im looking for some guidance, ive been looking at the TI cc1150. Im not sure if this is exactly what im needing though. Heres the data sheet.
Actually that is a pretty good question. The output of the receiver HAS TO BE exactly the input to the transmitter. You want to make sure that the transmitter does not corrupt the digital data any way, such as adding a header, or changing any ones into zeros for Manchester coding, etc.
The RFM is a good one. A lot of transmitters for such things run at 312 or 430 Mhz range. They are typically crystal or Saw resonator oscillators that are simply turned on/off.
Cool, im gonna order the RFM. Now I can use the same one for receiver/transmitter right? Im pretty sure its a transceiver.
You know whats funny, is that if it in fact did change the the signal it would be ok. Weird, yes, but il explain why. Its gonna be used for a Leviton lighting control system, the cool thing about the controller is that it can learn any IR signal, as long as its in the 38kHz range. Its pretty neat.
