how to interface an 8051 to an RF transmitter ?

I need to transmit a string of message between two Radio frequency transmitter. The message will be stored a microcontroller (e.g. 8051). How to go about writing a program for it and how to interface between the micrcontroller and the transmitters. I am still an amauteur when comes to embeded programming. Any source code or info on this ?

  • Hi,
    What you need to do is decide on a protocol...may be you have to use 2 pairs of trans. and recev.

    When ever a receiver receives a command it has to send back some other character...if this character is recevied by the other trans. it means that the unit is within a specified range.

    For this you can make use of the USART.

    The above modules support RS-232.

    Any thing else...
