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 ?
can you send me a sample projects...a simple projects not that is not so expensive and easy as well..
our teacher told us to search for a simple project that 8051 could be apply..just a simple projects that is not costly...affordable for the students can you give and example of this project?can you send me?
"can u help me to select..." Nobody can help you select anything when you've given no criteria at all on which to base the selection! Besides, this is a forum for discussing Keil software tools - not hardware selection!
"and to interface to microcontroller(PIC)." You'll need to find a PIC forum for that!
can u help me to select a RF module for data communication between devices and to interface to microcontroller(PIC).
please send circuit to my email khalili_m1@yahoo.com

Hi Manoj Do you have any circuit idea for transmitter/receiver module. Or any module available in India for hobby projets. Thanks
hi,,, i need how to interface the 8051 at an RF tarnsmitter,,, please send code
Better go to a PIC forum, then!
Christo, I am currently trying to send data from the pc by the serial port to a rf transiver and then received by another rf transiver to be accepted by a PIC. Any simple source code to help me out. I am stuck on how to get the PIC to accept the RF signals and decode them to proper PIC signals.

What i wan to get is the circuit.. I can't seem to find any circuit.. Any site to recommend
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... Rgds Raj Shetgar
Actually i got a circuit which use Ultrasonic transducer. But it can only detect when the transducers is in line of sight... so i decided to use RF.
