hi guys/gals i am looking for fm transmitter and reciever code for radio controlled models, been looking for it all over the net with no luck maybe some here has any of that kind. best is any exampels for keil .
many thanx in advance /sphinx
I'm not quite sure I understand your question.
Do you want to know how to control a servo motor, or do you need to transmit to a receiver that will control the servo motors?
If all you need to do is control the servos, that is fairly easy. Take a look with a scope at the lines going into the servo when they are working. You'll find power, ground, and a pwm control line. replicate the pwm and you've got control of the servo.
If you need to transmit to a receiver, you've got a lot more hardware work to do, unless you can find a way to jack into the existing transmitter. I've got a few ideas for how to do that, but I don't know your goals, so it's hard to say what the best option would be.

If you need to transmit to a receiver, you've got a lot more hardware work to do many RS-xxx to RF transciever boards are available at a quite reasonable price. Designing a RF transciever ( i.e. "you've got a lot more hardware work to do") is not kid's play.
