Hello Friends ;-),
I have successfully programmed a PIC12F628 to generate a 1 ms to 2 ms RC PWM signal every 20 msecs. I'm able to change the pulse width of the PWM signal by turning a potentiometer knob.
Using radio frequency modules such as TWS-434 and RWS-434, I would like to transmit this PWM signal to the receiving end. The receiving end should be able to receive the PWM or PPM signal and pass it onto a servo motor or to a PPM decoder.
Last week I purchased a pair of TWS-434 and RWS-434 RF transmitter/receiver modules along with the remote control IC's HT12-E and HT-12D.
The trouble is, the TWS-434 and RWS-434 modules do not seem to accept an RC PWM signal directly. I guess it might be because they expect to see a manchester encoded signal with a 50% duty cycle on the data lines.
So can you suggest a means by which I can use easy to interface RF modules similar to the one mentioned above to transmit PWM/PPM signals? Thanks in advance for your responses :wink:. They are very valuable to me.
With Regards,
John Reid
