Re: RC servo to PIC controlled via RC transmitter
I am not an R/C guy, BUT I did play with servos with success. You have 3 wires on the servo. one + one - and one for signal. Signal is the key word. on tha SIGNAL wire send a pulse train of varying pulse width. The servo will change it's position. Go back to the link Acetronics2 posted, it explains it.
As for limiting the servo to 20 degrees, personally I would gear it down and use the extra resolution to make a smoother movement. You could create a lookdown table for servo positions if you need exact places for it to stop. Then you could just send your PIC a number or other symbol as instructions as where to go.
Read Sec 5.66 of the manual PULSOUT
