Pulsin from r/c receiver
Archiver
Posts: 46,084
Hi,
I'm having trouble centering my servos, so what I want to do is get
the pulse from my r/c receiver, get my bs2p to read it, make
the "center" value +/- 10ms, and send the same pulse to 4 modified
servos.
Currently, I have 2 control wires from my Hitec receiver from ch. 1
(plugged into P1) and ch. 2 (plugged into P2). 2 servos are
connected to P14 (ch. 1) and the other 2 servos are connected to P15
(ch. 2). I can pulsout the servos, but I'm having trouble with
pulsin.
If anyone knows how to get the pulse from an r/c receiver, please
let me know. The center value for my bs2p is 1795 ms.
Thanks,
Harrison

I'm doing a similar thing with a Robbe Futaba receiver.
My problem was that I did'nt get response on Pulsin, the cause was that the
pulse-voltage from the Futaba was about 3 volts which is not enough for te
Stamp.
My solution is to put in a transistor which amlifies the pulse and also
inverts the signal. No problem, the Stamp can handle a negative Pulsin.
It works fine here, I hope you will find a solution to your problem to.
Regards,
Klaus

display it on a serial LCD -- check it out and adapt it for your BS2p
(which has better PULSIN and PULSOUT resolution).
