Help in reading servo info from my R/C receiver

Archiver

I need help in reading servo info from my R/C receiver.
I have a BS2/SX
I want to read the position info that my remote is sending so I can
have the stamp make decisions as to where to move multiple servos.
I have Futaba 2 channel receiver. A Basic Stamp 2/SX. and Mini SSC II
Serial Servo Controller.

Has anyone done anything like this?




Thanks

Hello David,
to read data in from an RC receiver just use the Pulsin
command. Connect the pulsin pin to the logic signal coming from which ever
channel you are using. The receiver spits out a 50 hz pulse train
continuously. The position data (position of the stick on the transmitter)
is contained in the <width> of these pulses. The neutral position (stick
centered) is somewhere around a pulswidth value of ~1.5ms. As you move the
stick one way, the pulses will get wider until they get to ~2ms (value
returned from Pulsin increases). As you move the stick the other way the
pulses will get narrower until they are ~1ms (value returned from Pulsin
decreases).

I don't know how you want the servos connected to your SSC to respond,
but the <three byte> control format is well covered in the SSC manual. Just
use the Serout command to send the bytes to the SSC.

David,
I've never done what you are suggesting, but these guys might have an idea
how to help you: http://www.rc-soar.com/tech/dwaerialphoto.htm
They've hooked up a digital camera and BS2 and R/C receiver together to
make a remote control camera interface. They should be able to help you on
interpreting the output from your receiver.

Hope this helps,
Mike

Hi David,

See my web page at http://members.tripod.com/~divelec/r3rcjs01.html .
This is a program I've been using for about a year. It works fine.
You can download it and adapt to your needs.
