Has anyone done any Basic Stamp programming to read inputs from a RX. I'm currently doing a google search but thought I would throw out this comment and see if anyone had been down this path before I dig into it.

Some basic stamp programming to read channels from RX.. Lots of interesting reading about alot of robotics...

Anyone else??

Basic Stamp programming for RX inputs

I didn't check the links you posted, but the concept for any microcontroller is the same.

You need to figure out the pulse width of the incoming signal and convert it into the information you are looking for. Not sure if the Basic stamp will do it (most likely it will).

I got turned off on basic stamps when I spent some time with a couple of robotics guys here and decided they were idiots, then just simply extended their favorite choice of controller to the same opinion without even trying it.

I had the controller for another project that I never did finish. So I was wanting it to read the what the RX was sending out and turn on or off outputs based on the pulsewidth. After looking at the above code and getting out the 1 1/2 inch manual that came with it, I found it has a command that turns an i/o pin on for reading pulse timing.. COOL... So maybe it will not be as hard as I thought at first.

It is very easy to program, I think the command in PULSEIN or something like that.

These things are perfect for reading in RX commands and outputting to servos.

I used one several years ago to read in the airspeed and control a movable nozzle on a ducted fan, worked great.

Make sure and do a range check, sometimes different types of code will cause different emissions, be careful

Do I read between lines here as interference?

You need to make sure that the Stamp does not affect your range. My checks were fine.

But sometimes the type of code you write can effect the potential for interference, more so on the more complex hardware architectures than the Stamp.

They are awesome but it never hurts to be careful.

I am thinking of using one to control the hydraulic pump powering the landing gear and landing gear door system on a twin turbine MIG 29.

You guys are talking about something that would seem quite interesting, but I don't really know what you are all talking about.
I would love to know more from you guys and not from the web site at this time.
Sorry for my ignorance.

Have a look at the code for my Stamp-based R/C Digicam camera interface, which reads pulses from an Rx and does serial output.
