A Bit of a Bind

What are you going to use the SSC-32 to do on this helicopter? Knowing what you are trying to accomplish will allow everyone to help you better.

To use the SSC-32, you do need a microcontroller or computer, and it needs to be programmed to do whatever processing you want and the SSC-32 commands.

Well I want to use the SSC-32 to control the servos that will control pitch of the rotor blades so that i can control height pitch and roll. After I finish the comand i want the servos to reset back to the orignal position.

ok I’ll ask, why do you want to use an SSC-32 to control a helicopter? is the helicopter tethered or something?

i think it might be because he thought the SSC-32 would be able to hold the commands itself, rather need a micro to send commands to it

no… the SSC is going to be wired to a RC reciever and the transmitter will be in a base on the ground. I want to use the SSC to program the servos that will control the helicopter. The remote will control the servos i just need the SSC to reset the servos after i change the comand on the control consol…if that makes any sense

Short answer, you cannot hook up the SSC-32 to an RC receiver.

So how does one wire an ssc to an RC receiver?

Through a microcontroller, which interprets the output of the R/C receiver, translates it into serial commands for the SSC-32, and sends it via the serial link. The SSC-32, “Serial Servo controller, 32 channel”, does exactly that - it controls up to thirty-two servos, based on serial input.

If you want to do some sort of signal processing between the R/C receiver and the servos (which is what it sounds like to me), then there will have to be a micro involved somewhere in the command chain, running a program that will interpret and react to commands from the R/C receiver, change the servo responses accordingly, and pass those along to the SSC-32, which will carry out the modified commands, telling the servos where to go.

IdU this question…Unless its meant to be that way :confused:

Now that makes sense. I would deffinately go down this path snowboarder.

Sounds like an interesting gizmo. Where does one find/purchase these, as I don’t really follow the RC world?

You will have to put what you are talking about in english, as “chat speaK” usually finds its way to my “bit bucket”. :wink:

IDU = I dont understand :laughing:

So let me get this straight, in order to get the RC reciever to semi-control the servos i would hav to connect the RC reciever to the mirco and then the mirco to the SSC.
Also i’m hearing that this can’t be done, but now i’m hereing it can’t

Nate

PS: the RC Transmitter and Reciever are on a 75.590 Freguency

yes, it can be done, and yes, you have it correct, that it wat you would need to do to sontrol it via SSC-32, u could also just use the basic atom and the mini ABB, i woultn’t think u have more than 16 servos

PS. zoomkat check ur PMs, i sent you one

How would he code the ABB and BA to interpret RC PMW signals??

im not sure, but myself and nickresier talked about it once, and he said it could be done, and seamus just said it again, it recieves it, converts it, then outputs it to the SSC-32 again

yes thats what i am exactly getting.

Thanxs Everyone
NATE.

You’d find one here in the amateur robotics world, rather than off the shelf of an R/C supplier.

What you’d basically be doing is taking a microcontroller, such as an Atom or Atom Pro, and using it as a middle-man to interpret the signals from the R/C set to the servos, according to a program you supply, that achieves what it is that you’re trying to accomplish. It then provides a serial stream to the SSC-32, which handles the generation and maintenance of the signals that control the servos.

Hopefully, this will help to illustrate the point:

So it hasn’t actually been done. Not an expert, but from the “big picture” given, assumptions are being made that have yet to worked out or proven. I don’t like misleading nubies with what appears to be non proven hardware/software solutions.

ive had my r/c receiver hooked up to my BS2 ,i dont have the code (comp crashed ) but i dont know how u would use a dynamic program to contol the ssc ,still working on that i would start with the bot board and
a BS2 unless u guys could help him with the code for an atom
