To save your time my question is going to be easy to answer with a simple YES or NO.
The SSC-32 has four inputs: “Inputs = 4 (Static or Latching, Analog or Digital)”.
Can these inputs read the outputs (channels) of a hobby RC receiver?
In our case the receiver is the Futaba R617 FS 2.4 GHz (only for reference).
Further explanation: We are building a prototype platform for a UAV using a PC-104 board. We would like to get the signals from the RC receiver into the PC-104 for analysis before sending commands to the servos.
I know I said that i shall keep it simple (yes or no) but the answer to the next question might help us a lot.
If the inputs of the SSC-32 can’t read the signals generated by the RC receiver, how could we get the signals to the PC-104? Ideas? Suggestions?
I do not know much about the PC-104, but a quick look up on one site the described one of these systems it sounded like on that system it had 16 digital IO lines that could input transitions. If so can you capture these signals fast enough to measure the pulse widths? I have done this on the Basic Atom Pros.
Well i was referring to the SSC-32 inputs. The PC-104 is a standard used in industrial computing. In a simple sentence i could say they are rugged SBC (single board computers) designed mainly for industrial control (and not only). The inputs and outputs of these boards are generally standard ports made to be connected to other boards for communication (serial, USB, etc). So getting the RC signals directly on the PC-104 is probably harder than protyping microcontroller board that does only that. The problem of prototyping a microcontroller board for reading RC signals is time, in our case. We are behind schedule and it was not planned in the first place. Either way, my question was only if we can read the RC channels with the inputs of the SSC-32.
BTW, i am shocked about the fast response! Thanks!
Kurte’s answer is correct. You can not read the R/C receiver signals from the SSC-32 analog inputs. You need digital inputs for these signals so you can read the PWM signals from the R/C receiver. This can not be done with the SSC-32.
Perhaps you could be specific as to the “signals from the RC receiver” to which you are refering. If it is the pulses going out to the servos, then generally no. These pulses are probably much faster than the ssc-32 resolution time (check the ssc-32 owner’s manual). That being said, you could make an RC circuit that the servo pulses could charge and get a crude analog voltage output ~porportional to pulses. Possibly a little more refined would be to use the internals of an inexpensive servo which has a 0-100% pwm output.
