The LSS will not take PMM, PPM, or S-BUS directly.
At the moment the only way to control it is by sending a direct PWM (RC) to the servo.
One could use such PPM receiver and connect to, let’s say, an Arduino microcontroller.
A piece of code could decode the PPM (we have a library for that) and then split and send the signals to the servos in Smart mode so daisy-chained.
I found this idea quite interesting and went ahead in coding a simple solution that can take the PPM input and convert it to a serial control of the LSS’s. Please forgive my workspace…
I’ve already added this example code to the “Arduino-PPM” library on Arduino.
I’m actually thinking of using the Radiolink set-up. I do not see a power connector to your rx, how are you powering the set-up? Are you using just one of the LSS power hub? What is the output 12V nominal?
Can I use the LSS - Adapter Board, connected to the LSS servos in series, power via a external power pack and use a remote control similar to your set-up?
I’ve updated our Arduino PPM library to include that new example.
In the setup I put together for this video, the LSS-2IO Arduino Compatible board was used and will supply a regulated 5VDC to the RC Receiver.
The power source is 12VDC for the LSS and can be hooked up different ways.
The LSS’s servos are supplied with one Serial cable and one RC cable, one could use the RC cable to supply voltage.
It can be used with the LSS-HUB which has a barrel connector for a wall adapter (12VDC and sufficient current).
I used the LSS-Adapter with our XT60 wall adapter but that’s just more convenient for me.
I realize now the thought I had will not work, just using the LSS- Adapter Board (Type-C), since there is no I/O for the PPM pins on the receiver. I like the XT60 Power adapter and thought that would be better for my project vs a battery pack.
Correct, the LSS Adapter is a serial adapter and power distribution board for multiple LSS’s.
If money is not an issue, you can buy both the LSS-Adapter and connect an LSS-2IO board, that’s what I’m using in my example.
Thanks for the info, I’m working with the servos now and am using the LSS Config via USB-C, is there a tutorial on how to set-up the servos? I have the LSS adapter board plugged in to a 12V power supply, the servo flashes green then red, the nothing. Just wondering how to assign ID# for starters and be able to set-up the servos.
I copied your setup with the hardware, I also noticed I need to turn off or disconnect the Rx for LSS config to scan and find a servo.
All servos are connected in serial mode, assigned IDs 1-3. It only finds ID 3 each time, which is the last servo in the chain.
As I noted in another thread, the RC PPM mode works but maybe I missed your note on whether or not I can leverage the saved servo settings via LSS config with this option? Is that possible? Right now the dead band for one joystick is too sensitive, say you try to pan but the roll or tilt also is very jerky when moved.
When I move one servo in LSS config, adjusting the speed and etc, the end result is what I desire.
