Fader Bank

No, there is no wiring diagram. I made an improved new version on GitHub. Some instruction you can find as a comment in the code.
The only recommendations for fader is a 10k Ohm linear. There are many versions on the market, you need to choose the right one for yourself.

How would I edit your code to allow the buttons alongside each fader to behave as a bump button, like they do on an ETC Element?

I assume you think of Element 1, which have only one button per fader. Have also a look to the Readme.

Using submaster class, no initialization needed:
Submaster submaster1(A1, 2, 1); // make submaster 1 using Analog pin A1 for leveler and pin 2 for the fire/bump button

Using fader class:
Fader fader1(A1, 2, 0, 1); // make fader number 1 using Analog pin A1 for leveler and pin 2 for the fire/bump button, no stop button



Ok, thanks very much. The code works great, as does the capacitor trick to reduce noise!

I am now having trouble with it when I change "/eos/fader/" to "/eos/submaster/"

It no longer controls the submasters in Eos when I do that.

Do you happen to have a copy of the code for submasters?

What did you mean you changed /eos/fader/ to /eos/submaster/ ?
Submaster is an own class.
Did you programmed a submaster in EOS. Submaster access direct to the submaster in the submaster list.
What says the diagnostic Tab99?

Embarrassingly I had written /submaster/ instead of /sub/ 

It is working now

Did you tried the eOS-USB library?
