#lighthack Box mod in a case - Help Please. I don´t get it.

Can you please post the code as a .zip file

Yes. But because nothing worked, I only have the original file

with the additionally defined button and potentiometer.

You are on a complete wrong way look at https://github.com/sstaub/eOS
For faders you need an analog pin.

OK. That's easy to change.
Used A21 / A22 for the potentiometers now.
But unfortunately it ends there.

I meant 11/12. My mistake.

The code you send have nothing to do with my library you need to use.

That´s right. I´ve meant the "original" file that u can download for the BOX1 KIT from the ETC Shop.

It was not clear to me that it´s not possible to add some "features". 

I think it went in the right direction now. I used the "classic" code ´cause i didn´t understood where to plug the LCD in. I had no clue that your library is different and how it works. So...At this point: It runs with your BOX2B Code as it should.

As an advice, with an Arduino MEGA you can use much more parameters than on UNO.

Thank u so much sstaub!

I was able to add the potentiometers to the code!

1.) Have to figure out why they only turn up to 70 instead 100. 

2.) How to use more parameters. Tried to delete the // for CTO but gave me an error.

Potts must 10k linear, I don't know why this happens.
#define PARAMETER_MAX 14 (line 70) must mach the number of configured parameters.
If you use 20 parameters (including empties) change to #define PARAMETER_MAX 20

Maybe you connected the pots to 3.3V instead of 5V

You‘re right. I saw it later. Works perfectly on PC. On my surface…not so. Everything beside the Potentiometer. Would u recommend a extern power supply for this project? Not sure if a active usb hub would do its job.

I think two USB devices are two much. But I'm a Mac user.
