Multi controller example

[octave]

Hi,

Thank you for this awesome work that you've done. I was wondering if you have already written best practices and/or a guide on how to implement/connect multiple modules of 4 faders to control faders configuration of 8, 12, 16, etc for example?

I haven't written any guides for this, but I'll quickly share some guidelines:

To connect multiple ATmega328Ps to one central microcontroller, you can use I²C. You should give each ’328P a different address:

Control-Surface-Motor-Fader/Motor-Controller/main.cpp

Line 114 in 81fd2fc

static constexpr uint8_t i2c_address = 8;

In the motor controller sketch, you should then add more PBValue instances (one for each fader), and make the fader_index and slave_addr constants variable. This requires a bit of refactoring, but it shouldn't be difficult.
