This is a horrible, hacky, proof of concept mess for Pi VU Meter on Volumio It details steps with the old phatmeter library, but should work with PiVuMeter too, simply change "ameter" to "pivumeter" and link the right lib accordingly

udev rules permissions

REQUIRED: Create /etc/udev/rules.d/60-i2c.rules with the contents:

KEREL=="i2c-1", GROUP="i2C", MODE="0777"

# NOTE! This file replaces __init__.py in the Unicorn HAT HD library and allows it to drive two displays side-by-side,
# in this configuration: https://twitter.com/Gadgetoid/status/883259931478155264

# Both HATs are connected to Mini Black HAT Hack3r boards- the right board is connected directly to the Pi, and the left
# board is wired to the GPIO outputs of the right using the standard UHHD pinout: https://pinout.xyz/pinout/unicorn_hat_hd

# MISO is not needed, and the chip-select pin is jumped from BCM7 on the right header to BCM8 on the left.

Preface

I owe my very rapid learning journey in the world of ConfigFs to several key sources which aren't necessarily relevant to this result, but I feel deserve a mention anyway.

• This really demystified configfs for me, and stopped me being afraid of it: http://events.linuxfoundation.org/sites/events/files/slides/USB%20Gadget%20Configfs%20API_0.pdf
• I borrowed heavily from this Mindstorms EV3 script: https://github.com/ev3dev/ev3-systemd/blob/ev3dev-jessie/scripts/ev3-usb.sh
• Desperately trawled this thread for answers: https://answers.microsoft.com/en-us/windows/forum/windows_10-networking-winpc/windows-10-vs-remote-ndis-ethernet-usbgadget-not/cb30520a-753c-4219-b908-ad3d45590447?auth=1
• This guide is handy: http://irq5.io/2016/12/22/raspberry-pi-zero-as-multiple-usb-gadgets/
