                Raspberry Pi 5 - All channels on pwm0
              
          
    Hardware PWM on the Raspberry Pi 5 b

Since PWM is a little fraught with gotchas, this is mostly a message to future me-

    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

                Working asound.conf for libphatmeter on Volumio. Very hacky and still needs tweaks to mpd.conf and /dev/i2c-1 owned by group "audio" =/
              
          
    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"
