Systemd unit for managing USB gadgets @Raspberry_Pi #PiDay #RaspberryPi
Super handy post by by Lars Kellogg-Stedman up on Odd Bits.
The Pi Zero (and Zero W) have support for acting as a USB gadget: that means that they can be configured to act as a USB device — like a serial port, an ethernet interface, a mass storage device, etc.
There are two different ways of configuring this support. The first only allows you to configure a single type of gadget at a time, and boils down to:
Enable the dwc2 overlay in /boot/config.txt
This process is more fully documented here.
The second mechanism makes use of the libcomposite driver to create multifunction gadgets. The manual procedure is documented in the kernel documentation. While it’s a useful feature, the configuration process requires several steps and if you only do it infrequently it can be easy to forget.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
