Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

None of these suggestions worked for me, because Android was appending a sequence number to the package name to produce the final APK file name (this may vary with the version of Android OS). The following sequence of commands is what worked for me on a non-rooted device:

Determine the package name of the app, e.g. com.example.someapp. Skip this step if you already know the package name.

adb shell pm list packages

Look through the list of package names and try to find a match between the app in question and the package name. This is usually easy, but note that the package name can be completely unrelated to the app name. If you can't recognize the app from the list of package names, try finding the app in Google Play using a browser. The URL for an app in Google Play contains the package name.

For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).
1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.
2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt file dtoverlay=dwc2 on a new line, then save the file.
3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh in the SD card as well. By default SSH i

	# To Setup:
	# 1) Save the .git-completion.bash file found here:
	# https://github.com/git/git/blob/master/contrib/completion/git-completion.bash
	# 2) Add the following lines to your .bash_profile, be sure to reload (for example: source ~/.bash_profile) for the changes to take effect:

	# Git branch bash completion
	if [ -f ~/.git-completion.bash ]; then
	. ~/.git-completion.bash

	# Add git completion to aliases

	console.log('Loading event');

	var Q = require('q');
	var aws = require('aws-sdk');
	var cloudfront = new aws.CloudFront();

	exports.handler = function (event, context) {
	//_log('Received event: ', event);

	var bucket = event.Records[0].s3.bucket.name;

	// To unzip the epub, move the ePub to a folder, cd to it then simply:

	unzip MyEbook.epub

	// To zip up an epub:
	1. zip -X MyNewEbook.epub mimetype
	2. zip -rg MyNewEbook.epub META-INF -x \*.DS_Store
	3. zip -rg MyNewEbook.epub OEBPS -x \*.DS_Store

	Some explanations necessary here. We start each line with two flags:

	brew update
	brew install pyqt geos spatialindex
	easy_install pip
	pip install virtualenv

	cd Development/Others\'/
	mkdir FlatCAM
	cd FlatCAM
	virtualenv env
	source env/bin/activate


	module MyExt
	refine String do
	def foo
	"foo"
	end
	end
	end

	class Parent

	To control iBooks, you can activate VoiceOver, mute it (as you don't actually want voice),
	select the page progress bar, and then use up/down keyboard buttons.

	You can set Settings→General→Accessibility→Accessibility Shortcut = VoiceOver to set
	triple-click of Home to (de-)activate VoiceOver.
