Configuring the Digispark ATTINY85 board for Arduino IDE and upgrading the bootloader

Warning: this document has to be updated by pointing to https://github.com/SpenceKonde/ATTinyCore

This note describes the configuration of an ATtiny85 based microcontroller development board named Digispark and similar to the Arduino line. It is available in many online marketplaces for roughly 1 dollar (e.g., Ebay, Amazon, AliExpress) and is shipped fully assembled, including a V-USB interface (a software-only implementation of a low-speed USB device for Atmel's AVR microcontrollers). Coding is similar to Arduino: it uses the familiar Arduino IDE and is already provided with a ready-to-use bootloader (

Basic RESTful API with Symfony 2 + FOSRestBundle (JSON format only) + FOSUserBundle + FOSOauthServerBundle

The API we are creating in this gist will follow these rules :

The API only returns JSON responses
All API routes require authentication
Authentication is handled via OAuth2 with password Grant Type only (no need for Authorization pages and such).
API versioning is managed via a subdomain (e.g. v1.api.example.com)

The API will be written in PHP with the Symfony 2 framework. The following SF2 bundles are used :

	// This Cordova Hook (script) removes "AdSupport.framework" and "libAdIdAccess" references
	// from the cordova-plugin-google-analytics plugin, as well as removes it from
	// references found in the corresponding node_module and .project.pbxproj.
	// The authoritive source is found at: https://gist.github.com/SteveKennedy
