Program Raspberry Pi Using Pingo #RaspberryPi #piday @Raspberry_Pi

August 15, 2014 Rebecca Houlihan


Pingo provides a multiplatform API for Raspberry Pi via pypi.python.org

Pingo provides a uniform API to program devices like the Raspberry Pi, BeagleBone Black, pcDuino etc. just like the Python DBAPI provides an uniform API for database programming in Python.

The API is object-oriented but easy to use: a board is an instance of a Board subclass. Every board has a dictionary called pins which lists all GPIO pins on the board. Each pin is an instance of a Pin subclass with attributes that you can inspect to learn about its capabilities.

The name Pingo is a tribute to Garoa Hacker Clube, where the project started (the words pingo and garoa are related in Portuguese). To our English-speaking friends we like to say that it means “pin, go!” — the main purpose of this package.

Basic usage

To use pingo, the first step is to instatiate a concrete Board. Each Pingo driver is a concrete board, for example, pingo.rpi.RaspberryPi and pingo.arduino.ArduinoFirmata are two such boards.

Pingo can automatically detect the board in most common cases. If it is running on a supported board, pingo.detect.MyBoard() returns an proper board instance. If Pingo is running on an unsupported machine (eg. a PC running GNU/Linux), it will try to find a remote Arduino using the Firmata protocol via USB and — if succesfull — will return a pingo.arduino.ArduinoFirmata instance.

Once you have a board instance, its possible to access its pins through the board.pins dict.
