#Favor

Favor is a javascript/node.js library to abstract away complex and inconsistent hardware interfaces into a single simple to use API.

Have you ever wanted to write

$$('temperature').get(function(temp) { console.log('The temperature is ', temp) };

Well, now you can, and run on multiple devices without mixing business logic with device configuration considerations.

Check out the demo video of getting started with Favor.

In this sense, hardware agnostic means that you can write your business logic without needing to worry about what hardware it will run on.

Currently Favor works with linux based devices like the Raspberry Pi, Beaglebone and others. But more than just the hardware platform, with Favor you can run your application on different chips and sensors, without needing to consider what type of chip the application is runnning on, or even what protocol (gpio, I2C, SPI).

Favor makes it possible to run your application on completely different hardware.

Other platforms are currently in the process of being supported, and more protocols can be added as well. Need something special? Just ask!

Favor has been tested with node v4, it should also work with v5. v0.10 and v0.12 have not been tested and may not work.

Currently Favor has been tested on RaspberryPi v1b and Beaglebone Black, but any linux device which runs node.js should work. I'll be happy to test with other devices, I just need to get access to them.

Favor works with GPIO, i2C and SPI protocols.

Favor uses a js configuration file stored on your device which describes the structure of your hardware. It queries this js file, similar to how jQuery parses and interacts with the DOM. Once Favor knows what devices are connected, and how to interact with them, you can easly write jQuery style statements like $$('temperature').get(callback) will get you the temperature on any device running Favor which has a temperature sensor.

1. a single consistent api for interacting with different devices and protocols

2. a separation of concerns between hardware and software

3. write-once run-anywhere

4. testable logic which will run across different hardware devices
