Raspi.js
==========
[](https://gitter.im/nebrius/raspi-io?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
Raspi.js provides initialization and base support for the Raspberry Pi. This module, along with [Raspi Board](https://github.com/nebrius/raspi-board) and [Raspi Peripheral](https://github.com/nebrius/raspi-peripheral), provide support for various peripherals on the Raspberry Pi. These libraries form the basis for [Raspi IO](https://github.com/nebrius/raspi-io), an IO plugin that adds support for the Raspberry Pi to [Johnny-Five](https://github.com/rwaldron/johnny-five).
Check out the following peripheral API modules:
* [Raspi GPIO](https://github.com/nebrius/raspi-gpio)
* [Raspi PWM](https://github.com/nebrius/raspi-pwm)
* [Raspi Software PWM](https://github.com/tralves/raspi-soft-pwm)
* [Raspi I2C](https://github.com/nebrius/raspi-i2c)
* [Raspi LED](https://github.com/nebrius/raspi-led)
* [Raspi Serial](https://github.com/nebrius/raspi-serial)
If you have a bug report, feature request, or wish to contribute code, please be sure to check out the [Raspi IO Contributing Guide](https://github.com/nebrius/raspi-io/blob/master/CONTRIBUTING.md).
## System Requirements
- Raspberry Pi Model B Rev 1 or newer (sorry Model A users)
- Raspbian Jessie or newer
- [Node-RED](http://nodered.org/) works, but can be finicky and difficult to debug.
- See https://github.com/nebrius/raspi-io/issues/24 for more info about support for other OSes
- Node 4.0.0 or newer
Detailed instructions for getting a Raspberry Pi ready for NodeBots, including how to install Node.js, can be found in the [wiki](https://github.com/nebrius/raspi-io/wiki/Getting-a-Raspberry-Pi-ready-for-NodeBots)
**Warning:** when using this module, it MUST be installed with user-level permissions, but run with root permissions (e.g. `sudo node index.js`).
## Installation
Install with npm:
```Shell
npm install raspi
```
**Note:** this project is written in [TypeScript](http://www.typescriptlang.org/) and includes type definitions in the package.json file. This means that if you want to use it from TypeScript, you don't need to install a separate @types module.
## Example Usage
In TypeScript/ES6:
```TypeScript
import { init } from 'raspi';
import { DigitalInput, DigitalOutput } from 'raspi-gpio';
init(() => {
const input = new DigitalInput('P1-3');
const output = new DigitalOutput('P1-5');
output.write(input.read());
});
```
in JavaScript:
```JavaScript
const raspi = require('raspi');
const gpio = require('raspi-gpio');
raspi.init(() => {
const input = new gpio.DigitalInput('P1-3');
const output = new gpio.DigitalOutput('P1-5');
output.write(input.read());
});
```
