SMBus-swift is a linux library to communicate with SMBus/I2C devices through /dev/i2c.

##Requirements
Before beign able to use SMBus in your Swift code, you should install some Linux C libraries.

On a Debian-like distro:

sudo apt-get install i2c-tools libi2c-dev
	
Then you have to make sure the i2c module is active. So check or add `i2c-dev` to `/etc/modules`. Like:

# /etc/modules: kernel modules to load at boot time.
	#
	# This file contains the names of kernel modules that should be loaded
	# at boot time, one per line. Lines beginning with 	"#" are ignored.
	
	i2c-dev

##Installation
The library is being written for/on a Raspberry Pi where the Package Manager is not functional yet, so I couldn't really figure out a way to make it work with that, and you'll have to do it manually for now.
After cloning, compile your program adding the 2 system dependencies and the main file, like
```
swiftc -o MyProgram -I ./SMBus-swift/Packages/Ci2c -I ./SMBus-swift/Packages/CioctlHelper ./SMBus-swift/Sources/SMBus.swift main.swift
```
You can look [here](https://github.com/Sephiroth87/scroll-phat-swift) for some examples on how to include the library in your program.

##Usage
No need to import anything since the library is built together with your other sources.
To open the connection create an SMBus object:
```
try bus = SMBus(busNumber: 1) // opens /dev/i2c-1
```
and then send your commands:
```
try bus.writeI2CBlockData(0x60, command: UInt8(0x01), values: [UInt8(2)])
```

##TODO
- [x] Add missing functions
- [ ] Add documentation
- [ ] Support Package Manager
