#SMBus-swift



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
