#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 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
- Add missing functions
- Add documentation
- Support Package Manager
