API libraries and CLI Tools for MAG3110 sensor.

Datasheet

You may use precompilled versions or build from source

1. CMake 2.8
2. Make
3. C11 (gnu) compiler
4. I2C-supported linux kernel (all that I know)
5. git (optional) for cloning

This is generic CMake process.

First, create new empty directory:

mkdir -p /tmp/build-mag3110
cd /tmp

Then clone Git repo

git clone https://github.com/reddec/mag3110-tools.git

Use CMake for prepare MAKE files:

cd /tmp/build-mag3110
cmake -DCMAKE_BUILD_TYPE=Release /tmp/mag3110-tools

Compile and package:

make package

After build you can use one of following method:

1. Use mag3110-1.0.0-Linux.sh as self-installer
2. Use mag3110-1.0.0-Linux.tar.gz as binary tar-ball
3. Use built files directly =)

You may use static or shared library.

mag3110 [-d data rate][-o oversampling][-i interval][-l name] <device> <address>

Where:

• device (text, required) - path of I2C device (like /dev/i2c-1)
• address (text, required) - address of sensor in device in HEX (like 0x52)
• -d (type: number, optional) - positive or zero value of data rate in range [0;8)
• -o (type: number, optional) - positive or zero value of oversampling ratio in range [0;4)
• -i (type: number, optional) - positive or zero value of scanning interval in milliseconds
• -l (type: text, optional) - use output format as InfluxDB line format with this name as measurment

Format: <name>SPACE<value>SPACE<time in nanoseconds>SPACE<unit>
