# lps331-tools
API libraries and CLI Tools for LPS331 sensor.
[Datasheet](http://www.st.com/content/ccc/resource/technical/document/datasheet/40/c2/46/1e/99/22/4c/60/DM00036196.pdf/files/DM00036196.pdf/jcr:content/translations/en.DM00036196.pdf)
## Obtain
[You may use precompilled versions](https://github.com/reddec/lps331-tools/releases)
or build from source
### Build requirements
1. CMake 2.8
2. Make
3. C11 (gnu) compiler
4. I2C-supported linux kernel (all that I know)
5. git (optional) for cloning
### Build
This is generic CMake process.
First, create new empty directory:
mkdir -p /tmp/build-lps331
cd /tmp
Then clone Git repo
git clone https://github.com/reddec/lps331-tools.git
Use CMake for prepare MAKE files:
cd /tmp/build-lps331
cmake -DCMAKE_BUILD_TYPE=Release /tmp/lps331-tools
Compile and package:
make package
### Install
After build you can use one of following method:
1. Use `lps331-1.0.0-Linux.sh` as self-installer
2. Use `lps331-1.0.0-Linux.tar.gz` as binary tar-ball
3. Use built files directly =)
## Use CLI
Usage: `.lps331
[profile]`
* `device` - path of I2C device (like /dev/i2c-1)
* `address` - address of sensor in device in HEX (like 0x52)
* `profile` (optional) - Index of rates profile (see below). Default 4
### Profiles
| # | Update temperature (Hz) | Update pressure (Hz) |
|---|--------------------------|----------------------|
| 0 | 1 | 1 |
| 1 | 7 | 1 |
| 2 | 12.5 | 1 |
| 3 | 25 | 1 |
| 4 | 7 | 7 |
| 5 | 12.5 | 12.5 |
| 6 | 25 | 25 |
### Output
Space separated lines.
Pattern:
* names: `temp` and `pressure`
* units: `c` and `mbar`
* value: text view of `double` value
Examples:
temp 22.5 c
pressure 997.1123 mbar

### Linking
