## Software

### Install
Before run, enable I2C on Raspberry Pi. (`sudo raspi-config`)
Then, you can find the i2c devices like this.
```
> sudo i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- 48 49 4a 4b -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
```
If you will use an old raspberry pi, run `sudo apt install libatlas-base-dev` to use `numpy` (This tool doesn't depend on `numpy`).

Then, type `pip3 install rubis`
The `rubis` binary will be provided at `~/.local/bin/rubis`
You want mysql store, please see `Database setting` below.


### Usage
When you execute `rubis` without option, logging immidiately starts with default configurations.
You can use your custom configuration file with `-c` option.

`rubis -g` generates template config file.
Edit them, then run `rubis -c custom_config.json`.
At the **strong** request of the author's supervisor, the following commands are available to people in CYGNUS (dark matter search experiment) without creating or editing a new configuration file.
```
rubis -c cygnus
```
In addition of `cygnus`, `one_board` and `mysql` configurations are pre-defined.

Some configurations can be overwrited with command line options.
`rubis -h` provides option descriptions.
The output file format is CSV/MySQL.

As a default, the csv files like `sc-20211029-75enrt.csv` are created.
The `75enrt` is a unique hash created by configurations.
The hash helps separation not to mix files taken with different configurations.
The CSV format is like that.

The `-r` option makes "dry-run".
With the option, this rubis works on general system not raspberry pi even without ADS board.
It helps to know how rubis works.

The `-l` option show rubis log.
It helps to find the logfile place and configuration with hash.

The `-q` option kill all rubis processes.
With the `-s` option, rubis uses the stored cofiguration used in the previous run.

For analysis with pandas dataframe, it is easy to extract the csv files.
```
import pandas as pd
from glob import glob

hash_str = '75enrt'
df = [pd.read_csv(name, parse_dates=[0], index_col=0) for name in sorted(glob('./*'+hash_str+'.csv'))]
df = pd.concat(df)
```

If you select `naming` including "date", a new file will be created day by day.

The sources should be set like,
```
"1":{
    "name": "ch1",
    "description": "channel 1",
    "type": "volt"
    },
"2":{
    "name": "ch2",
    "description": "channel 2",
    "type": "linear"
    "a": 2.0,
    "b": 1.2
    },
```
The `name` is used for csv header. For the `type`, `"volt"`, `"raw"`, `"millivolt"`, and `"linear"` are available.
`"linear"` returns the value `"a" * (volt) + "b"`. The "a" and "b" should be written in the config file, for each sources.


## Database setting
If you want database store, do like that additionaly
```
sudo apt install mariadb-server
sudo mysql -u root
MariaDB [(none)]> UPDATE mysql.user SET password=password('newpassword') WHERE User = 'root';
MariaDB [mysql]> UPDATE mysql.user SET plugin='' WHERE User='root';
MariaDB [mysql]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' identified by 'newpassword' with grant option;
MariaDB [mysql]> exit
sudo systemctl restart mysql
```
You need an external access, please make a user.
```
CREATE USER 'rubis'@'10.37.%' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'rubis'@'10.37.%';
FLUSH PRIVILEGES;
```
And comment out the `bind-address` line in `/etc/mysql/mariadb.conf.d/50-server.cnf`.
In addition, add `default_time_zone='+00:00'` at the bottom of the file.
Then run `sudo systemctl restart mysql`.

If you need static IP access, please edit `/etc/dhcpcd.conf` like this.
```
# Example static IP configuration:
interface eth0
static ip_address=xx.xx.xx.xx/23 # your IP
static routers=xx.xx.xx.xx # your gateway
static domain_name_servers=xx.xx.xx.xx xx.xx.xx.xx # your DNS
```

When you set `"db"` or `"both"` for `output` in config file, the following settings are required.
```
"db":{
    "login":{
        "host": "127.0.0.1",
        "port": 3306,
        "user": "root",
        "passwd": "newpassword",
        "autocommit": true},
    "name": "rubis"
    }
```
