# pyGI/webGI - A Web interface for the Granz Scientific Raspberry Pi Zero Geiger Counter

Python/HTML5/CSS/JS/Websocket software suite for collecting, distributing,
monitoring, mapping and analyzing ionizing radiation counts detected by the PiGI-Module.

This software stack is based on the Raspberry Pi Geiger Counter project described here:

http://projects-raspberry.com/pigi-raspberry-pi-geiger-muller-interface/

and here:

https://apollo.open-resource.org/lab:pigi

## Installation

### Dependencies

We've tried to keep external dependencies to a minimum to make it easily
deployable on any flavor of open-source operating system. If you deploy it
successfully on any other OS, please update this:

#### Currently tested versions

* greenlet-0.4.2
    * bottle-0.12.4
    * gevent-1.0
    * gevent-websocket-0.9.3

#### Ubuntu/Raspbian

$ sudo apt-get install python-pip python-dev libevent-dev
    $ sudo pip install ez-setup
    $ sudo pip install leveldb greenlet bottle gevent gevent-websocket

#### Raspberry Pi deployment

If you want to deploy the code on a Pi for production in order to count
values from a real GM tube connected to the Pi, you have to make sure to
satisfy the RPi.GPIO dependency:

* pip install RPi.GPIO

This only applies to non-Raspbian installations, since Raspbian ships
RPi.GPIO with the default installation.

### Clone repo

$ git clone https://github.com/granzscientific/pi-zero-geiger-counter.git

## Configuration

PyGI checks 3 configuration files, if existent in conf/, updating the
values defined in the file before or using new ones, in the following order:

* default.cfg (automatically comes shipped per default with examples)
    * local.cfg (create this file to override local server settings - gitignored)
    * dynamic.cfg (this file will be created automatically,
      if the webGI client wants to change server settings - also gitignored)

When you are deploying on the Pi to count real values and/or want to
change the Web Server/Socket port to 80 rather than 8080 __you have to
run the software as root__. Otherwise the interrupt handling on the Pi
won't work and port 80 will not be accessible due to security (<1024).

## Usage

### Server Startup

$ cd PiGI/
    $ ./pyGIserver.py

### Client Access

Open Browser and goto http://localhost:8080
