pi_cam

A raspberry pi camera project. I plan to have / do have the following features:

• log temperature to a log file and web page

• show temperature on an lcd panel

• monitor jenkins and show a red light if any test is failing

• monitor jenkins and show a yellow light if any test has bad QA

• monitor jenkins and show a green light if all tests are in good state

• push button on front of device to power down OS

• Setup

You need to install these:

sudo apt-get update
sudo apt-get install figlet python-imaging-tk git nginx python-virtualenv \
    python-dev uwsgi uwsgi-plugin-python supervisor

Due to this issue: raspberrypi/linux#435

You should set your /etc/modules to look like this:

w1-therm
w1-gpio pullup=1
i2c-dev
i2c-bcm2708
spi-bcm2708
snd-bcm2835

Alternatively or additionally you should run

sudo apt-get install rpi-update

Then clone this repository to your pi e.g.:

cd
git clone git://github.com/timlinux/pi_cam.git

Now setup a virtualenv. We will host the web server component with django, uwsgi and nginx.

cd ~/pi_cam
virtualenv venv
source venv/bin/activate
pip install -r REQUIREMENTS.txt

echo "daemon off;" | sudo tee -a /etc/nginx/nginx.conf

cd /etc/nginx/sites-available
sudo rm default
sudo ln -s /home/pi/pi_cam/server-conf/nginx-site.conf default

cd /etc/uwsgi/apps-available/
sudo ln -s /home/pi/pi_cam/server-conf/django_project_uwsgi.ini default
sudo ln -s ../apps-available/default .

cd /etc/supervisor/conf.d/
sudo ln -s /home/pi/pi_cam/server-conf/supervisor-nginx.conf .
sudo ln -s /home/pi/pi_cam/server-conf/supervisor-uwsgi.conf .

Edit /etc/default/uwsgi and set:

# Run automatically at system startup?
RUN_AT_STARTUP=no

Run manually

cd ~/pi_cam
sudo python controller.py

Note: Needs to run as root for access to /dev/mem

Run automatically on boot

cd ~/pc_cam
cd /etc/init.d/
sudo cp ~/pi_cam/picam .
sudo chmod +x picam

Now either reboot or do:

sudo /etc/init.d/picam start
