Add a UI to your standalone Raspberry Pi project using your Android or iOS phone
pip install piui
Download the piui_plus_examples.zip file from github.com/dps/piui-sdcards. Unzip it and you'll find a 4Gb sd card image named piui_plus_examples.img. Write it to an SD card by following the usual Raspberry Pi instructions. At present, this image is based on Occidentalis 0.2.
Assuming you have the same wifi adapter I do, this will work out of the box. If not, read the Pi-Point docs to configure for your own hardware.
On first boot, you can sync the latest piui source with:
cd piui
git pull origin
and start the demo app with:
python piui_demo.py
Start with the latest release of Raspbian or (better as it's ready for hardware projects) Occidentalis.
Follow the Pi-Point documentation to turn your Pi into a wifi access point. Note that if you use the Adafruit wifi adapter, these instructions do not work in full as the nl80211 driver does not support that device (which uses a Realtek chipset). This blog post explains how to make it work - thanks Paul!
Add an entry to /etc/hosts mapping the DNS name piui to the address you configured for the Pi in the step above. Assuming it's 192.168.1.1, then you should add the following to /etc/hosts
192.168.1.1 piui
Install nginx - nginx is an HTTP server and reverse proxy, we use it to multiplex requests to your app and the piui-supervisor.
sudo apt-get install nginx
Configure nginx using the config file in the PiUi github repo - copy this to /etc/nginx/nginx.conf and restart nginx.
sudo /etc/init.d/nginx restart
Get the piui source code from github
cd /home/pi
git clone https://github.com/dps/piui.git
Arrange for the piui-supervisor to run on boot.
sudo cp /home/pi/piui/supervisor/piui-supervisor /etc/init.d
sudo update-rc.d piui-supervisor defaults
Done! Run the demo app:
cd piui
python piui_demo.py
Connect your phone to the wifi AP and navigate to 'http://piui/'.
- only works for one concurrently connected phone right now
- upon reconnection, all historical updates to page elements are made in sequence - should collapse updates to the same element
