Use Raspberry Pi as a schedulable timer for GPIO hardware, configurable over the web. Depends on WiringPi.

This is the software for the pool timer project described at http://upon2020.com/blog/2012/12/my-raspberry-pi-pool-timer-why/

This should run on any Linux-based OS that runs on the Raspberry Pi, but you will have to manually put all the files in the right place, including creating the configuration file from the template.

If you run UBOS, it's much simpler.

Step 1. Upgrade UBOS to the latest, and install the tools and dependencies you need:

> sudo pacman -Syu
> sudo pacman -S git base-devel wiringpi

Step 2. Clone this repository:

> git clone https://github.com/jernst/rasptimer.git

Step 3. Build the rasptimer package with:

> cd rasptimer
> makepkg -c -f

Step 4. Install the rasptimer package:

> sudo pacman -U rasptimer-*-any.pkg.tar.xz

(There's a wildcard so it works with future versions as well)

Step 5. Create a site that runs rasptimer:

> sudo ubos-admin createsite --ask

and answer the questions in the way that is appropriate for you. E.g:

> ubos-admin createsite --ask -n
