Overview

Serpent Kivy Controller

This is a quick project to build a serpent controller using the Nexus 10 tablet. Kivy was chosen as a platform because it is device independent, and yields rapid results, however it has shortcomings in that it can be a slow driver for the Serpent. In the future an approach which makes use of the BeagleBoard or is written in java may be a better fit.

Installation

To install on any computer, follow the Kivy installation instructions. Then run the main.py application using the kivy command.

Android Installation

To create an android apk download the Kivy Python for Android virual machine. You can run this virtual linux instance using VirtualBox.

You will need to install mercurial in the virtual machine, and clone the code into the home directory.

$ sudo apt-get install mercurial
$ hg clone https://bitbucket.org/devries/serpent-kivy

Next you will need to create a build environment:

$ cd ~/android/python-for-android
$ ./distribute.sh -m "openssl pil kivy"

Then create the apk from within the build environment:

$ cd dist/default
$ ./build.py --package com.idolstarastronomer.serpent --name serpent \
--version 0.2 --dir ~/serpent-kivy --permission INTERNET debug

The apk is now in the bin subdirectory with the name serpent-0.2-debug.apk. You can install this into an android device using the command

$ adb install bin/serpent-0.2-debug.apk

Alternative Android Installation

You can avoid the build process, by installing the Kivy Android Launcher from the play store. Then you will have to copy the source directory to /sdcard/kivy on the android device.

I have not yet tested this method.
