Ubuntu toolchain setup

==The following are notes from setting up and using the development tools on a Ubuntu-11.04-i386 development host ==

There where some gotchas with getting the tools to work and the code to build. There is painful detail and screen casts at the bottom available on this blog Here I will include the important bits I think folks may find useful.

--MPLABx on ubuntu--

• mplabx doesn't like oracle jdk7.
• set JAVA_HOME, and PATH variables such that the JDK of your choosing is used.
• installing mplabx needs to be one as root and also needs the JAVA_HOME set to work correctly.
• using the MPLABx as UI to the PICkit3 by making a new project as a pre-built project and navigating to the hex file to use. Program device by right clicking on the project and selecting "program device"

--Android SDK + Eclipse + building ioio APK's--

• use import... to import IOIOlib and whatever APK projects you are building.
• be sure to set the android target to whatever you need to for your device.
• under project properties Java Compiler make sure to deselect "Enable Project specific settings"
• you may need to make a IOIOlib/res directory
• go to the Project Menu (on the menu bar) and select clean...
• then building the APK tends to work.
