Have PI / ARDUINO R3 set up. - works OK eg ' HELLO WORLD ' on LCD display.
Have updated to 1.0.5 OK and have JAVA 7 selected.
When attempting to add downloaded library [ adafruit example for I2C driven LCD via GIT-HUB ] to existing libraries in / usr / share/ arduino / libraries I get JAVA type errors.
Have downloaded latest LINUX32 as zip file called processing-2.1.1-linux32.tgz and understand that I need to replace x86 Java runtime with RASPBERRY PI armhfone.
On attempting to unzip using tar xvzf processing-2.1.1-linux32.tgz I get error message gzip : stdin : unexpected end of file
Any suggestions ? Thanks
