Serial Communication in Java with Raspberry Pi and RXTX

October 17, 2012

Serial communication is one of the ancient technologies in computing that is still relevant today. Its origins date back to the 1960’s when serial communication was used between teletypewriters and modems. Today, serial interfaces can be found inside myriads of embedded systems where they transfer data between different components. A serial interface is also a common way to connect a PC to an embedded system. Application scenarios include firmware update, logging/debugging, data streaming and many more. In an earlier post I introduced the Raspberry Pi as a great platform for tinkering. This post provides a short introduction in UART (Universal Asynchronous Receiver Transmitter), the basic form of serial interface. Some examples illustrate how you can set up serial connections with your Pi and how to implement them in your Java applications by using the RXTX library.

Tabris goes to EclipseCon Europe

October 10, 2012

This year Tabris will be at EclipseCon Europe. Tabris is the mobile cross platform solution that connects the benefits of RAP based web applications with the native power and intuitivity of touch based mobile devices. At EclipseCon Europe you will have the chance not only to get the big picture about the connection between the trends to mobile and touch devices and Eclipse/Java technologies, but also some in-depth information about how Tabris works and how you can leverage it in your own projects. In addition to presentations by EclipseSource, there are three talks from users sharing their experiences implementing Tabris in their projects or comparing Tabris with other state-of-the-art, cross-platform solutions.

Lessons learned when using Android's MediaPlayer and VideoView

August 24, 2012

The other day I wanted to add video playback support to Tabris. “Ha!” I thought, “Piece of cake.” My fallback strategy was the normally well documented Android API and, as a last resort, Stackoverflow with the answer to almost any question you can think of. As it turned out, none of these assumptions were correct.
