R on BeagleBoard with LCD and Android UI

After the successful installation of R in BeagleBoard XM, it is natural to come up with a concept of a calculator running R. The ingredients are simple: a small form factor BeagleBoard, a LCD screen, a simple keypad. R can run on Android but as a keypad passionate, no touch screen is better than the feel of real key punch.

As a proof of concept and also a weekend project, the R on the BeagleBoard is “bridged” across an Apache web server (also on the BB), to be accessed by an Android app which act as input device for R commands. Result returned from R is then forwarded to an 16×2 LCD screen from a previous IoT prototype with TI MSP430 MCU and a TP Link portable router with OpenWRT.

A little delay, but works.

The Android app is done in MIT App Inventor. It is a very nice graphical, easy to use, completely web based application to build Android app. No typing of code is required.
