Hi all, the Arduino MAX7219 library is working! Here a first video. Source code will be delivered as soon as it is stable.

 This time I'm playing with my Arduino UNO board, a MAXIM MAX 7219 driver and a couple of common cathode 7 segment displays.

Here is the Qt/C++ GUI source code on my Mini6410 front end. the plot diagram is a custom widget that receives the point from the network interface and shows on the grid.

Hi everybody, after a while I'm back again with another DIY project... Weeks ago I needed a simple temperature logger with low acquisition rate (30 - 60 seconds) and then I looked for some chip and board in my lab.

This tutorial provides information necessary to compile and install Qt 4.8.3 on Mini 6410 friendly ARM board. The board is equipped with the default GNU/Linux operating system (kernel 2.6.28.6).

This guide has been tested on Ubuntu 10.04 (64 bits) GNU/Linux host distribution.

Here is a first screenshot of the data logger.

Canonical founder Mark Shuttleworth revealed that Nokia's Qt toolkit will be included as a standard component in future versions of Ubuntu.
