ARM7-based AutoCAD slide viewer demo

A vector graphics processing demo program written using Oberon-07 can be seen on YouTube:

The hardware used in this example is the ThaiEasyElec 'BlueScreen' board - a self-contained 320 * 240 touch-panel LCD unit driven by an NXP LPC2378 ARM7 microcontroller.

The first two images are processed in real time, the second two have built-in delays to show the drawing as it proceeds.

While the application itself is nothing special what still impresses me is the minuscule size of the resulting code. The total executable size (including startup code, runtime error trapping and reporting, UART, LCD display drivers etc.) is 17 KB. I guess I shouldn't really be surprised having written substantial software in assembler in less than 1 KB of RAM on the old 8-bit microprocessors. I must have become desensitised by the 10 MB+ sizes of the typical bloatware these days!

The AutoCAD Slide image data file sizes used in the demo are 5 KB for the Space Shuttle and 28 KB for St Pauls. They are appended to the executable and accessed conveniently from the application using the new 'resource management' feature of Armaide.
