8x8 LED Matrix for the PICO

I just finished prototyping an 8x8 5mm LED matrix that has
a mounting area for my PICO1TR. The matrix charlie-plexes
nine I/O lines to drive the LEDs.

The pictures of the board and a demo video are at
I will be posting the schematic, the C library and the demo sketch
in the next couple of days.

For this demo I wrote a Perl script that will convert
an ASCII representation of the LED matrix into a C data structure.
I use this utility to quickly create the characters shown in the
demo. Using a text editor I created ASCII pictures of the characters
using asterisks and spaces. The script then outputs the .c and .h
file containing the data. Each character consumes 8 bytes of flash.
