Matrix driver for HDSP-200x four character 5x7 alphanumeric displays. These are 12 pin DIL package ICs full of LEDs arranged in 4 characters of 5 columns & 7 rows each. The ones I have are the yellow HDSP-2001, but they are also available in red (HDSP-2000), high efficiency red (HDSP-2002) or green (HDSP 2003). I don't know if they are easily available anymore, but I thought, since I've got 30 or so, I'd have a go at programming them. See my notepad (http://mbed.org/users/tonymudd/notebook/led-matrix-display/) for videos of this working.

An "A" is defined like this (for a 5x7 array)
x = 00100 = 0x04
x x = 01010 = 0x0A
x x = 10001 = 0x11
x x = 10001 = 0x11
x x x x x = 11111 = 0x1F
x x = 10001 = 0x11
x x = 10001 = 0x11
so we could define A like this
unsigned char A_DATA[7] = { 0x04, 0x0A, 0x11, 0x11, 0x1F, 0x11, 0x11 } ;
or we could draw a picture and let the preprocessor do the work for us
#define __x__ 0x04 // __x__ = 00100, so there will only be 32 patterns
#define _x_x_ 0x0A // to define
#define x___x 0x11
#define xxxxx 0x1F
unsigned char A_DATA[7] = { __x__,
_x_x_,
x___x,
x___x,
xxxxx,
x___x,
x___x }
now this is much easier to fiddle with if we want to
define a slightly different look (no need to sketch it
out, find the binary, then the hex.
