# testHDSP2000 #
Small sketch for the Arduino to display characters on an HDSP2010.
Any of the displays in the HDSP2000 series should work
(they're different colours).
This is a 5x7 matrix LED display originally made by Hewlett Packard.
It appears as a 28-bit shift register (4 digits of 7 rows each)
and 5 column driver inputs.
The columns are driven by five PNP transistors configured as high-side drivers
and connected to Arduino pins 4, 5, 6, 7, and 8.
The shift register input is connected to Arduino pin 2 and
the clock to Arduino pin 3
