“I’ve created fire!”
The HDSP-2112 is a module with a LED matrix display which displays 8 characters with 5×7 LEDs each. Due to the high power requirement of more than 2 watts this display is not suitable for mobile devices. The operating voltage is 5 volts and it will be controlled using a 8 bit wide data bus and a 5 bit wide address bus.
I already experimented with this in 2013, however I stopped working on that and did not have a working setup ever.
This time I was more persistent – and it worked :-).
More about this along with a thorough documentation on the project page.
