For those, like me, who have been doing Java for a long time, it is truly amazing that Java lets us effortlessly drop down to the 0/1 bits and hardware level.

I had no experience of Raspberry Pi, and just a few hours of exploring and programming allowed me to control a cascade of five 7-segment LED displays.

Here's a detailed article of my experience:

The ease with which the above was made possible is, admittedly, in part due to the existence of the Pi4J library for the Rpi.

Does anyone know of any other techniques to hit the Raspberry GPIO pins without using Pi4J?
