Cyclone II-Exp.7 – follow up, follow up


Okay, I couldn’t help myself, let’s shift the enabled segment.

Without looking ahead and doing some interwebything searching and head scratching:

Rotate around the segments

Rotate around the segment enable

The exercise for the reader is to take this example, expand the LED enable to a shifting register and rotate through each segment of each 7-segment display.

RTL for this looks like:

Rotating of enabled segment with additional register.

Rotating of enabled segment with additional register.

… rather than the preceding one without the rotating enable.

The main difference is the presetting of the first one we tackled versus the rotation through the register in the one in the picture above.
