3 Digit Decimal Display Example

[fjames]

This is a 3 digit decimal display I designed for a project I'm working on. It uses ROMs for the 7 Seg decoders. It uses an 8 bit counter to increment the display. The counter itself isn't anything special, but it does have an initialization circuit that took some time figure out. I attached the circuit and the Ocilligram showing the initialization timing. I'm really liking LogicCircuit. Thanks for creating it.

The initialization circuit is right in this forum: https://logiccircuit.org/forum/viewtopic.php?f=3&t=3
But looks like you've nailed it. Good job.

Thanks for the comment. I actually saw that circuit. I found other similar circuits as well. The issue I ran into was it was too fast. I needed more delay in the circuit for it to work. I tried numerous configurations and gate combinations before I found one that worked. I call this this version the "Skip a Beat" initialization circuit. - LOL
