Frank, that’s something I want to add too. Some of the work is in place already, actually. It’s a big task, and I’m breaking it up into pieces that can be added over time. The flip-flops, for instance, are an abstraction that works exactly the way you describe. The gates and connections are there in the simulation. They’re just hidden behind a custom skin in the editor.

I bought a copy of Logicly, the big feature I would like is the ability to save a collection of gates into a more abstact device. Like taking the collection of gates and wires that make up a full adder and hiding all of the internal connections.

That would make it simpler to build complex circuits by building on previous work.

Roy, a bilateral switch looks like a challenging one to implement, since its connections can be both input and output, but it’s certainly possible that I could add it in the future. I’ll write it down and keep it in mind for future versions.

I’ve been playing around with your Logicly.It’s pretty cool!
I’ll certainly be watching.
I’ve been working on a project that requires logic gates connected to
a BILATERAL switch. This appears to only be available in mixed simulator programs with bloated overhead and a fairly long and steep learning curve.
I’ve looked at a number of apps that are similar to yours but none allow
this type of switch.What are the chances in the future?
Have any suggestions?
My idea of a work around isn’t very suitable .

Len, thanks for the suggestions. I will certainly consider all of them. A couple of notes:

1) I plan to add text objects, for exactly that reason.
2) Yes, a mess of wires sucks. I haven’t quite figured out how I want to fix that issue, but be assured, it’s something I plan to address in the future.
4) Flip-flops are on the way! I have a couple working in an internal build right now.

Nice application! I had built one like it for the TRS-80 Color computer almost 30 years ago. I’m toying with putting together a WORKING microprocessor using Logicly and would share these thoughts:

1. It would be nice to have labeling capability. I want to be able to draw frames and place labels within them That way, I can identify the accumulator, program counter, each instruction, etc.

2. I like the flexibility (pun intended) of the wires but it would be nice to force a wire to be straight. I want to be able to have address and data buses using parallel wires instead of the spaghetti I’m ending up with.

3. A tri-state buffer would alleviate these hellacious “or gate” cascades that I’m forced to use for instruction or memory select circuits.

4. Flip-flops would be a great addition! You have any idea how many of them I’ve been building by hand? That would save me the most components.

5. Programmable components! My project had a scalable DIP package (you could select an even number of pins) and a rudimentary programming script that allowed me to make shift registers, counters, almost anything I wanted. Right now that would alleviate the daunting challenge of creating more than a dozen bits of selectable memory!

Nice interface though! easy to use!

Just a massive thankyou – this has brought logic gates alive for my A level students – a fab app. Can I have your permission to download the SWF file for those classrooms without internet access?
