Back then, the development process involved a lot of mistake making (sometimes followed by buying new hardware) on a breadboard. It feels like I ought to be able to to do better than that now.
I think I want to run a simulator on my pc. I've used LTSpice from time to time, but wondered which of the Logic equivalents people would recommend. Ideally, I'd like something that was easy to pick up (I don't see me doing this very often, so it would be a fresh learning curve every time) and that came with a reasonably comprehensive component library.
Other information: The aim of the project is to expand the DIO capability of one of my dataloggers to be able to read and write a much larger number of discrete lines. Pacing will be driven by external software and I can afford to run the whole thing slowly enough that I think I don't need the simulation to address timing issues.
Grateful for any thoughts.
