If anyone is curious how the Jumperless takes in a list of connections over serial and figures out how to connect the crosspoint switches to make that happen. I've just posted a high-level walkthrough so you don't have to read through ~10,000 lines of code to get an idea of what's going on.

hackaday.ioṬ̴̯̿̂h̶̫̏̀ę̵̙̒ ̷̩̉C̴̖̞̀͝ọ̵̬̎̔ḓ̵̓e̸̥̞̓̓ | Details | Hackaday.io<p>I'm going to do a high-level explanation of what the code in the Jumperless is actually doing. There's a lot going on and it's in a bunch of separate files so I think it will be helpful for people who what to understand or improve upon it.</p>

<h1>General terms</h1>
<p>I've made up terms for things here that may or may not be the formal definition, so I should probably let you know what I chose.</p>
<p><strong>Breadboard Chips</strong> - This refers to the 8 CH446Q crosspoint switches (labeled A-H) that have their Y pins connected to the breadboard. This excludes Chip L which actually has it's X pins
