Now that I'm pushing the line from "firmware" into "operating system" territory, I figured I'd give JumperlOS something any self-respecting OS needs, a color picker.

And here's what all 12 of those analog crossbar switches are up to. These are the same connections you see in the video, so if you stare at it long enough, it might make sense.

Also they just started shipping out to backers this week, I'm so stoked for people to start playing with them.

Enough already, make it run DOOM!

I already did!

Mesmerizing. 👏🏽

Yeah I figured it would be a nice thing for people to screw around with if they don't have a project to actually build on it.

This looks pretty cool I’m not even gonna lie. How does it “sniff” UART signals? I was actually working on something a while back to try and convert UART signals to I2C a while back and was pretty painful with the oscope…

It has 10 of the RP2350B's GPIO hooked up to the crossbar matrix, and 2 of them are loosely dedicated UART. The second core is running a super tight loop for the fast stuff, so if it sees any data it'll handle it according to the config (passthrough to USB, accept commands, etc.)

Be ware, this will lead to maddness. (Source: was an OS developer...)

Those who know how to build innovation ;)
