There’s surprisingly little information about this. Novation’s user guide for the Launchkey Mini has no mention of how to control the LEDs. There is some information available in a “programmer’s reference” manual for the Launchkey II (not the “Mini” version), but sadly the LED components don’t function the same way.
It required a bit of reverse engineering and the result isn’t quite as pretty, but I’ve figured out how to do it.
I’ve been trying to teach myself a little Python, and here’s what I came up with for my first small project. Using their respective APIs, I’ve built a plugin for the Prismatik ambilight software that maps live data from the iRacing simulator. A video demonstrates the end result far better than I can explain it:
The time is finally here! After a short hiatus to work on the McCree Hammershot project, I’m back to building my time circuits. The display circuit boards have arrived and it’s time to get them assembled and running!
With the LED characters in-hand, the next step is to write an embedded program to display integers and strings on the time circuit displays. The goal is to be able to set the characters for each display group based on simple variables, so doing something like displaying the time returned from a real-time clock (RTC) becomes trivial.
