iRacing Plugin for Prismatik

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 plugin itself is open source and hosted on GitHub. Click here to download the latest version.

Measuring Adalight Framerate from Prismatik

Now that I’ve calculated the theoretical framerate limits, it’s time to measure the actual framerates my Adalight device is putting out.

Using a logic analyzer and an Arduino Nano, I’m going to measure the framerate at varying Prismatik “Grab Intervals” and baud rates, and compare those numbers to what my calculations predict will happen.

Custom Serial Baud Rates in Prismatik

Since I’m experimenting with increasing Adalight framerate, the first step was to try driving the Arduino Nano with a faster serial baud rate.

Unfortunately, Prismatik only supports three baud rates: 9600, 57600, and 115200. But after talking with Patrick Siegler, he pointed out a way to use your own custom baud rate for Adalight or Ardulight devices.
