I was running @bluntbody's new Joystick/Display python example code and noticed that the display refresh rate was a lot slower than it should be.
It turns out that this was due to a bug in the USBControl sketch, which is what handles communication between the modulo controller and the python program. I've checked in a fix for it that. It roughly doubles the frame rate, from about 12fps to around 24fps!
To get this fix, you'll need to download the latest version of the USBControl sketch from github and use the Arduino app to flash it to the controller. The fix will also be included in the next release of the modulo arduino library.
Note that even though this is installed with the Arduino app, the bug only affected python programs.
