I have been playing with the Adafruit CircuitPython for a while now on the PyGamer board . Using the Adafruit libraries to light up the NeoPixels and to display pictures and text on the screen.
Then I learned that the Hackaday Supercon attendees would be given an Adafruit Edge Badge along with the official badge. This had a built in microphone which sparked my interest on creating an audio spectrum waterfall plot of the measured frequency.
This was a bit of a problem because the library that python uses to perform the Fast Fourier Transform (FFT) did not have a CircuitPython port. So I decided to write my own code in CircuitPython to compute the FFT. Now I could have written C code to run underneath, but I have not gotten to that point yet, and also wanted to get this done for Supercon, which required a few other parts, so that drove my decision to just use pure Python.
I have really enjoyed using CircuitPython, as it is a much simpler method to playing with microcontrollers than Arduino. The ecosystem that Adafruit has developed makes it a breeze for developers, new and old, to quickly get a project off the ground and running. I hope more boards and manufactures make CircuitPython an option on their products as it provides fast visual feedback and is a simple way to work with microcontroller hardware. I also hope more people start creating libraries for the ecosystem so that future users have an easier time developing new creative things.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
