HackSpace Magazine Issue 31: Drawing graphs with CircuitPython #CircuitPython #CLUE @HackSpaceMag @ben_everard

The new HackSpace Magazine Issue 31 presents Drawing graphs with CircuitPython:

We looked at using the displayio (library) to drive graphics on CircuitPython back in issue 22. However, in the past year, the library has seen a lot of development – so let’s take another look at how to draw graphics with this microcontroller. Back then, we looked at drawing bitmap graphics on the screen, so now let’s take a look at what it’s like drawing with primitives like triangles.

We’re going to take a look at a simple gauge that displays data a bit like a car speedometer. We’ve created a library to make this easy – so the basic
way of using it is just to copy the gauge.py file from hsmag.cc/1fH3ZZ to the lib folder of your CircuitPython device. You’ll need a screen to make this work. We’ve tested this out on both an Adafruit CLUE and a Pimoroni Enviro+ FeatherWing. The code we’ll look at here takes the  accelerometer data from an Adafruit CLUE and displays it as gauges.
