Adafruit Sponsored Libraries and Drivers on GitHub¶
These are libraries and drivers available in separate GitHub repos. They are designed for use with CircuitPython and may or may not work with MicroPython.
Foundational¶
These libraries provide critical functionality to many of the drivers below. It
is recommended to always have them installed onto the CircuitPython file system in
the lib/
directory. Some drivers may not work without them.
Board-specific Helpers¶
These libraries tie lower-level libraries together to provide an easy, out-of-box experience for specific boards.
Helper Libraries¶
These libraries build on top of the low level APIs to simplify common tasks.
User Interface and GFX Helpers¶
Helpers for building graphical interfaces using the displayio core module.
Motor Helpers¶
Helpers for driving motors, servos, and steppers.
Internet of Things Web Service Helpers¶
Helpers for connecting with hosted and self-hosted internet-of-things web services.
Internet-of-Things/Wireless Protocol Helpers¶
Helpers for interfacing with the internet or wireless communication.
CPython-module Helpers¶
Pure-Python implementations of standard CPython libraries. Some of these modules may have a CircuitPython Core API implementation too.
Audio Helpers¶
Music, noisemakers, and more.
Displays¶
Drivers used to display information. Either pixel or segment based.
Pixel based displays are implemented in two different ways. The original method called “framebuf” uses a traditional frame buffer model where all pixels are stored in the microcontroller’s ram. The newer method called “displayio” generates the pixels on the fly and relies on the display’s ram to store the final pixels. “displayio” drivers will also work with CircuitPython to display error messages and other output to the display when the user code is not using it.
The “displayio” drivers are recommended.
Color TFT-LCD¶
OLED¶
E-Paper / E-Ink¶
Real-time clocks¶
Chips that keep current calendar time with a backup battery. The current date and time is available
through datetime
.
