Language Flashcards on the MagTag
This project moves your flashcard cram deck to the MagTag with a CircuitPython language learning app. This tutorial walks through two flashcard examples, starting with a simple one to go over the basics of the MagTag library, json parsing, and the new PCF fonts, and a second more complicated example that includes a menu system and repeated study for forgotten cards.
Blinking an LED with the Zephyr RTOS
Sometimes, platforms like Arduino or CircuitPython just aren't enough for a high-performance project. This tutorial walks through the setup of Zephyr, an open-source Real Time Operating System (RTOS) backed by the Linux foundation. An RTOS is like a very tiny version of the OS that runs on your desktop or laptop computer, built for tiny embedded chips that need to do intense signal processing or run many processes at once. In this example, you'll be using Zephyr's built-in setup and build tools to create a basic application that blinks an LED on the STM32 Feather Express board from Adafruit.
Adafruit STM32F405 Feather Express
ST takes flight in this fantastic Feather board. The new STM32F405 Feather that we designed runs CircuitPython at a blistering 168MHz – our fastest CircuitPython board ever! We put a STEMMA QT / Qwiic port on the end, so you can really easily plug and play I2C sensors.
