Examples of Embedded Swift code for nRF52xxx micro-controllers

This repository contains examples of Embedded Swift code exercising the different features of development boards based on nRF52xxx microcontrollers.

LED

The LED folder contains a Swift struct that abstracts away all the C calls to Zephyr and presents a natural interface to control an LED connected to a GPIO pin.
It is initially based on the nrfx-blink-sdk example provided by Apple.

Check out the Controlling a LED using Embedded Swift on nRF52 blog post to follow along as we build from this sample code.

Button

To add interactivity, we'll now look at using a button.
Look at the README.md file inside the Button folder for more information.

Button and LED

We build on the previous 2 projects and create a button that toggles the LED on and off when pressed.
Check out the Creating a Swift type for button input on nRF52 - Part 1 and Creating a Swift type for button input on nRF52 - Part 2 blog posts for more information.

Random

In this project, we show how to generate random numbers using Embedded Swift and nRF Connect SDK.
Check out the Randomness on nRF52 using Embedded Swift blog post for more information.

Timer

In this project, we implement a Timer to schedule code for later execution, with optional repetition.
Check out the Timers in Swift on nRF52 blog post for explanations on the code present in this project.

Traffic Light

This example implements a simple traffic light, with some basic timing logic to move between the different states.
