This repository is a set of demonstration projects of Embedded Swift. Embedded Swift is a compilation and language mode that enables development of baremetal, embedded and standalone software in Swift. To learn more, see:
- Blog post introducing this repository
- Swift forums thread about this repository
- Discussions about Embedded Swift on the Swift forums
- Embedded Swift Vision Document
- Documentation for Embedded Swift
Warning
Embedded Swift is experimental. Some information on this page might be out of date with latest development.
Important
Use the latest downloadable 'main' Development Snapshot from swift.org to use Embedded Swift. Public releases of Swift do not yet support Embedded Swift.
Note
This repository contains code that is not continuously developed, instead it's presented "as is" for educational and demonstrational purposes. Making major improvements to existing examples is discouraged, but additions of new examples is welcome.
| Name | Platform | Description | Photo |
|---|---|---|---|
| stm32-blink | STM32F746G-DISCO | Baremetal program that blinks an LED repeatedly. Does not use any vendor SDKs or external toolchains. |  |
| stm32-lcd-logo | STM32F746G-DISCO | Sets up layers on the built-in LCD and animates them in a loop. Does not use any vendor SDKs or external toolchains. |  |
| stm32-neopixel | STM32F746G-DISCO | Uses SPI to program a NeoPixel LED strip. Does not use any vendor SDKs or external toolchains. |  |
| stm32-uart-echo | STM32F746G-DISCO | Uses UART to implement a simple "echo" firmware. Does not use any vendor SDKs or external toolchains. |  |
| pico-blink | Raspberry Pi Pico | Baremetal program that blinks an LED repeatedly. Does not use any vendor SDKs or external toolchains. |  |
| pico-blink-sdk | Raspberry Pi Pico | Baremetal program that blinks an LED repeatedly. Demonstrates how to use code and libraries from the Pico SDK and add Swift code on top of it. |  |
| pico-w-blink-sdk | Raspberry Pi Pico W | Baremetal program that blinks an LED to signal 'SOS' in Morse code. Demonstrates how to use code and libraries from the Pico SDK and add Swift code on top of it. |  |
| nrfx-blink-sdk | nRF52840-DK | Baremetal program that blinks an LED repeatedly. Demonstrates how to use code and libraries from the Zephyr SDK and add Swift code on top of it. |  |
| esp32-led-strip-sdk | ESP32-C6-DevKitC-1 | Demonstrates how to integrate with ESP-IDF SDK and use Swift to control the LED strip library from the SDK. |  |
Note that the SDK integration examples (Pico SDK, Zephyr SDK, etc.) are not recommendations or endorsement, the same is true for build system choice (Make, CMake, SwiftPM, shell scripts). Embedded Swift aims to be versatile and to allow for integration into more existing SDKs and build systems, and the example projects are merely showing the possibilities.
| Name | Platform | Description |
|---|---|---|
| swift-matter-examples | ESP32 | An Embedded Swift Matter application running on ESP32-C6. |
| swift-flipperzero-hello | Flipper Zero | A demonstration of running Swift apps on the Flipper Zero. |
| PlaydateKit | Playdate | A full featured framework for building Playdate games using Embedded Swift. |
| swift-playdate-examples | Playdate | An Embedded Swift game running on Playdate by Panic. |
| swift-for-wasm-examples | Web | A "Swift Audio Workstation" example built with Swift for WebAssembly running in the browser using Embedded Swift. |
