⚙️ I've just merged a big change to the PlaydateKit build system. It now uses the SwiftPM build system for almost all of the build as opposed to a bunch of fragile individual commands and flags. This means:
- 1.5x faster clean builds
- 9x faster incremental builds
- Much more stable linux builds
- Possibly Windows support soon?

The embedded Swift team has been making tons of improvements, it's easier than ever to get started with #EmbeddedSwift on #Playdate!

In this week's #ExploringUncut, @twostraws new open-source project ShipShape, SwiftCraft conference, #EmbeddedSwift documentation and loads of tech announcements...

I'd like something to keep tempo with while playing guitar, so let's design a drum sequencer using #EmbeddedSwift and the very limited set of parts I have laying around.

No #ExploringUncut this week but a longer post on #swiftly and its impact on my #EmbeddedSwift development environment

Oh neat, I guess at some point I upgraded my CMake install to 4.0 which I guess drops compatibility with CMake 3.5 which the 1.5 branch of the RP2040 SDK uses. I can't update to the 2.0 branch because of some incompatibility when building Swift 😖

#EmbeddedSwift

@twostraws @mikaelacaron @swiftovercoffee
A lot of #EmbeddedSwift: https://github.com/nelcea/EmbeddedSwift-nRF52-Examples https://github.com/nelcea/EmbeddedSwift-nRF52-Swatak https://github.com/nelcea/EmbeddedSwift-nRF52-ArcReactor
that I try to share with community whenever/wherever I can: https://github.com/ebariaux/slides

Ultimate project though is use Swift everywhere: firmware with EmbeddedSwift, mobile app using SwiftUI, backend using Vapor and some WebAssembly for the more advanced parts of the web UI. It's been on-hold for nearly a year now: https://github.com/nelcea/PAL

Last week I skipped #ExploringUncut, I just did not have the energy to write.
Back this week with a new edition of Embedded Swift community hour, my first time attending #iOSDevHappyHour and some BLE in #EmbeddedSwift examples.

In this week’s “Exploring Uncut” (https://www.ericbariaux.com/posts/exploring-uncut-20250324/), I fix my issue with connecting a Seeed Studio Round Display to a nRF 52840 dk board and progress with an #EmbeddedSwift implementation of Gyrus.

Also some answers in the value type, reference type, stack and heap quest, another Paul Hudson stream and a new Embedded Swift Community Hour coming up next Friday.

So it seems like the same symbols are being produced by both my test library and test executable. I kind of figured that's what whole module optimization was for. Or maybe I need to find the right command for the linker?

#EmbeddedSwift

Also, as cool as I think it would be to figure this all out on my own, if someone else has already done it please tell me.

On the other hand maybe I get a good conference talk about of the project. "So at first I was confused, and then I swore at the compiler for a while, and then it worked!”

#EmbeddedSwift

Exciting progress? on building my RP2040 test project with Swift. I think I got the right toolchain installed because now instead of “No such file" errors I'm getting so many duplicate symbol errors the compiler gave up! No idea where to go from here

#EmbeddedSwift

All of the parts for my button project finally came together. I redesigned the enclosure to make the PCB and button easier to install and added an ARRI anti-twist mounting system to the bottom.
I also borrowed a little bushing press and printed a jig to add the threaded inserts.

If you’re interested in #EmbeddedSwift, come say hi during the first Embedded Swift Community Hour.

[Embedded Swift Community Hour! - Development / Embedded - Swift Forums](https://forums.swift.org/t/embedded-swift-community-hour/78406)
Thanks to @rauhul and @kubamracek for organising this.

Still working on the specifics, but I think something like this might work well. It makes it easy to show controls and information for a device that all updates automatically from the store of known devices and separates out a default state for when the device is disconnected.

`DeviceView` is generic soup, but there might be a way to clean some of that up

#SwiftUI #EmbeddedSwift

Did some reorganization and put the shared models in their own target that can be conveniently referenced via SPM on the client side and, less conveniently, from the CMakeLists file for building the Pico binary. But at least if I make changes I'm no longer copying and pasting for each platform.

Would still love some kind of SPM support for building embedded binaries, but even this is a nice step forward

#EmbeddedSwift

I’m fairly pleased with this. All of the features are controlled from the UI, which matches the data sent back from the Pico. Now to find a use for it

#EmbeddedSwift #SwiftLang #3DPrinting

Not gonna lie, I’m shocked this is working correctly, and it didn't even take that many attempts

#EmbeddedSwift

More progress! Got USB communication up and running and can get button input and set the LED output.

I think next up is going to be merging the embedded code and client code with conditionals so they share files. I don't think that was an option the last time I tried embedded Swift

#SwiftLang #EmbeddedSwift

Took a break to make dinner & watch some Star Trek and realized I'd made some silly mistakes in how I was setting up the button IRQ. The callback is working now, just need to add some debouncing logic

Trying to run Swift on RP2040 again. It's going 🫤
