Right now it is a refactor of a simpler version that you can find on the hotfix branch that I use to run the fans right now but it has its flaws too hence the refactor that now has a deadlock 😂

The core and code running on the pico is in the fan-controller crate/subdirectory I linked.
My other worry is that I am simply doing too much for the limited hardware and it is ultimately something like running out of memory.

It has definitely grown beyond a simple project so I can fully understand if it more than you expected and don't have the time for it. It is also why I have procrastinated doing the work of trying to narrow it down beyond the logs I added.

and through modbus it controls two fans. There are two LEDs that I control to display the state. I don't have the wiring documented but I should at some point so if you are interested I can do it.
There is also a whole MQTT part through which I make it controllable through Home Assistant.

How do you find deadlocks in your embedded code? The pi pico I programmed with embassy rust doesn’t react after the first input I trigger and I don’t know how to debug it.
Probably gonna need to turn parts of the code off to narrow it down but that sounds like a hassle. Maybe it’s not a deadlock

Oh the 1PW extension has some weird edges 😂
I implemented passkeys recently and it was the only extension that would sometimes add base64 padding to values or break the built-in json encoding for the credentials API

Although not sure if that button can then close the dialog and submit the form at the same time. But that is less important since the submit often triggers some form of navigation.

It would be nice if inside a form they could be triggered by the enter key just like submitting. I sometimes need to open an “are you sure?” type of dialog before submitting a form and putting the actual submit button inside the dialog already works with the button form attribute.

What is the differentiation to data attributes?

Oh this is cool, would this enhance the use of data attributes even more?

Prf and large blob would allow this but so far that only really worked in safari with apple keychain for me. But this is maybe on the Authenticators and not the browsers 🤷

Another one I really want is better support for encryption at rest in browsers and end to end encryption scenarios. Basically getting a key that can only be accessed by your page and is stored on the devices secure key storage would help.
The only way to do that are Passkey extensions right now 1/2

Why is base64(url) to UInt8Array conversion still so hard?
There is a new API I believe but support is lacking
