Async API? #1

Open tazz4843 opened 1 year ago

Would be great to see an async API wrapper option here. For some context on my use case: I'm looking to set up a weather station using this sensor. My main board is a Raspberry Pi Pico W, which requires special setup for the WiFi chip, and I'm using embassy for this, which is a fully async runtime.

Hello @tazz4843, I'm not opposed to this but I have to admit that I did not have worked with embassy so far. Could you sketch out how an async API for this sensor should look like? Or do you have a good example of such an async API you could point me to?

Is diy-weather-station the project in question?

embassy implements embedded-hal-async traits for all its HALs so such an API could match the sync API 1:1, just with an async implementation of the I2C bus instead. I haven't dug much into the code, but I doubt it would be difficult for me to make a PR if that's something you'd want.

Yes, that's the project in question, however most of the code is only locally on my computer and hasn't been updated on GitHub in a while.
