Running embassy_hello_world example stand-alone

[lure23]

I noticed that currently (10-Jul-24) the Embassy examples cannot be reproduced outside of the cargo xtask setup. This is down to the publication of the latest code to crates.io.

This boils down to one of two routes:

• If targeting a (single) known chip, see here
• If wanting to target 2 or more chips, see ESP32-Embassy sample - a small repo I made to document the current state and steps I took.

The aim is to:

• be able to work on cargo only (using xtask internally for esp-hal is fine of course!)
• be able to pull reasonably working 😉 versions from crates.io - no file paths needed for dependencies

I am confident this will happen in its due course. In the interim, decided to leave an issue so that:

• others will easily see "what's up"
• there's a place to follow this from the point of outside usage - not merely from within esp-hal

Thank you for opening this issue. We are aware that this currently quite difficult, sorry that you have been having problems. We're planning on publishing a new round of packages next week, and following that our next release cycle will be focused on improving usability. I will be sure to mention this issue during our team's planning meeting next week.

In the meantime, while this is not a true solution, I have made a template for using esp-hal with embassy, which you can find here:
https://github.com/jessebraham/esp-hal-template

It's still quite basic, but at least should generate the boilerplate needed to build an Embassy application without relying on our xtask package. If you have any problems or additional requests, please feel free to open one or more issues on that repository. I threw this together pretty quick yesterday, so there may be some minor issues; I plan to expand on it a bit this weekend.

No worries! The repo you linked to was helpful in seeing which dependencies are really needed.

Glad to be on this ride! Nice to know momentum is there.

Looks fine now, with esp-hal 0.19.0 et.al.
