Modify imports for v2-speaker example #145

Closed a-camarillo closed 2 months ago

a-camarillo commented 2 months ago

When building the v2-speaker example I am receiving both a warning and error related to OutputPin.

On line 43 I am receiving the error: no method named 'set_low' found for struct 'P0_00' in the current scope, as well as, an unused import for

 use embedded_hal::digital::OutputPin;

I was able to fix this error by removing the embedded_hal import and replacing it with:

use microbit::hal::prelude::OutputPin;

if this is indeed an error in the example code I'm happy to open up a PR for the change.

BartMassey commented 2 months ago

Would it be possible to paste a before-and-after of Cargo.lock? Would be nice to know what versions are involved here.

Here is the Cargo.lock with use embedded_hal::digital::OutputPin; and the build failing.

edit: after looking through the above I don't notice any difference in version numbers, I might have misunderstood the before-and-after part of your request

BartMassey commented 2 months ago

Yeah, you'll need to delete Cargo.lock before each build, as it's cumulative.

You can see that Cargo.lock currently contains both embedded_hal 0.2.7 and embedded_hal 1.0.0. This is what I was wondering about: with both versions in there things may go awry.

I'll try to poke at this myself sometime soon: want to make sure everything works in the new world and in the old one.

How are you building the example, and on what git revision? On the latest main branch, if I run cargo build --features=v2 --target=thumbv7em-none-eabihf in examples/v2-speaker it builds fine.

a-camarillo commented 2 months ago

I came from the Rust Embedded Discovery Book which uses version 0.12.0 throughout their book and proceeded to work on examples with that version. After removing the Cargo.lock file and bumping the microbit-v2 version to 0.14.0 the build runs fine.

Looking at the history for 0.12.0, examples/v2-speaker was still using use microbit::hal::prelude::OutputPin;. I'm guessing that as of the Update to latest HAL crates, the issue I was running into was fixed.

My apologies, that's my bad as I should have looked more at which version I was using to build.
