sonar sensor problem(hcsr04) - time_pulse_us

[crouse12]

The following code for hcsr04 can work on microibit v1, but it cannot work on microbit v2.
Python editor version for my test is 2.1.0-beta.7.
I think time_pulse_us or sleep_us has some bugs.

What's the result you get in a v1 vs v2?

[crouse12]

microbit v1 show distance on led screen.
However, microbit v2 does not show anything.
I found that makecode has the same issue.

I find v0.2.23 of codal-microbit-v2 now released.
It solves pulse problem.
Does micropython update, too?

Yes MicroPython is now updated to codal v0.2.23.

@crouse12 could you please test with the build from https://github.com/microbit-foundation/micropython-microbit-v2/actions/runs/419939816 (this is an automatically built version from a commit on master, so isn't exactly what the next release will look like, but does have the updated CODAL).

[crouse12]

I test time_pulse_us on microbit v2 using the following two MicroPython Versions.
However, they cannot work.
I think there are something wrong on time_pulse_us.

@dpgeorge does the patch from @xmeow look okay to you? Would be great to close this off with the next release if so?
