@teastain Nice work.

@aafortinet A mate of mine had the same issue -- seemed not to work until he used it within the 2-150cm parameters. The all good.

Hi @cognitive5525,

Were you thinking more like a M5Stack reference rather than how-do document? I would love that.

Maybe like this
https://docs.m5stack.com/en/uiflow/hardwares/microphone
with further breakdown of each function with syntax and parameters in MicroPython code.

Yes a reference as you'll find for the stock Micropython. Tutorials or Howtos are also find but usually only in the very beginning.

Have you tried using Visual Studio Code to program devices directly? I might try Thonny because I need something that works across macOS, RPi and Linux. VS Code was ideal, and I have been using it, but I couldn't "add device" when I tried on macOS today.

I tried it once or twice with VS some time ago, but I couldn't get the plugin work well. It was difficult to establish a stable connection to the devices.

I had to tweak Thonny though:

@felmue said in M5.shutdown(x) does not last x seconds:

the shutdown functionality only works when M5CoreInk is running from battery.

ah haaaaaaaa! ok! Thanks for the remark! Indeed. And now it works (when from battery).

And if somebody wonders, it might be useful to note in the doc that shutdown() actually has the M5 run again the setup() code (it makes sense, as it is "shut-down" but worth mentioning because it changes the way to implement things).

The distances I get are really strange:

The values are well below or well above the expected ones. For example, for a distance of ~95cm the sensor answers 4.5cm. For a distance of ~110cm, 4.9cm. For ~35cm, 3.7cm etc. The values change for the same distance. So different measures of ~200cm gives 13.7cm or 79.6cm the next time...

The command Wire.begin(32,33) seems correct as I realize those are the ports for the sensor on the CoreInk.

So, what am I doing wrong?

@ajb2k3 sorry, what do you mean by "HV write"?

thanks, this should work out fine :)

@felmue thanks! It works fine after the update :)
