How about digital sound sensor?

I found this page form ST. It seems as they support their own PDM microphones with their lower ST embedded systems. MP34DT01is a MEMS digital out audio sensor . PDM is a 3 Mbit/sec serial bus for audio. So I think it might be possible to support them om Micropython too. I know that there is already ...

The RTC can wake it up (but this feature is not yet implemented in software, it will be soon)." This email was from end of october. So I hope that once my...

Re: setting frequency??

Thank you very much for the explanation.

Yes; I prefer getting "bugfixes" over "delivered with actual firmware version".

As the product is new, I would need to reflash the board anyway sometime in the future.

increase precission?

Can I do anything to increase the precission of the ADC? What is used as voltage reference? I want to measure weight and do use an analog amplifier to amplify the resistor bridge I am not sure how stable the internal reference is. Reading out VREF did not deliver a stable value (it was only just mos...

VBAT usage?

If I run a battery powered installation, I can connect the power to VIN.

But what is VBAT for then?

Re: Micro Python development wish list

Verifiable environment. I think Micropython does have a great future as a minimalistic "operatingsystemless device" for absolut secure devices. (think about it as a signing or encrypting device, or digital key, or Bitcoin storage) To be a secure device, the vectors of attac in a device should be min...

Re: setting frequency??

As I ordered end Of december, I had hoped that I get a current Firmware version.

Sending out outdated firmware version to force people to do a firmware update seems to me
a little bit "odd".
