Re: ESP32 broken filesystem

Usually, this kind of problem arises when the file is open at the time of the power outage. Sofware solution So you can close the file every time you end writing a file. This will limit the risk of filesystem corruption. But don't suppress them of course. Hardware solution You can put a supercap bet...

Re: Documentation for ESP32 Port

There is no documentation for ESP32. Usually the ESP8266 one do the trick.
You only have access to documentation for the pyboard because you are in the "latest" release.
Select "1.9.4", you will then be able to choose between different boards.

Re: DS1307 interfacing with sparkfun's the thing

Hi,
DS1307 is now an integrated circuit "from the past". It works on 5V, if you power it with 3.3V it may not work.
You'd better switch to a DS2321 wich is designed to work from 3.3V supply and is much more accurate.

Re: Advices for "mission-critical" applications

I am not sure MicroPython is qualified for "Mission Critical Applications" and the same remark apply to the underlying code from Espressif.

Re: File write speed

You can store the samples in a FIFO (10 samples deep will be enough) so they will accumulate during the 80ms dead time and when the write buffer is available you can resume the transfer.
