Hi, just mention that MicroPython introduced a separator option for binascii.hexlify function ...

Neat, thanks!

Note that the DS3231 has an "aging" register that can be used to adjust the TCXO slightly. The register is a signed 8-bit value and controls a capacitor array that is part of the crystal's load capacitance. The DS3231 documentation states that one LSB of the register equals approximately 0.1ppm spee...

The dollar sign at the beginning is one byte, the 'b' the second, followed by four bytes that don't have a corresponding ascii character and are therefore displayed in their \x representation.

Your idea could work. You may find someone has written a VT100 emulator for the Pi, and you can access it from the Pyboard via a UART. You'd need to deal with the VT100 editing commands. Oh ... you are thinking of emulating a full VT100 via UART? With all of the functionality described in termcap? ...

KeyboardInterrupt is a standard Python exception class.

In your case a construct like this should work:

I'm puzzled by the need to recalibrate every few seconds... Isn't the variation primarily due to temperature fluctuations? I'm going to test with longer intervals, but keep in mind that we are talking about an R/C oscillator in an environment of unknown cleanliness. Any amount of flux residue on th...

Not a Mac user, so I can only go by what I find, but ...

That problem looks similar to this one. The bottom line in that case was that the MacOS linker didn't like deep dependency trees. Could that be the same here with the lengthy list of input files?

A different try at answering... It's a messy problem, unfortunately. The industry answer (WPS) is insecure... "Messy" and "expensive". By the time we are done with the AP portion of the setup process we needed a small DHCP server (so the phone or PC gets an IP address), a rudimentary DNS server (to...

These are really two separate questions. How to control the IP address of a device in your own environment? How to create an initial WiFi config (SSID and PassPhrase) in an unknown environment? The answer to 1) can be straight forward. Don't use the DHCP functionality of a consumer grade router. Tur...
