How about on a Core2, and pretty experienced with CircuitPython, which is close.

When will we see an updated version of Micropython for the M5Stack? The current version (1.12) is almost two years out of date.
While the very latest (1.15) doesn't support LAN on the ESP32 (WTF?), 1.14 does, and the newest version of that was released this past March.
RTC (Without battery backup)
In hunting down other issues, I came across several statements that the M5STACK Fire doesn't have a Real Time Clock (RTC). However, if I set the RTC with machine.RTC().dateTime(<Time tuple>), it seems to work. If I think read back with machine.RTC().dateTime(), it seems to be keeping time just fine.
So is the issue that there isn't a battery-backup, and I'll have to set it each time I wake (which is just fine), or that the software for the RTC really doesn't work?
Running out of file descriptors
I'm getting a wierd error when I try to rerun my program:
I am loading
<MQTTClient object at 3fff0720>
Setting the date/RTC
Running off the end
[0;31mE (658885) vfs_fat: open: no free file descriptors[0m
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 2] ENOENT
a ^D soft reset seems to fix it, but...
The dreaded "T" of death...
I'm working on a Micropython program to log MQTT results, and it needs the current time to do so.
I'm working in uPyCraft, with the typical write-download-run cycle, and eventually I get to the point where all my program appears to do is print a 'T', and then hang. I can ^C out of the program, and get back to the >>> prompt, and try running the program again, but the only thing that seems to clear the problem is to power-cycle the M5Stack Fire.
Any idea what's happening?
Source for counter example in video?
I'd like to use the M5stick to make a stopwatch for us old folks that can't see a regular analog one. (I need it for curling, where I can't wear my glasses.)
There is a great video on the examples page of a counter that looks like colored dot matrix, where the colors change with the digit value.
Does anyone know where I can find the source code for that? I've searched the github and I'm not seeing it.
