Yes, watchdog timer could be an idea. The same can be done with a normal timer and calling machine.reset() when it fires.
However I was wondering if there was a more graceful way of handling this, e.g. interrupting just the hanging urequests.request() method and then continuing with the program without rebooting the whole device.
The urequests.request() method does not implement e timeout parameter (like its big brother). So if there is not response to a certain request, the method will hang forever.
To work around this I am starting a timer just before the urequests.request() call and stop it directly after it. So if the method does not return within a define time, the timer will fire and I can do something.
So the question is, when the timer fires, which means urequests.request() is stuck, what can I do to recover? One thing could be to reset the device. But is there a more soft way to do this and continue with the application?
Thanks, Ondrej
Thanks a lot. This seems exactly what I was looking for. Command line is not a problem. Will try it.
I accidentally deleted the wav file in the res/ folder on the Core2 flash (don't remember the exact name of the file). But you could just rename it. Now the startup sound is gone. So this is a qick'n'dirty fix if you don't want this sound.
Is it possible to distribute a Micropython application (for Core2 in my case) as binary flash image which can simply be burned on the device with M5Burner?
We would need a way to create that image from a device running the application and having all needed files installed.
Any idea ?
According to this documentation the object returned by M5Screen() has the methods get_new_screen() and load_screen().
These seem to allow switching between multiple screens but I cannot work out how is this supposed to work. Can anyone point me to some example code which shows the correct usage of these functions ?
Thanks a lot.
Thanks. I checked on the Core2 and here battery voltage also ranges from about 3.2V to 4.2V.
I see that your code applies to the M5stickC. Do you think the table is the same for the M5 Core2?
Is there a Python API to get battery charge level for the Core2 battery?
I found power.getChargeState() but it just returns true/false (charging/discharging). There is also power.getBatVoltage() which could be an indication of the charge level but would need some additional math to calculate the percentage.
