I have two uasyncio coroutines awaiting the same event . One coroutine is a slow file write, the other one is a fast LCD screen refresh. When the event is set (triggered), is it possible that the slow file write will withhold the LCD screen from refreshing quickly? Do I need to encapsulate the ordin...

Peter's article link appears dead over here.
Nonetheless, I found a copy of this 2014 scroll in a cave on the web…

@stijn No luck here. The 15 minute background loop could in worst circumstances require up to one minute to complete its task.

@Peter Right! I guess, I was still a bit confused since my unsuccessful attempt to install uasyncio on a Pycom flavoured ESP32. That too, may eventually get resolved when Pycom pulls in robert-hh's pull requests. Anyhow, I somewhat lost my interest in Pycom. On the other hand, what a Great Schism we...

However if your application can sleep for extended periods you could design it so that the scheduler stops (run_until_complete), the unit goes to sleep, with wakeup restarting the scheduler. That would indeed be a more clever solution. It is still very tricky, though. Having the Pyboard lingering i...

Here is a simple question:
When calling an await uasyncio.sleep(), does this put the MCU in idle?

Putting an explicit machine.idle() right above an await uasyncio.sleep() line will result in the latter never to be executed. So, that is not a solution to save some power.

Hi lads, I am planning on writing a graphical user interface with 3-button control for the ESP32-based M5Stack . At the same time, two background processes will have to run at 3 and 15 minute intervals. The GUI and background processes should not mutually block one another. However, they do need to ...

There is one caveat with pickle , though. Quoting from the documentation : The Python funcitons eval and exec invoke the compiler at runtime, which requires significant amounts of RAM. Note that the pickle library from micropython-lib employs exec . It may be more RAM efficient to use the ujson libr...

For exactly that reason, I am using a firmware build directly from loboris’s github repository :- … BTW: You can use USB and simply disable their wifi/cloud module in boot.py. Loboris certainly looks to be the cool kid in town! 8-) I will try this out. As a matter of fact, I opened a bug report aga...

Note to myself: Here is the GitHub repository of M5Stack's MicroPython firmware . However, I am extremely uncomfortable with sending my code or WiFi password to some (Asian?) cloud server. Certain details of my code projects are strictly private. Is there a way to still use M5Stack's MicroPython fir...
