General question: can frozen bytecode speed up code execution or is it more about saving storage space?

An update regarding our project: We are developing our solution in a best-effort way because the project is being funded solely by us – company founders. There will be approx. 3 month interruption in the controller development because we are currently earning money by developing custom IoT embedded ...

Thanks, I already coded my own solution based on bytearray() and append(). Will check those provided by you so I can use them next time

Is it implemented? It seems that the conversion (on WiPy) is done with 'little' as default and sys.byteorder returns the same. Is there any way how to set system byteorder?

Could you please share some performance figures/numbers? Did you somehow manage to speed up Python execution?

Could you please post logic analyzer trace of your optimized solution? Is the HSPI driver designated to be used only with ESP8266 or could it be used with other HW paltforms? I am having trouble with sending 2-byte payload with CS toggle fast enough in my laser 3D printer controller project currentl...

Thank you, I will take a look at that thread.

Is it possible to import MP module written in C from a file stored in the file system (Flash memory or SD-card) ?

Thanks a lot for your answers and opinions. I now understand that DMA will not help in my case. Entire problem is a little bit more difficult, because it is not just about calling machine.SPI.write() on a large list of data and switching CS pin in between each two bytes. I need to do this sequential...

Could I avoid the heap fragmentation becoming worse by simply storing operational data of my embedded device as object attributes initialized during boot process?

Not sure if this is discussed in some other thread, but does anybody have experience with long-running applications built on top of MicroPython? Has anybody tried to keep some MicroPython host running for months or even more than year? The point is - is MicroPython suitable platform for developing e...
