Micropython code freezing.

[Mickey Mx]

Aivar,

Are there any Thonny plug-in tools that facilitate code-freezing?

I'm not sure that this is something that Thonny could do.

Frozen MicroPython code is code that is part of the firmware, i.e. it is part of the MicroPython binary that you flash to your board, not something that you add afterwards (which is where Thonny comes in).

Did you have a specific requirement in mind here?

Hi Andy,

I have an micropython application running on an ESP8266; the unit is normally in deep-sleep. When awakened by an external event, it makes several imports, then executes the event-handler. I've noticed a delay in the execution of the event-handler that can be attributed to the imports. Freezing the code would eliminate the excessive delay by including all code in firmware.

It may reduce the delay slightly, I guess.

In order to freeze your imported modules, you’ll need to rebuild MicroPython itself, and re flash your ESP8266. Thonny doesn’t execute full rebuilds of MicroPython, you’ll need to do that yourself from a command line build environment.

Thanks Andy, From what I've heard from others on the topic; freezing can significantly improve response time due to imports when you're constantly re-booting as my application does.

BTW: It might be really useful to consider whether Thonny could incorporate the tools necessary for a micropython rebuild and re-flashing, as it does with the esptool; then Thonny would be a true IDE.
