Read Program back from Core?

sirtet

I have a StickC Plus with a working program on it, but i lost the source file.
Is there a way to read a blockly/python script from a Core device?

I assume the python source code is on the Core Device and being run through a MicroPython interpreter.
Is that correct, or is the Soruce being compiled down to something else before it is downloaded to the Core?
Assuming 1. is correct, is there a way to read back the python script?
(appart from reading it back directly from the flash chip with a programmer and extracting from there)

Yes, the code is in the Core's /flash/main.py, and can be read directly using the UiFlow2.0 terminal.

@sirtet You can also use Thonny

Thanks.

@kuriko, i did not get UiFlow2 to work yet on my StickCPlus (With Firmware 1.13.8). Trying the UiFlow2 Firmware, i only get a blank screen.
But i see i can connect to my Stick in UIFlow1.0 too.
I get to the REPL interface, with os.getcwd() i can see that i am in /flash.
Yes. main.py is what i was looking for.
But i have some questions:
If i use the APPList from the boot menu, some .py scripts are listed, temp, main, test and MyCustomCode.py
in /flash, there is main and temp.
Then, there's a DIR named apps. In it, there's again main.py and MyCustomCode.py.
What's the logic here, how did all the scripts end up where they are?
I guess the "current" one is always copied to main.py, but what's with temp.py and test.py? I am not aware of ever using these names.
Maybe there's a help doc. on the topic that i should read?

@Cognitive5525, with Thonny, i don't see how to get to the file i need. I guess i would need to connect to my Stick first, but don't see anything about it in the menus...

@sirtet Are you using the correct Stick C UIFlow firmware?
There are 3 different StickC revisions. the blank screen suggest that you have the wrong version loaded.
