I was watching a video about running a program in the background by appending the command with & but more importantly that 2 programs could be run simultaneously and it got me to thinking about a project I'm working on that has a repetitive data stream running but needs to respond to changes from a ...

I had another type of board (not running Micropython) that did data logging and what I did was monitor the voltage prior to the voltage regulator (battery or raw voltage) using a voltage divider and when it started to fall below a preset value then immediately close the sd file. That gave me a great...

The code (i.e. .py) lives on flash. It gets compiled into bytecode that lives in RAM (in the MicroPython heap). The entire MicroPython heap is completely zeroed out on soft reset.

Go it. Thanks for the explanation.

So after thinking more about my question I think I'm wrong about where I thought that object or module resides. I would imagine when you type "import <whatever> in the repl that it actually resides in ram rather than flash and that it does get cleaned up when doing a control d correct?

Let's say I have several files in flash directory such as boot.py, main.py, foo.py, faz.py, etc.that are running and are all part of and used in my project code. And then I press control c to stop the program and then with the terminal I see the repl chevrons. So next I want to experiment and let's ...

Just thought of a question... should I have erased flash before I flashed the updated firmware?

Success! Thanks again @jimmo!

Thanks. I've downloaded the latest build and am now waiting for the rest of the required utilities to download so I can update with pydfu on my Mac. I'll let you know how it goes.

New to MicroPython and my PyBoard V1.1. I've gotten most of my programs to work fine and now wanted to implement uasyncio so that I can try and keep part on my program "running in the background" if you will. So I went on the adventure of trying to see if my setup has uasyncio by trying the suggesti...

Thank you I'll give it a try.
