This is great, just did a pip upgrade with no issues.

Hello, I'm new here and I think the project is very good. I have a problem. I used the ESP32 with Micropyton (MP) on a Macbook. (MacOS 12.1 Monterey, ESP32 MP firmware 1.17)
A connection to the ESP32 works.
Firmware installation works.
REPL operation works.
Only file transfer does not work for me.
I don't see the files on the ESP32.
I don't see the files from the computer either.
After being prompted to briefly remove the USB port,
the MU Editor crashes.
PS: Sorry for my English, I'm from Germany.

Hi. I'm following intro tutorial for CircuitPython in Pi Pico, which recommends installing mu-editor. I'm on Debian stable (11). Python is 3.9.2. I cannot install as advertised: https://codewith.mu/en/howto/1.1/install_with_python -- pip3 install mu-editor==1.1.0b7 :

If I use use pip3 install mu-editor, it tries to install 1.0.3, but it fails for mathplotlib:

After sudo apt install libfreetype-dev, mathplotlib seems happy. The next problem is pygame. I wonder if I should abort at this point and just use VS code :-(
I try:

sudo apt install libsdl1.2-dev libsdl-ttf2.0-dev libfreetype6-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libportmidi-dev

. No I end up with

I can install sdl2 dev and pygame 2.1.2; but that last available mu-editor seems to want pygame <2.0

sudo apt install mu-editor. Huh. Can you write that on the damn download page, please? Could have saved me an hour of work. Anyway, thanks for the software.

Dynamic programming languages, huh? Completed installation != it works:

@Sciss MU does not work on Python 3.9 at all at this time. You will need to use at best Python 3.8.

Nicholas Tollervey

@ntoll

(Worth pointing out that the reason it doesn't work is because upstream versions of dependencies don't work with 3.9, rather than Mu itself - we're aware of this.)

Hanns Holger Rutz

@Sciss

I see. I'll have to figure out how to downgrade. 3.9.2 is the standard python of Debian 11

Carl J. Nobile

@cnobile2012

@Sciss Go here to install Python 3.8. https://linuxize.com/post/how-to-install-python-3-8-on-debian-10/
It should be pretty much the same on your Debian 11.

Hi, Just tried to install Mu via Pip (running python 3.10 on windows 10) and received the message "Syntax error: invalid decimal literal" with the caret pointing at the 0b7 section of the command. tried typing in and then copied/pasted directly. currently unable to download and install directly.

Nicholas Tollervey

@ntoll

@misterphil please use Python3.8 and pip3 install mu-editor==1.1.0b7

Hmm.... and you're typing this into your cmd terminal with a virtualenv active..?

misterphil

@misterphil

just installed python and typed straight into the command line - I'll try changing back to 3.8 and having another go. thanks

Carl J. Nobile

@cnobile2012

@rafiqncc You need to use proper formatting in your Python code when you post it here. If not, nobody would know if the problem was actually the formatting.
With that said, this is not really the place to learn Python. This is a forum for the MU editor.

Hi, i use Mu in microbit mode and i try to measure temperature with ds18B20 (one wire protocol). But i fail in finding ds18b20 librairie for microbit. Where can i find py code to drive ds18b20 ?

New Mu Win10 user and the editor will run fine for me as long as the installer launches it. When trying to RE-launch it does nothing, no entries in windows app, system, or security event logs. Windows Defender flags no apps or violations. The mouse pointer indicates activity for maybe half a second, then nothing. I've reinstalled three times and it runs at install completion using the installer check box, but it won't restart using app created file shortcut or the .exe directly. I've searched the Mu install folder but can find no logs or diagnostic data. I'm using adafruit circuit python 7.1.0 with an Adafruit Magtag. Any advice on what my next step is? I searched for any files or info I thought would be relevant but like I said I new to this and this is getting frustrating!

rjlange773

@rjlange773

So can anyone direct me to some support for this app?

Carl J. Nobile

@cnobile2012

@rjlange773 It may be that MU cannot find the environment when you run it. How did you install it? Is it a Python virtual environment?
So this will probably not work unless you are using a virtual environment, but you can try it if you have one.

pip3 install shortcut
shortcut mu-editor

no, I think what it means is a way to isolate your python package installs between projects and use custom versions of the python interpreter

this is a tool for doing such things and its homepage will help you understand a little better

Just installed Mu so I can easily work on some ESP8285 (ESP8266) boards. However while file browsing works fine, the REPL just shows junk, like it isn't set to the correct baud rate. I can't see a way to find what baud rate it uses. If I open the serial port via Putty then REPL is just fine at 115200bps. Am I doing something wrong, or is there a setting that controls the serial port speed somewhere?

I should add that this is on Windows 10, the board I'm using is an ESP8285 module.

Trikkitt

@Trikkitt_twitter

Hmmm, just tried a different module a WeMos D1 mini and that worked fine. So I suspect the issue is something to do with the ESP8285 module and the way the control lines are being driven by Mu. The different bps looks to me like the ESP bootloader, so probably booting in to firmware loading mode or something. Weird that it works fine on Putty but not Mu... :(

Patronsaintofdice

@Patronsaintofd1_twitter

I had a total newb question. I just installed Mu and running it for the first time on an older (2015) MacBook. Everything appears to be working fine, except the minus sign, "-", is a nearly invisible light gray in my editor and the interactive shell. Can someone tell me how to change the font color of this one specific character?

Carl J. Nobile

@cnobile2012

@Patronsaintofd1_twitter I have never heard of a way to change the font color of a specific character on any platform Windoze, Mac, or Linux. However, you can probably change the font itself to one that doesn't have this issue, or maybe just change the pitch (size).

Bohaska

@Bohaska

I'm using Mu to learn Python. How do you install modules that you have installed from the command line? The import command gives a ModuleNotFoundError

Carl J. Nobile

@cnobile2012

@Bohaska It depends on what platform you are on and how MU was installed on that platform. However, in your situation, it seems that you have installed the packages in a different environment than MU was installed. Soooo, we need more info. Mac, Windows, or Linux?

@mycroft47

I have exactly the same problem as @Bohaska. I am an experienced programmer but new to python and mu. The python script I am running has this line which fails:

from pathlib2 import Path

I have run pip3 install pathlib2 in Terminal with no errors. Can someone explain why Mu does not see pathlib2?

2017 MBP running Monterey 12.0.1

mycroft47

@mycroft47

Update. I've tried running my .py script from Terminal and I get the same error: ImportError: No module named pathlib2

However, pip3 install pathlib2 runs in Terminal with no errors.

Nicholas Tollervey

@ntoll

Hi @mycroft47 and @Bohaska - Mu runs its own isolated version of Python (i.e. Mu comes with Python - this means beginner users of Mu don't have to go about installing a bunch of opaque technical stuff.... "It just works" :tm:). To install packages for Mu's version of Python, hit the cog icon on the bottom right and select the "third party packages" tab. Then just make sure the list of packages you need is enumerated in the text area (one package on each line). The whole process is explained here: https://codewith.mu/en/tutorials/1.1/pypi

mycroft47

@mycroft47

@ntoll Thanks a lot. Problem solved. I hadn't even noticed the cog icon!

A note: in the Third Party Packages dialog, it is not immediatly clear that you can enter package names into the empty box.

Nicholas Tollervey

@ntoll

@mycroft47 aha... thanks for the feedback. I'll try to update the copy in the UI to make it clear. Feedback = coding fuel. ;-)

@ntoll

@choredarck how did you install Mu..? If you're on Windows or Mac please use the "official" installers, and let us know how you get on.

@GooseTheCat8602 anything published by adafruit.com (for CircuitPython) is very good.
