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

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 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.

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.
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... :(
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?
@cnobile2012
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
However, pip3 install pathlib2 runs in Terminal with no errors.
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
@GooseTheCat8602 anything published by adafruit.com (for CircuitPython) is very good.
THANKS for Mu! Running Win10, ESP32. Minor Point: When starting Mu, loading a program, clicking RUN: Mu switches to REPL but code does not run. Clicking Run again executes code. Should Mu default to starting with REPL active? I am writing stuff for Education program and looking for any "Minor Confusions" :-) I am good at finding those. Regards, Terry
Hi Everyone, Question about RUN and "Stop".. Running Win10, ESP32. What is the best way to STOP running code?? (D id there used to be a STOP button?)
Present behavior: Code loaded in editor, REPL visible, click RUN. Code runs, REPL shows POWERON_RESET (And other setup lines), then
MPY: soft reboot
raw REPL; CTRL-B to exit
>OK
(THEN DISPLAYS any PRINT from code)
How to STOP??
I click REPL and code stops, and full editor window displayed
I click REPL again and REPL displays, showing the (POWERON_RESET ... down to >>> prompt)
@TerryKing :wave: We love getting feedback and reports of problems. The "run" button behaviour you first describe is not correct. What version of Mu are you using..?
(not correct = "that's not how it's supposed to work")
Hello Nicholas, First: many Thanks for your dedication to mu-editor! I can promise you that 100+ kids in Vermont USA will learn a lot using your work.
I am running WIN10 and mu-editor 1.1.0b7 This is ESP MicroPython Mode. Python3 Mode works great. Kids will start there.
I'd be happy to do anything I can to help now or in the future. I'm an Engineer who went Rogue at IBM and wrote code when that "Wasn't Done". I have quite a bit of Arduino and ESP32 experience and helpers who know more...
Let me know what I can do to help. Regards, Terry

@TerryKing: we limited our builds to 64-bit a couple of releases ago basically as a pragmatic measure. Since we ship the installers with quite a few wheels and so on, plus a static Python image, it became quite a burden. And we took the view that, by this time, even older school kit was likely to be 64-bit. It shouldn't be too difficult to build a 32-bit installer if this was an obstacle for you... assuming we can get matching wheels from the underlying libraries
@tjguk:matrix.org : Thanks for the clear reply. Hmm.. I am working with a program that will have about 150 elementary-middle school kids with no coding experience, learning Python in an online environment : example:( https://hourofpython.trinket.io/a-visual-introduction-to-python#/welcome/an-hour-of-code) That's great to start.. But I am working on a project that bridges those kids AFTER they really learn some Python, to Python3 and MicroPython(esp32) using mu. And that trinket thing charges $3 per seat per month for Python3 and Pygame etc. OpenSourceRules!
I will try to get the first-phase of online students to tell us what their home computer hardware is. Hmm is there a good online app that will do that for an online user?? So I hope to have a better perspective on the need to a 32-bit installer. Not QuickCritical.
Thanks and let me know what you think...
OK. but the HowTo for mu says: (https://codewith.mu/en/howto/1.1/use_portamu)
--(copy)--
"Sometimes it’s not possible to install Mu because the computers you have available are locked down by somebody else.
Perhaps you find yourself running a workshop in a library or your school’s network administrator is more likely to say “get off my lawn” than “let me help you with that”. Don’t worry, thanks to the remarkable work of 14 year old Josh Lowe, you can run Mu from a pendrive (those dongle-thingamabobs for storing files that you plug into the computer’s USB port). This technique should work on both Windows and OSX.
--(end)--
If this is really obsolete maybe it should be removed, or labelled How NOT :-)

I need help. I am trying to create a class that can calculate the area, volume, and perimeter of a 3D object. The problem is, that I do not know how to make a class with multiple constructors, if that's possible. All help is appreciated.
import math
class Object:
def __init__(self, x, y, z):
self.x = x
self.y = y
self.z =z
Volume = x * y * z
print(Volume)
def area(self):
Area = self.x * self.z
print(area)
eObject = Object
