Yes and I have it running a very simple script that flashes the LED and prints 'Hello, CircuitPython!' to the console (presumably).

I assume there's no boot.py ?

atomic mural Nov 14, 2021, 5:10 AM

#

No. Right now it's connected as CIRCUITPY

#

I don't know if it's useful, but Mu doesn't see an attached device when I click the 'Serial' button.

beta 6 ?

atomic mural Nov 14, 2021, 5:13 AM

#

I don't know. This is all very new to me.

#

CircuitPython version is 7.0.0

crimson spire Nov 14, 2021, 5:14 AM

#

it should be in the Mu window title I think, or at the top of the log when you click on the wheel at the bottom right

#

or cog actually

atomic mural Nov 14, 2021, 5:16 AM

#

1.03

#

I'm on Ubuntu and installed it via snap

crimson spire Nov 14, 2021, 5:17 AM

#

ah you should update to 1.1.0-beta-6 to begin with

#

something like pip3 install mu-editor==1.1.0b6

#

It's extremely laggy to the point of being unusable, so I've been using SublimeText.

I'm not the right person for linux minutia though, it's beyond my knowledge, what I know is that there might be permission issues on linux, but I don't know if it's relevant: https://learn.adafruit.com/welcome-to-circuitpython/kattni-connecting-to-the-serial-console#serial-console-issues-or-delays-on-linux-3105120-9

I've been trying to access the serial console via the default Linux console, but the serial port doesn't seem to show on the list.

#

I don't believe I can address potential permission issues until I know the serial port.

#

I will look into updating Mu and see if that resolves anything.

#

there is something about the dialup group

atomic mural Nov 14, 2021, 5:23 AM

#

Oh, yes, the dialout group. I did that and rebooted.

crimson spire Nov 14, 2021, 5:24 AM

#

Mu starting with 1.1.0 beta 5 has a module that will identify the port automatically but looking for the serial ports names, so if it's on something else than ttyACM0 for some reason it should find it, but beyond that I don't know

atomic mural Nov 14, 2021, 5:25 AM

#

I will see if I can get Mu functioning properly.
I appreciate the help.

atomic mural Nov 14, 2021, 5:43 AM

#

I tested the Feather with Mu on Raspbian on a Raspberry Pi. It found and connected to the serial console without a problem.

Yay!

#

also try checking dmesg output after plugging in the feather

atomic mural Nov 15, 2021, 3:49 PM

#

@stray igloo What should I be looking for in the dmesg output?
It looks like it recognizes the Feather M4 Express as a USB device (as well as the keyboard and mouse).

stray igloo Nov 15, 2021, 4:10 PM

#

it'll mention where it sets up the /dev entry

atomic mural Nov 15, 2021, 11:03 PM

#

There is no mention of /dev in relation to USB devices.
