@ajb2k3 When might we expect version 2.0?

Conrad

I would like to try the examples, but I don't know how to external use/import the modules/libraries like matrix.py. I've looked in most places but I can't find anything documented anywhere. I'm using UI Flow desktop v1.4.5. If you could point me in the direction of how I can use external modules/libraries with UI Flow desktop or what other IDE would be better I would much appreciate it, thanks.

@m5stack UiFlow Version 1.4.5 (Desktop) Issues

Pressing </> Python:

At any time wipes out any code you have in the edit window, why?

Cannot save code, also two methods available to save:

Or
0_1586899862312_ae0ea337-c3c8-4c38-812b-817cba96a19a-image.png

Using either method saves a main.m5f file (Note, not a main.py), opening the main.m5f results in:

rom m5stack import *
from m5ui import *
from uiflow import *

rgb.set_screen([0,0,0,0,0xFFFFFF,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0])
setScreenColor(0x222222)

Ok, so I thought I would change version via the Ver button at the top of the screen, now all I get is:

0_1586900318444_c38ae718-927a-486d-b540-bc31fbbfe7f9-image.png

On startup I get:

0_1586900382795_704ee601-390a-4461-89be-2cde53e65372-image.png

Everytime even though the driver is installed. I select Skip which takes me to the main GUI which informs me the Atom-matrix is detected.

Basic editing navigation via shortcut keys such as <ctrl> S don't work - very annoying.

Because of the Javascript error I can't open in UIFlow anymore to continue.... Now I'm stuck.

Please tell me I'm doing something wrong and being a complete idiot...

Thanks.

@robalstona Thanks for posting, I might give this a try!

Thought people might be interested in a simple working example of an Access Point web server on the ATOM Matrix:
(Wasn't sure if this was the correct place to post ...)

Based on:
https://randomnerdtutorials.com/esp32-esp8266-micropython-web-server/
http://community.m5stack.com/topic/1262/m5stack-basic-grey-as-wifi-ap

Known Issues/Bugs:
Very flaky - crashes lots .. Seeing micropython REPL error:
File "<string>", line 77, in <module>
OSError: [Errno 104] ECONNRESET
Atom dies.... Needs hard reset.

Not sure why only momentary display Green/Red, looks like constant socket accepts..
Need to investigate the unused addr return from socket accept, is this useful?
Response Initial state affected by loaded page in browser?

Anyway, all constructive comments welcome.

One for m5stack: UIFlow-Desktop V1.4.5 is awful, can't even save my micropython code, please, please fix/update.

How do I get the listing to display as code like in other posts? DONE - see below!
