Traceback on AtomMatrix when running example

[mb]

Hi all,

I am a newbie to M5Stack, just got my AtomMatrix and a few other goodies.

I followed the instructions
https://docs.m5stack.com/#/en/quick_start/atom/atom_quick_start_uiflow

And ran the example code
https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Core/Atom/Atom Matrix

Then I receive an error on the serial console and AtomMatrix shows a red X

Traceback (most recent call last):
  File "flow/m5cloud.py", line 82, in _exec_fun
  File "<string>", line 7, in <module>
  File "units/_rgb_multi.py", line 47, in set_screen
IndexError: list index out of range

UIFlow Web v1.4.5
AtomMatrix v.1.6.5
M5Burner 2.1.6

Any ideas how to fix this?

Thanks
Mike

Hello Mike

I don't know if it helps, but I wouldn't mix UIFlow versions. Try selecting beta in UIFlow Web which should match the UIFlow firmware v1.6.5 on your M5AtomMatrix.

Thanks, I erased and re-flashed the AtomMatrix, now using v1.6.5 on device and web editor.

A simple test program is working:

But the official example from GitHub is failing with v1.6.5 (web + firmware).

Hello Mike

it looks like the AtomMatrix example has been replaced and works now. (And yes, the previous example was broken for me too.)

Cheers

Thanks!

it is an old version program compatible problem. now we updated a new example.
