Matrix Portal M4 Error

[sunbake]

Been following this tutorial using the hardware listed on it, but I'm not getting the Creature Eyes.

It works fine when running the sand demo: https://learn.adafruit.com/adafruit-mat ... -dust-demo
What am I doing wrong?

[dastels]

If it runs the sand demo ok then the hardware is connected correctly and functioning.

You're seeing the circuitPython "terminal" output. The code isn't running for some reason. I suspect some file missing.

Can you post what you see in the REPL when the code runs? That should give a better idea of what's happening.

If you aren't familiar with using the REPL (or even just the serial connection), see

Thank you for the links!

This is what is shown in the REPL:

Code: Select all

Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.
code.py output:
Traceback (most recent call last):
  File "code.py", line 68, in <module>
  File "code.py", line 56, in __init__
AttributeError: 'Sprite' object has no attribute 'height'

Code done running.

Again the code used is directly from here:

Are you running the latest version (7.3.0) of CircuitPython and the libraries/modules from the latest bundle?

If you need to update the contents of the CIRCUITPY/lib directory, be sure to delete everything in it first, empty trash, then copy in the latest.

I too am seeing this same error. I have downloaded the latest bundle and installed into the previously empty lib directory.

>>> %Run -c $EDITOR_CONTENT
Traceback (most recent call last):
File "<stdin>", line 68, in <module>
File "<stdin>", line 56, in __init__
AttributeError: 'Sprite' object has no attribute 'height'

[dastels]

Digging deeper I see that the complaint is about the assignment to height which generally is not the case. The "no attribute"error is typically when you access an attribute that isn't there. Assigning it is how it gets created. I'm looking into it.

Are you running the latest version (7.3.0) of CircuitPython and the libraries/modules from the latest bundle?

Dave

Yes, I am running the latest version (7.3.0) including the latest libraries/modules. I'm only using the recommended libraries that was listed in the tutorial including the 'adafruit_imageload'. The list is found here:

[neradoc]

Tilegrid has its own height property now, which is read only and can't be overridden by a subclass because it's a builtin.
Try removing line 56: "self.height = bitmap.height".

[sunbake]

Try removing line 56: "self.height = bitmap.height".

Oh wow, it works perfectly! Thank you so much!
