button simpletest throws error on PyPortal Titano

[matthewepler]

I'm attempting to run the example file "display_button_simpletest.py" in the Adafruit Circuit Python Bundle (20230511) example directory. It throws an error "Group full." No changes were made to the original code. I did not reflash the firmware, either.

Steps taken:

1. Move "display_button_simpletest.py" to the PyPortal Titano drive
2. Rename file to "code.py"
3. create lib folder and add libraries:

• adafruit_bitmap_font/*
• adafruit_button.py
• adafruit_display_shapes/*
• adafruit_display_text/*
• adafruit_touchscreen.py

4. Error thrown (see output below)

After some troubleshooting, I was able to get the code to run by shortening the length of the button label to just two characters. After that worked, I reset the label to "HELLO WORLD" and attempted increasing the width of the rectangle in increments of 100 up to 800 but this did not work.

As this is an example file, I would assume that it should just work.

Serial output:

code.py output:
Traceback (most recent call last):

@matthewepler can you post the contents of your boot_out.txt file that should be on the CIRCUITPY drive?

I'm curious what version of circuitpython is on your device because Groups have not had a size limit for a while now, so I'm guessing the version you have may be an older one from before that change was made. It's possible you might just need to update to a newer version and then it will be working on your device.
