Hi Ada fans. Happy Halloween 🦇 Made an LED Matrix Display (128 x 64) some time ago for fun and set it up for a Halloween window event. Enjoy 🎃

This looks great! Can you give some details on the enclosure and build?

Hi John,
I do apologise for my slow response, I have been on an amazing South East Asia journey and I am now in Canada sliding down snowy ☃ slopes, I have only today logged in and seen your post 😔.

The box is made up of two PVC junction boxes painted black. Inside is an Interstate75 board connected to two 64x64 HUB75 LED displays config 128x64. I will install the IR proximity sensor soon so that the display activates when something passes by. (It made the cat jump ... ☺)

I set this up to run a Slideshow, coded as per "Creating Slideshows in CircuitPython by Anne Barela", worked super good ☺.

However, when I moved from the slideshow to "Code the Sprite Sheet Animation Display" by yours truly, I ran into an error I have not seen before. The code lines (I am presuming) which appear to be the area of interest.
# --- Display setup ---
matrix = Matrix(bit_depth=4)
sprite_group = displayio.Group()
matrix.display.root_group = sprite_group
The "display" attribute has me confused.

I have added some images for clarity, trust they help. I ported the RGBMatrix config I used in the slideshow over to the sprite code and incurred this error. I would truly appreciate your advise.
Again, apologies for the late reply.

CURRENT STATUS.
CP version 9.2.1
I have updated all of the library folders and files listed in the sprite project library with the latest CP library folders/files accordingly.
