lib needed to work on an M0 #1

Thanks for what looks like such a fun example + which should be far easier to implement that my feeble old-man fuddles. I have a 32x32 linked to an Adafruit LED Matrix Shield, which is linked to a Metro M0. I must be missing something very basic in the "lib" file for CircuitPython 5 on the m0, because when I try running the code I get: File "code.py", line 5, in ImportError: no module named 'rgbmatrix' Doing a quick search in the "lib" folder for CP 5.0 extracted from CircuitPython.org, I don't see a file named rgbmatrix. And when I try to run simple Hello Word-style code at: https://learn.adafruit.com/circuitpython-display-support-using-displayio/text I get: File "code.py", line 6, in AttributeError: 'module' object has no attribute 'DISPLAY' Could you kindly provide info on "lib" configuration or anything other special config I may be missing to use this with an Metro M0 and an Adafruit RGB Matrix Shield for Arduino. Again - sorry to trouble you + thanks!

hello! rgbmatrix is part of the core, which means that it's included in the uf2 bootloader by default like time, board, etc., so I would try updating the version of CP that you're running on the m0 to 5.3 just in case since it's fairly new: https://circuitpython.org/board/metro_m0_express/

Yes, this is the version I've got. As fresh as fresh can be. Perhaps it's not clear, but maybe the M0s don't support this product for CircuitPython? I may not be doing this right, but I tried this from the REPL: import board dir(board) and get: ['class', 'A0', 'A1', 'A2', 'A3', 'A4', 'A5', 'D0', 'D1', 'D10', 'D11', 'D12', 'D13', 'D2', 'D3', 'D4', 'D5', 'D6', 'D7', 'D8', 'D9', 'I2C', 'MISO', 'MOSI', 'NEOPIXEL', 'RX', 'SCK', 'SCL', 'SDA', 'SPI', 'TX', 'UART'] no DISPLAY, which should be there, right? This is why the basic Hello World code isn't working and might be related to why I can't get the M0 with shield working with what I'm sure is awesome code you've written, above? What HW did you use? Thanks!

gotcha, okay tried with my M0 (had prototyped with a feather m4, metro M4 and M4 airlift) and had same issue. and you hypothesized correctly, looks like the M0 does not support the rgbmatrix in its core unfortunately: https://circuitpython.readthedocs.io/en/latest/shared-bindings/support_matrix.html

I'll make a note of this in the documentation for this. Not sure if you have access to an M4 but that should work plug and play.
