serLCD error

I’m unable to get this working]. Tried it with 2 different qwiic connector cabless and on different pins on two of my Picos. Same result. I see text when I start it up, but then just white blocks. Running the attached code I get the error as noted. Saw the reference above to SPI mode but no idea where to find how to reset that. Looked at all the available documents you have online for the lcd o9067 but don’t find anything like that. Do I just have a bad unit?

Make sure the i2c/serial ports are enabled on the Pi - do you have any other microcontrollers to test the LCD with (besides a pico)?

The ports are enabled on my Raspberry Pi, and there isn’t a need to do that on the Pico itself, right? I’ve been following the tutorial in the “Getting Started” document. And I have tried this with 3 different Picos with the same results.
