Pico inky 2.9” E-ink only shows noise

I was experimenting with some boiler plate hello world python examples, found on Pimoroni GitHub. All worked fine until I changed font from bitmap8 to sans and tried to run it. Since then the display can only show the static noise you see in the image. Nothing else was changed in the code else than the font. I’ve tried to clear the display, and I can see that it flashes in an attempt to clear itself but it ends up with same noise. I’ve also tried to set it back to bitmap8 but it doesn’t help either.

Anyone ever had this problem? Any idea where the error might lie? I haven’t attached the code because I’m currently away, but I assume it’s not the code since it’s a hello world script with template code from the GitHub.

That looks to me like you might be trying to initialise the screen with the wrong dimensions?

Please could you post the code you’re running, and the version of MicroPython that you’re using?

You could also try starting from scratch by clearing the board’s flash memory (back up any important files first!): GitHub - Gadgetoid/pico-universal-flash-nuke

I managed to physically break the inky when I tried to debug the hardware. I’m done with hardware, I’ll start farming from now on.
