Has anyone managed to get ESPHOME to work successfully with a Pimoroni Badger 2040W? And able to give me some pointers?
I’ve got some basic code working with the Pi Pico but I haven’t found a combination to make the display work yet.

This is my current code, it’s been through a few changes but it’s where I am now. I’ve tried different display versions and pin inversions (from looking at the circuit diagram).
As it stands I do not any screen updates at all, the display remains as the Pimoroni examples. All the Pico inputs and outputs work as expected.
I get this error but I cannot find a solution despite reading a number of post referencing the error.
[10:14:00][E][waveshare_epaper:159]: Timeout while displaying image!
[10:14:00][W][component:237]: Component display took a long time for an operation (1015 ms).
[10:14:00][W][component:238]: Components should block for at most 30 ms.
