[HELP] WaveshareV4 not drawing on PI 02W (Device Busy)

[aalejandrofer]

Hardware

• Pi Zero 2 W
• Waveshare 2.13inch e-Paper HAT v4

Describe the bug
Device Busy

• I have tested the screen on a pi4b and the image draws.
• [Not Tested] I have heard that it has something to do with the screen being connected using the headers instead of wired. I want to avoid wiring it.

I have tested with waveshare_3 but the same

I use the example code for testing is all right, you use the latest example code to see
Do you have other SPI devices using SPI at the same time

Hi! Im experiencing the same problem, V4 and V2 wont work at all on my 2.9inch EPaper module

I also can only epd2in9d and epd2in9b_V3 get to work on it.
Im using an Teensy 4.0 together with the Arduino IDE 2.3.2

Also seems like almost every library which includes "paint" does not work on my device
