Waveshare 7.5inV2 is it supported in the most recent release? #5059

The problem

I want to build an E-Paper Dashboard for Home-Assistant.

All of the Hardware is working and tested in other combinations. I am able to flash the code to the ESP32 but whatever code parameters I use, I could not get anything displayed on the waveshare display

Hardware:

Driver is set to Disbplay Mode B and Interface conifg 1

I tested: different board-definitons (nodemcu-32s, az-delivery-devkit-v4, esp32dev), different display model configurations (7.50in-bV2, 7.50inV2, 7.50inV2alt) multiple GPIO combinations

The board and the driver are working because I can display something on it when it is connected to an Arduino.

I found some blockposts with similar setups with this hardware. The only difference is mostly that I have an e-Paper Driver hardware version 2.3 . All of the others of an hardware version 2.2

The only physical difference in this version is a new PWR Pin. Based on the recommendations auf the vendor I connected it to 3.3V so this should not be a dealbreaker.

I am very thankful for any help.

I am able to compile and upload both through Wifi and the serial connection. While the display does not show anything, the log output loops:

This might to be a duplicate of or related to #4628. Not sure if my problem is unrelated because I use a the e-Papear ESP32 Driver Board instead of the e-Paper HAT Rev 2.2.

running into issue as well, seems mostly like its a contrast issue or something because the display is very faint. using the yaml from https://github.com/Madelena/esphome-weatherman-dashboard
