I don't own this new device, maybe some other user can create and share their configuration for this new display.

This would be great! Just tell me, if I can support.

Hi - I've just received the Waveshare ESP32-S3-Touch-LCD-5B and it's screen is just what I'm looking for - high density, wide viewing angles.

But I can seem to get it to work with Openhasp and I've tried a few different variations. It seems to running the ST7262 but struggling to get the screen working (I can connect to the wifi of the device, just a blank screen). Can anyone help with this one too as it would be my dream device for around the home!

You need a driver for the CH422G IO-expander. TP_RST,LCD_RST and DISP pins are controlled by the expander.
Maybe try to get the display working in a minimal sketch first before porting the functionality into openHASP.

Hi - thanks. I've the demo's that come with the device so I've a bin file and code, but never had any success configuring openhasp and compiling the code.
