Is there any chance you could please share the rest of the YAML for your testing?
I’ve successfully compiled and uploaded, but blank screen on the display still. I suspect my board type is set wrong or the backlight isn’t being turned on.

I have a similar problem. the screen is black and nothing is displayed.
I think it might be important - I have version v3.0, and you?

I tried to install open hasp and I succeeded, some kind of night release, https://nightly.openhasp.com

Apparently, there are some features in v3.0. Anyway, I’m glad that I came across OpenHASP, a cool thing.

I also have 2.1. Can you please share the full yaml with the esp32/platform version you are using?

The display is not stable. You have to wait a long time. It doesn’t work every time.

@lboue Is it still unstable?

Yes, it’s always unstable. I’ve given up.
