Has anyone managed to get one of these working with ESPHome? I bought one but I am struggling to get it to work. I can load the code but unable to get the display to work.
Your display GC9A01 and touch CST816D are both supported, so should be doable.
Also, have a look here:

If someone has gotten this to work please post your code. I can get it to compile and upload but it would never fully boot if I remember correctly.
Hey, I got it to work finally. See the code below. still needs a bit of work but right now this is a basic clock that is displaying the correct time pulled from HA.

I’ll post back here as I get more of the functions to work.
Note for me the thing that got it working was holding down the boot button on the back while powering on. Before that I was having issues with boot loops.

Where you able to upload using web.esphome.io interface? There instruction show using Arduino and I’ve not been able to connect using the ESP home web tool.
