Hi all,
First post so I’ll try and be as accurate as possible.
I recently purchased the ESP32-C3 1.28 Inch Round Display GC9A01 IPS LCD Touch Screen below from AliExpress.
On arrival it is working with the demo so I know its functioning as expected.
I managed to flash it with ESPHome successfully and can upload YAML to it no problem. But when using my basic knowledge and following the schematic and documentation, I can get it to be marked as successful but the screen never displays anything. Even trying something as basic as EspText on the screen.
Schematics atatched below.
YAML CODE:
Completly forgot to add the YAML. Apologies.See below.

Any help/advice would be greatly appreciated!
