Hi all,
I got a 1.69 inch ST7789V display from:
https://www.aliexpress.com/item/1005005238299349.html?spm=a2g0o.order_list.order_list_main.11.34c81802f1viOD

and I am trying to test it on Arduino or ESP32, I didn't get any code yet, can I just wiring 3.3v and GND and let it light up？ I have trid this way by a Adapter Board 0.5mm To 2.54mm doesn't, why?

or any clue to do basic test?

Thanks
Adam

I would take a SWAG and say that is a command that needs to be given to the display. That simply states you need code to make it work.

Good luck. Check if using a library, most have either test code or examples.

great.
thank you.
tested it by TFT_eSPI.h with config of: SETUP ESP32 WROOM 32D with ST7789V AND TFT_eSPI library - #5 by Wolfthere - PlatformIO Community

nothing happened.

tested the st7789v.h with example: graphicstest got error:

Error compiling for board ESP32 Dev Module.

what is it?

does a bare TFT need some special Library?
