I watched this video
According to the instructions on the website, I successfully connected Arduino nano and GC9A01, and successfully lit up the test circuit.
When I successfully installed in the ARDUINO IDE https://github.com/adafruit/adafruit_gc9a01a This driver library.
Try to reproduce the adafruit as shown in the video_ When driving the example circuit of gc9a01a, but the screen cannot be lit up.
I don't know why,Can anyone tell me why? thanks

Hi @icespirit,
Sorry, I don't have any of the three units mentioned, so I can only look at stuff on the web. When I did this, although you have included some photos, I still became a little confused as to which website you were using for instructions and so on.
Perhaps it would help if you carefully listed the website address, etc for each step, so that anyone looking at the forum can follow the steps, and see what you are looking at.
Best wishes, Dave

@icespirit Sorry I don't read that language. Can you translate?
Also, IIRC, there are two variations of that module, go have a look at Bill's video again and find where he describes what the differences are and how you should address them.
