Here is a library, >> GitHub - luetee/ST7567S_128X64_I2C: LCD ST7567S 128X64 I2C Arduio UNO

Here is a YouTube video, >> https://www.youtube.com/watch?v=YC-wqZnCGQ4

I tested this library, but i didn't figure it out how to use it, any tutorials?

Use the sketch in the site from @groundFungus

I tested it, but it didn't work with my screen.

Hello... the same thing.
An I2C issue ? I tried to find the right address with a scanner code (for example "Programme I2C_Scanner.ino" found here : LOCODUINO - Bibliothèque Wire : I2C)
result : nothing with this device. Would you try too ?

What display do you use?
My display from aliexpress had zener diodes soldered in (which reduced the voltage on the i2c bus to 2.2 volts) and because of this it often froze.

oh oh indeed it's exactly this screen

and if I'm not mistaken I think I'd already read something about this trick. It's just a bit worrying because there's no way back!
But I'll try it tomorrow, it's always better than an unusable screen...
I'll be back to tell the result

and welcome here (great idea really... thanks a lot for this first post!)

How did you solve the problem?

The library didn't work for me!

hello
I didn't use the luetee library but this one:

(hardware : remove D1 and D2 !)

It doesn't look like this library will work properly

I think it would be better to arrange the characters like in an ASCII table and get rid of that terrible "switch - case" operator

I was only able to get this display to work (using this library) with a Nano after removing D1 and D2 from the board. It displays the test patterns fine. I had also tried I2C detect with a Raspberry Pi as I expected 3.3V logic level but it didn't show up with or without the diodes.
