Miti:
Here it is.
Lagros:
Try unsoldering R10 and R11 and turn it on without these resistors.

How would it work without pull-up resistors? What do you suspect?
Lagros:
Pull-up resistors are present in OLED.
Try it!

I installed STM32 Cube and tried to change the I2C mode from FastModePlus to FastMode but I can’t figure out how to do that.  :palm:
Moreover, the project doesn’t seem to be the latest one. I guess I’m  :horse:

Miti, this is not enough. It is also necessary to change the frequencies inside the microcontroller buses
The pull-up resistors for the I2C bus and 3.3V voltage are not selected correctly. They should be equal to 1k. You can calculate this using an online calculator.
