[quote user="Younes Assouyat"]Which displays are compatible with NRF5340
[/quote]

It is not a matter of what displays that are supported/compatible. They are just speaking I2C or SPI, and the nRF5340 speaks both I2C and SPI.

I don't have an SSD1306 (NB: SSD1306, not SDD1306, in case you are searching for it), so I can't test, but perhaps you can check out this site:

I don't have answers to your specific questions, but I can help you "just debug it". Answering my questions would be a good place to start.

I have used the example of display grove display, it seems to me it is the only example of screens in which I2C is used.
I need to know the following:
- Which displays are compatible with NRF5340
- The example grove_display is valid for NRF5340?.
- What are the necessary file configurations (.overlay, prj.conf Cmake, drivers...).
- What commands do I need to build and flash.

Regards,

What have you done to try to debug it?:

Did you check both display supply voltages?
Do you have an oscilloscope to verify there is activity on the I2C, and does it match what you are writing?
If you don't have an oscilloscope, are you able to talk to other devices using that I2C port?
What sequence of commands are you sending to initialize the display? Did you get that from an example?

Hi,

The name of the display is OLED Display 128x64 v1.1, and the driver it uses is SDD1306.

Best regards,

Hello,

Did you find any drivers for the specific screen that you have? What is the name of the screen?

Is it e.g. the ssd1306?

Best regards,
