Display for NRF5340

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?

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,

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 agree with user71124,

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:
