Example at ...\ncs\v1.4.0\zephyr\samples\drivers\display does not work with SSD1306 wired directly to nRF9160DK

Hi Craig,

How is your display wired up to your DK?

Are you able to display text or characters to the middle half?

I am working from home today, however, I plan to visit our office on Thursday. Hopefully be able to find a SSD1306 at the office so that I can test a few things.

Best regards,

Håkon

Hi Håkon,

I have the SSD1306 OLED display wired directly to the nRF9160DK as follows:

1. SDA: P0.30
2. SCL: P0.31
3. GND: GND
4. VCC: VDD (switch on DK is set to make VDD=3.3V)

I have had no success in displaying legible characters on any part of the display with the nRF9160DK. I am interested in reliably displaying series of16-pixel/24-pixel high characters on the display. Scrolling and displaying graphics would be nice, but not essential.

The SSD1306 display that I am using is 128 pixels wide by 32 pixels high.

Regards,

Craig

Hi Craig,

Thank you for the update.

Looking at your image it looks like the resolution is somehow not set correctly. Is there any chance that the project is configured somewhere for 64 pixels, instead of 32? Would you be able to share your project files?

I had a brief look at your previous case regarding the display. I noticed that in the recommend code for the CMakeLists.txt, the height was set to 64:   height = <64>;

Best regards,

Håkon

The files are attached here. Is the existence of the sample.yaml file in my directory causing the example to not work because it was written for the nrf52840dk_nrf52840? Does the sample.yaml need to be modified/replaced?

Thank you for the project files, I will look into them tomorrow morning(CEST).

Best regards,
