SSD1306 (i2c) doesn't work well on nRF7002DK (Linux)

[LiranD]

Hi all,

I trying to print some text to OLED SSD1306 that connected with I2C.

west build -b nrf7002dk_nrf5340_cpuapp samples/subsys/display/lvgl -- -DSHIELD=ssd1306_128x32

I took it from here:

https://docs.zephyrproject.org/3.1.0/boards/shields/ssd1306/doc/index.html#programming

No text printed to OLED display, only full color.

I will glad to some help...

thanks:)

Hello, 

Have you had a look at the Printing to an I2C OLED display using nRF Connect SDK blog post on DevZone? This takes you through details around the LVGL sample. 

Kind regards,

yep, I forgot to mention it. ( Printing to an I2C OLED display using nRF Connect SDK blog post)

I repeated on all the stages again, and now it works.

maybe i missed something in the first time.

Happy to hear! There is always a small step that one misses, happens to everyone.
