I have a question here. My purpose is to add an OLED ssd1306 in my project.
Hardware:
-
nRF54L15-DK. PCA10156
-
OLED SSD1306 128x64.
Software:
-
ncs v3.0.1
-
Refer to zephyr/samples/subsys/display/lvgl.
The attached file - hello_world.7z, was my testing code. I also attached some screenshots of the Logic analyzer for I2C data.
My questions:
-
I don't know why the display screen arose a snowflake screen.
-
Do you know what the LVGL is related to sdd1306?
BTW:
In order to use the shield_ssd1306 from official sources, I temporarily added "arduino_i2c: &i2c21 {};" in the zephyr/boards/nordic/nrf54l15dk/nrf54l15dk_nrf54l15_cpuapp.dts.
If you know other way without changing it, let me know.
