I'm new to zephyr and I'm trying to get a 128x32 SSD1306 display working with a stm32 black pill and I'm having trouble.

My prj.conf has CONFIG_DISPLAY=y

My CMakeLists.txt has set(SHIELD ssd1306_128x32) before the boilerplate include.

When configuring I get a "Label or path arduino_i2c not found" so I tried adding "arduino_i2c=&i2c1" to my app overlay file and that didn't help.

Am I missing something in my app code? Or do I need to modify the shield code to accommodate stm32? If so, where would I get started with that?
