Hi Steve, It may look as a dummy question, but do you have a display connected to your board ? 
 user114807 said: dev = DEVICE_DT_GET(DT_CHOSEN(zephyr_display)); 
 This line means that, in your board's dts file, you have a node named "zephyr_display" that you can instantiate inside your program. 
 Take a look here or here for more information on dts, here for a few information about SSD1306, and here for another related topic.
