Auxiliary display


This sample shows how to use the auxiliary display driver by outputting a sample “Hello World” text to one.

Building and Running

Note that this sample requires a board with an auxiliary display setup. A sample overlay is provided for the nucleo_f746zg board fly-wired to a Hitachi HD44780-compatible 20 character by 4 line display. See the overlay file samples/drivers/auxdisplay/boards/nucleo_f746zg.overlay for wiring configuration.

west build -b nucleo_f746zg samples/drivers/auxdisplay
west flash

If successful, the display will show Hello World from <board>.
