Requirements¶
Your board needs to have a mipi_dsi device tree label to work with this shield.
Usage¶
The shield can be used in any application by setting SHIELD to
st_b_lcd40_dsi1_mb1166 and adding the necessary device tree properties.
Set -DSHIELD="st_b_lcd40_dsi1_mb1166" when you invoke west build. For example:
# From the root of the zephyr repository
west build -b stm32h747i_disco_m7 samples/drivers/display -- -DSHIELD=st_b_lcd40_dsi1_mb1166
