| 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: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/drivers/display |
| :board: stm32h747i_disco_m7 |
| :shield: st_b_lcd40_dsi1_mb1166 |
| :goals: build |
