ST B-LCD40-DSI1
Overview
The B-LCD40-DSI1 shield provides a 4-inch WVGA TFT LCD with MIPI DSI interface and capacitive touch screen.
Note
The shield comes in different hardware revisions, the MB1166-A09
is utilizing a NT35510 panel controller and shall specifically
use st_b_lcd40_dsi1_mb1166_a09 as SHIELD when building
Prior versions are utilizing an OTM8009a controller and shall
use shield name without postfix, that is: st_b_lcd40_dsi1_mb1166

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 or st_b_lcd40_dsi1_mb1166_a09 and adding
the necessary device tree properties.
Set --shield "st_b_lcd40_dsi1_mb1166" when you invoke west build. For example:
# From the root of the zephyr repository
west build -b stm32h747i_disco/stm32h747xx/m7 --shield st_b_lcd40_dsi1_mb1166 samples/drivers/display
