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:

.. zephyr-app-commands:: :zephyr-app: samples/drivers/display :board: stm32h747i_disco/stm32h747xx/m7 :shield: st_b_lcd40_dsi1_mb1166 :goals: build
