FTDI VM800C Embedded Video Engine Board
#######################################

Overview
********

The VM800C is a development module for FTDI’s FT800, which is used to develop
and demonstrate the functionality of the FT800 Embedded Video Engine, EVE. This
module behaves as an SPI slave, and requires a SPI Master for proper
microcontroller interfacing and system integration.

Requirements
************

This shield requires a board which provides a configuration that allows an
SPI interface and an interrupt signal. (see :ref:`shields` for more
details).

Sample usage
************

You can try use FT800 with the Zephyr FT800 sample, which provides
out-of-the-box configuration for FT800 Embedded Video engine.
See :ref:`display-ft800-sample` for details.

Build and Programming
*********************

Set ``-DSHIELD=<shield designator>`` when you invoke ``west build``.
