		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``.
