DLP3021LEQ1EVM Evaluation Module
TI's DLP
®
technology offers a fully programmable and high-resolution solution for automotive dynamic ground
projection (DGP) applications. With nearly half a million addressable pixels per module using a WVGA (864
× 480) input resolution, DLP technology exceeds the resolution of existing ground projections technologies.
Dynamic ground projection technology, with the ability to display any static or video pattern within the same
module, can re-invent consumers' perceptions on small projector lighting by providing new, innovative lighting
capabilities. Examples include automotive light "carpets" that can illuminate the surrounding area outside a
vehicle or project vehicle information such as the EV charge level and range remaining, tire pressure warnings,
traffic warnings, turn signaling, check engine light warning, gas level/range, etc. from a side mirror. Ground
illumination has other enhancement features to help cars communicate with drivers and pedestrians, including
corner lighting, reverse lighting, vehicle customization, and parking indicators.
The DLP3021LEQ1EVM is the DLP3021-Q1 Light Engine Evaluation Module (EVM) that allows for accelerated
evaluation of the DLP3021-Q1 chipset with the inclusion of a DLP3021-Q1 light engine. This module brings
together a set of components including the DLP3021-Q1 DMD, the FPGA based DMD controller, and the
TPS65100 PMIC to provide an efficient system for evaluation of dynamic ground projection technology. When
combined with a computer for GUI control, the evaluation module can be used in a laboratory setting to
demonstrate features such as:

Q1 chipset. 1.1 Introduction The DLP3021LEQ1EVM Evaluation Module (EVM) is a complete electronic and optical subsystem designed to control and interface with the DLP3021-Q1 chipset. The DLP3021-Q1 interfaces with an FPGA based DMD controller. This chipset is combined with illumination and projection optics, and RGB LEDs to create a projector that offers brightness of up to 30 lumens with full motion video playback in a small volume form factor. -

This mode is unsupported by the EVM and should not be used. To allow the SPI Adapter board to set the operating mode, TI recommends the DLP3021LEQ1EVM electronics board S1 switches always be set to Local Host Control mode. This is because the On-state of either board will always override the Off-state of the other board. -

Page 15: Software
DLP Composer for DLP3021-Q1 is a software tool that allows users to configure and generate firmware flash data for the DMD controller of the EVM. In the case of the DLP3021LEQ1EVM, the firmware file generated is specific to the FPGA based DMD controller, and loaded into external SPI flash memory. The DMD controller executes commands to read image/video content from the SPI flash memory, and processes the content into the Data Rate (DDR) interface format compatible with the DLP3021-Q1 data bus. -
