DLP2021LEQ1EVM Evaluation Module
TI's DLP
®
technology offers a fully programmable and high-resolution solution for automotive dynamic ground
projection (DGP) applications. With an effective input resolution of 588 × 330, 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 projection has other enhancement features to help cars
communicate with drivers and pedestrians, including corner lighting, reverse lighting, vehicle customization, and
parking indicators.
The DLP2021LEQ1EVM is the DLP2021-Q1 Light Engine Evaluation Module (EVM) that allows for accelerated
evaluation of the DLP2021-Q1 chipset with the inclusion of a DLP2021-Q1 light engine. This module brings
together a set of components including the DLP2021-Q1 DMD, the FPGA based DMD controller, and the
TPS65100 PMIC to provide an efficient system for evaluation of dynamic ground projection technology. The
DLP2021LEQ1EVM includes RGB LEDs, while the DLP2021LEWQ1EVM includes a single white LED. When
combined with a computer for GUI control, the evaluation module can be used in a laboratory setting to
demonstrate features such as:

    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 DLP2021LEQ1EVM 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.

Though the LED driver of the EVM is capable of driving above 1 A per channel, TI does not recommend driving beyond 500 mA for extended periods to prevent damage to the EVM due to individual component temperature ratings and thermal management limitations.

  • Page 16: Software

    DLP Composer for DLP2021-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 DLP2021LEQ1EVM, 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 DLP2021-Q1 data bus.
