Implementing Linux DRM drivers for DLPC3433 MIPI DSI Projectors

Note

TL;DR - Technical overview of implementing Linux DRM drivers for the Texas Instruments DLPC3433 DLP-based MIPI DSI projector — covering the three-subsystem architecture (DLPC3433 controller, DLPA3000 PMIC/LED driver, and DMD optics). - An introductory guide to DLP projector integration in embedded Linux graphics pipelines.

DLP-based projector technology has been evolved in multiple areas of applications since it provides sharp, high-quality projections with the potential for 3D capabilities.

Most of them are Texas Instrument chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device.

DLPC3433 is one of the newer DPL-based MIPI DSI projectors which uses most industrial and consumer electronics.

DLPC3433 block has three key sets of subsystems,

  1. DLPC3433, interfaced from front-end SoC or other chipsets via Parallel, DSI for video, and I2C, SPI for configurations.

  2. DLPA3000 is PMIC and High-CurrentLED driver

  3. DMD, digital mirror device for Sub-LVDS output optics generation.

All the above subsystems are required to implement on respective Linux DRM driver stacks to function properly.
