The DLPC34xx controller contains an Arm®Cortex®-M3 processor with additional functional blocks to enable video processing and control. TI provides software as a firmware image. The customer is required to flash this firmware image onto the SPI flash memory. The DLPC34xx controller loads this firmware during startup and regular operation. The controller and its accompanying DLP chipset requires this proprietary software to operate. The available controller functions depend on the firmware version installed. Different firmware is required for different chipset combinations (such as when using different PMIC devices). Go to Tools & Software or contact TI to view or download the latest published software.
Users can modify software behavior through I2C interface commands. For a list of commands, view the software user's guide accessible through the Technical Documentation links.
