DLP4710EVM-LC-FW

Overview

The firmware is primarily intended for the DLP4710EVM-LC evaluation module, but can be used for any DLPC3479 dual-ASIC system with the following configuration:

• DMD: DLP4710LC
• Controller: DLPC3479
• PMIC: DLPA3005
• Illumination: 3-LED (RGB)
• I2C address: 0x36
• DMD pin mapping: Option 1

Release Information:

• Firmware version: 8.3.0
• Embedded software version: 4.6.0
• Light Control sequence database version: 0.1.12

Updates in this release:

• In case of Internal Pattern display using "Trigger Ins", software will not process "Trigger In" pulses when the "Pattern Ready" signal is in deasserted state.
• BUG fix: "Internal Pattern" display using "Trigger Ins" stops abruptly after sometime
• BUG fix: In "Internal Pattern" display, patterns in pattern set are not advancing, where only 1st pattern is shown
• BUG fix: Power cycling required to display new additional internal pattern sets (which shouldn't be the case)
• Changes in existing commands - Read System Status (0xD1), additional light control error codes added:
• 6h: Max Pattern Order Table entries exceeded.
• 7h: External pattern period error.

Known limitations

• The pause/step functionality of internal pattern display should be used only for debugging/testing purposes.
• Non-linearity seen in 8bit pattern display in LC modes when pixel value changes from 127 to 128.
• Power Down Risk during Power Up - User need to wait until after HOST_IRQ has been de-asserted to power down the system.
• External Streaming - Signals/Patterns Incorrect in case of VSYNC jitter.
• Cycling between Pause and Resume for the pattern streaming leads to artifacts.
• Unable to operate DLPC3479 projector after sending wrong splash input image size.
• When switching from internal pattern mode to splash pattern mode make sure that the internal pattern display is stopped.
• While using the update firmware feature of GUI, make sure that size of splash image is as small as possible and prefer selecting RGB color space if the images are of PNG format.
• LC splash pattern display is only supported in RGB format.
• Only RGB888 input source format supported in External Pattern Streaming Mode.
• Unsupported Features:
  • Keystone
  • Sub-image position
  • Image rotation
  • Image Freeze on Splash Screen
  • DSI/BT656 Input
  • CPU Interface
  • LABB with Ambient Light Sensor support
  • Shallow Gradient
  • White Point Correction
  • I2C at 400KHz
  • Flashless configuration
  • Idle mode
  • Power management, clock gating and scaling
  • CAIC is not supported in LC, system will not boot up in LC mode with CAIC enabled
