Table of Contents
Overview
These are the release notes for the following firmware image file:
- Firmware Version: 7.3.1
- Embedded Software Version: 2.1.3
- Generated from DLP Composer Version: 13.13
- DMD: DLP230NP
- Controller: DLPC3436
- PMIC: DLPA2000
Configuration Settings
- I2C Address: 0x36
- DMD Pin Mapping: 1
- Rlim value: 100mΩ
- Optimized Frame Rates: 60Hz, and 120Hz
- Four 2D looks (cool, medium, warm, and other) and one 3D look (3D is qHD resolution only)
- Degamma curve using power law 2.2
- Default CCA (color coordinate adjustment) of an identity matrix
New Features and Changes
- General improvements to image quality performance for some systems.
- Fixed an issue causing image flicker and incorrect output in FPD-Link Mode 7/8 configurations.
Known Issues
- If using a DLPA300x PMIC, the no-LED test sets the PMIC IDAC value to 65% of its maximum current range, even if it's larger than the maximum set LED value. Care should be taken to size Rlim appropriately to handle this case.
Technical Support and Product Updates
Thermistor Processing Documentation
- Using System Temperature via I2C commands:
- Read System Temperature (0xd6)
- Note: The temperature of the thermistor is read in degrees Celsius in a magnitude of 10 times the reading of thermistor. Bit 11 (the most significant bit) denotes the sign temperature. A '0' means a positive temperature, while '1' denotes a negative temperature.
- Example #1: b(11:0) = 000110101010; 426d / 10d = 42.6degC
- Example #2: b(11:0) = 100110101010; 426d / 10d = -42.6degC
- Note: This temperature reading will need to be calibrated per the design and specific thermsitor chosen of custom boards. Offset to determine the true temperature of the thermistor reading. Texas Instruments DLP hardware uses Murata's NCP15WF104F03RC.
