1 Overview
The DLP®Display and Light Control evaluation module (EVM) includes a Windows®-based GUI tool used
to control the EVM through SPI and I2C commands. This document provides instructions on how to use
features provided by the GUI tool to communicate with the DLP Display and Light Control EVM.
2 System Requirements
The minimum recommended system requirements for the DLP Display and Light Control EVM GUI tool
are:
• PC with 1.4-GHz Pentium IV CPU or higher
• Windows 7 or greater
• 4 GB of RAM
• 1920 × 1080
• 200 MB of free HD space
• USB port
3 Software Installation and Driver Installation
Download the installer for the DLP Display and Light Control EVM GUI tool. Execute the DLP Display and
Light Control EVM GUI tool DLPPicoDisplayAndLightControl.x.x.x.x.Setup.exe and follow the
instructions for software installation. The driver needed to communicate with the EVM is part of the
installation, so no other installer is needed.
Table 1 lists all the tools that the file setup.exe installs.

Figure 7. IntelliBright Page
The IntelliBright™ page has two sections:
• IntelliBright™
• LED Current
IntelliBright™ is the name given to two image-processing algorithms designed to dynamically optimize the
brightness or power consumption on per frame basis. The IntelliBright™ section lets user changes settings
specific to each algorithm and check which settings are currently running on the EVM.
The EVM has three LEDs whose currents can be changed to reduce power consumption and change the
perceived color temperature of the displayed image. The LED Current section lets user modifies the
current values and see what the EVM is using at any moment.
The following commands are used in the IntelliBright™ section:
• Write local area brightness boost control (0x80)
• Write CAIC image processing control (0x84)
• Write LED output control method (0x50)
• Read CAIC maximum available power (0x57)

4.3.1.1 Set Up External Pattern Mode
Follow these steps to set up External Pattern mode:
1. Enter illumination type, bit depth and number of patterns per frame.
2. Enter required exposure time and dark time.
3. Establish trigger outputs if required.
4. Ensure that the EVM is connected and click Set. If an invalid timings error message displays, adjust
the patterns timings in step 2 to ensure that the timings are within the supported range and click Set
again.
5. To verify that the image projected by the EVM has been updated accordingly, click Get.
6. The frame rate field updates. The frame rate field is not editable. The frame rate mentioned in this field
is calculated as follows:
Frame Rate (Hz) = 1000/[(Exposure Time (µs) + Pre-exposure Dark Time (µs) + Post-exposure Dark Time (µs)) ×
Patterns per Frame] (1)

Help section from the bottom left of the page
4.3.2 Internal Patterns Pages
Internal Patterns streaming mode involves projection of patterns created internally by the functional block
of the controller. Select a group of one row or one column patterns to be replicated through the array by
the Controller. The order of display of groups of patterns is configurable.

After setting the pattern order table and the pattern orientation, the user can either load the pattern data
directly flash to run the patterns or save the pattern data on the computer to update the firmware later.
Review the timing diagram to ensure that the patterns and trigger signals are output as desired.
NOTE: Trigger controls available on this page are used to draw the timing diagram only, they do not
affect the functionality of the EVM.
