Before creating a pattern sequence,
make sure to follow the steps in Section 6.1. Download and execute the latest DLPC900REF-SW Windows-Installer, and then start the DLP LightCrafter
DLPC900 GUI application. The GUI detects the attached EVM, and the Connected
radio-button lights up Green indicating
the connection was successful. The GUI software includes sample images for the DLP
LightCrafter Single DLPC900 EVM that are used in the examples in this guide. If the
sample image files have not been unzipped during the installation process, then
within the GUI install directory, unzip the image files to gain access to all the
sample images. All images are 1-bit binary patterns and have the native resolution
of the attached DMD.
Follow these steps to create a pattern
sequence. See Figure 7-7 to identify the buttons on the Menu bar.
- Select Pattern On-The-Fly Mode from the Operating
Mode group box, and click the Pattern Design button so that the
panel is displayed as shown in Figure 6-1.
- Click the Add Pattern button (with the plus sign) in the
Menu bar and browse for any three bitmap images from the sample of
images. The default directory location is C:\Texas
Instruments-DLP\DLPC900REF-SW-5.x\DLPC900REF-GUI\Images and Batch
files\[DMD]_Images. Be sure to select them from the correct image sub-folder for
the EVM that is being used. All three images can be selected at the same time
within the open file dialog window, but may not appear in the same order in the
GUI as in the dialog window.
Note:
For the next three steps a
selected pattern is indicated by a lighter gray selection area. See
Figure 6-2 which shows the third pattern (pattern 2) selected.
- Select the first pattern (pattern 0) within the Pattern
Design panel and choose a bit depth of 1. Set exposure to 100000 µs,
dark time to 50000 µs, and select Red
for the color.
- Select the second pattern (pattern 1) and choose a bit depth
of 1. Set exposure to 150000 µs, dark time to 75000 µs, and select Green for the color.
- Select the third pattern (pattern 2) and choose a bit depth of
1. Set exposure to 200000 µs, dark time to 100000 µs, and select Blue for the color. Figure 6-2 shows the pattern sequence.
- Select the Repeat radio-button to continuously repeat
the pattern sequence.
- Click the Update LUT button to upload the pattern
sequence definition including the three pattern images to the EVM.
- Click the Start button to run the pattern sequence. The
three selected patterns show for the timings entered in steps 3, 4, and 5 and
repeat until Step 9 is completed.
- Click the Stop button to stop the pattern sequence.
