6.2 Creating a Simple Pattern Sequence
Before creating a pattern sequence, make sure to follow the steps in
latest
DLPC900REF-SW
GUI detects the attached EVM, and the Connected radio-button lights up
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
1. 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
2. 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.
For the next three steps a selected pattern is indicated by a lighter gray selection area. See

which shows the third pattern (pattern 2) selected.
3. 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
4. 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
5. 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
6. Select the Repeat radio-button to continuously repeat the pattern sequence.
7. Click the Update LUT button to upload the pattern sequence definition including the three pattern images to
the EVM.
8. 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.
9. Click the Stop button to stop the pattern sequence.
