Operating the DLP LightCrafter 6500 and 9000
The GUI will allow you to load up to 512 images; however, 112 of these images must be repeated. For
example: open the
add_512.txt
file located in the sample images directory to view the list of bitmap file
names. Notice the file names range from 0_binary to 399.binary, and then repeats 0_binary to 111_binary.
For a demonstration of a 512 pattern sequence follow these steps.
1. Continuing from the previous set of steps, stop the pattern sequence if it is currently running.
2. Click the
Select All Patterns
button to delete all the images from the design panel.
3. Click the
Load
button and select the
add_512.txt
file located in the sample images directory. Be sure
to select the correct file for the EVM being used.
4. Select all patterns.
5. Select a bit depth of 1.
6. Set exposure time to 100000 µs.
7. Set dark time to 0 µs.
8. Select any color.
9. Select
Repeat.
10. Click the
Update LUT
button and wait for all patterns to be uploaded to the EVM.
11. Click the
Start
button to run the pattern sequence.
12. Notice the dots that are displayed run from 0 to 399, 0 to 111, and then restarts from 0
13. Click the
Stop
button to stop the pattern sequence.
Another method of creating a pattern sequence in
Patten On-The-Fly Mode
is using a batch file that
contains all the necessary commands and the compressed images.
Follow these steps to execute a pattern sequence using a batch file.
1. Stop the pattern sequence if it is currently running.
2. Click the
Batch Files
button at the top of the GUI.
3. Check the box to
Enable Command Logging
.
4. Click the
Clear All button
to clear any content in the panel.
5. Click the
Load Batch File
button and select the
onthefly.txt
file located in the sample images directory.
Be sure to select the correct file for the EVM being used.
6. Click the
Execute All
button. Wait for the batch file to execute.
7. Click the
Pattern Mode
button at the top of the GUI.
8. Click the
Start
button.
9. Click the
Stop
button to end this example.
3.6.3 Creating a Pattern Sequence in Pre-Stored Pattern Mode
Creating a Pre-Stored Pattern sequence is very similar to Pattern On-The-Fly Mode. The difference is that
the patterns are pre-stored in flash memory.
If images are not present in the flash memory, proceed to
section to add the images to the
firmware and upload them to the EVM, then return here for steps on creating the pattern sequence.
To start creating a Pre-Stored Pattern sequence, follow the steps in
with the only change in
step 2. In step 2, select the
Pre-Stored Patten
radio-button and then proceed with step 3.
3.6.4 Creating a Pattern Sequence in Video Pattern Mode
Creating a
Video Pattern Mode
sequence is also similar to
Pattern On-The-Fly Mode
. The difference is
that the patterns will be streamed from the input video source. The user must create the video images and
then input them through the RGB parallel interface. The input video source vertical sync will be used as
the triggering mechanism. The input video source must be stable and locked and continuously being
applied, otherwise the firmware will detect that the source was lost and a solid curtain will be displayed.
While the video source is stable and locked, the status box for
Locked to External Source
will remain
checked.
