Failure to display pattern sequence
I am able to display static patterns through the lightcrafter GUI, however whenever I try to implement a pattern sequence, the command fails. Any idea what could cause this? I believe I am following the instructions correctly.
have you tried to load 8Bit grey level images rather than 24Bit color images? I went through the same problem and could make it work by using 8Bit images...
Thanks for the reply. You are right. "Pattern Sequence" display mode is meant for 1 - 8 bit images and 24 bit images can only be uploaded through "Static Image" display mode.
Also make sure that you are in 'Auto' trigger mode and selecting the right number of patterns in the GUI as shown in the below image (this will give a 'Command Failure' message if not selected correctly).
Hope this helps!
I have a similar problem. Static images with 24Bit color depth can be easily loaded and displayed. However, when i tried to load and display pattern sequence, i get the "Command Failure" error after pressing "Start" button. I tried 608x684 images with 8Bit and 1Bit color depth. My settings are as follows:
Do you have any idea about this error?
This problem occurs after booting the lightcrafter a couple of times. I don't know the actual reason. It works now after being able to save the patterns as a "Solution" once.
Welcome to DLP section of TI E2E community!
Thanks for the update. I am able to reproduce your error on one of the Lightcrafter. I would like to check the code to see where the error is populating and what is causing it.
I appreciate your patience.
Could you please upload the 1-bit and 8-bit patterns you have created, so I can test them.
Here are the patterns:
Sorry for the delayed response. Were you able to display these patterns?
Divya, I am having trouble loading pattern sequence... besides 1bit/8bit gray scale images, is there other constraints?
Is it possible you post a sample pattern sequence that I can download and try?
Please find attached 1-bit and 8-bit patterns for your reference. Make sure to set the "Pattern Settings" first and then upload the images.
Divya, thanks a lot for the heads up. It works fine now.
I can't upload 4 images, whose bit depth is 1 or 8. I first have set Pattern Sequence, Bit Depth , Pattern Count ,Input Trigger, then upload all, but it doesn't work. Just as the following figure, I want to know where the mistake is, Please help me.

Did you load more than 4 patterns before the above sequence? I am asking because there is a known issue in the LightCrafter GUI v3.8.
The "Command Failed" error pops-up in Pattern Sequence mode when loading less patterns than what was loaded the entire time LightCrafter is "ON", irrelevant of the pattern bit-depth. Reboot the LightCrafter and GUI to successfully upload patterns.
I cannot get my 1-bit patterns to upload to the device in pattern sequence mode. I get a command FAILED message every time. If I use "Display This" I get a garbage image on the wrong led.
Here are my settings:
Welcome to the DLP & MEMS E2E forum.
Is this your screen capture? Do you see an LED color other than red? Did you press "Set" before trying the "Display This"?
Have you verified your image properties? Right click on the xxx.bmp file; select "Properties"; select the "Details" tab. Make sure:
Dimensions 608 x 684
Width 608 pixels
Height 684 pixels
Bit Depth 1
Also make sure that the number of patterns which you select matches the number you specified in the "Pattern Count" box.
