Hello TI!
I ask about the following problems. Please resolve this problem.
1 Issue
1.1 Problems where projected images are overlapped or solution file is not recognized when using two solution files(*.ini) alternately for long time(about 3 hours or more).
2 Operating Condition
2.1 Using the DLP350 controller on a custom board. It is communicating to the host PC via USB.
2.2 The images to be projected is stored in the flash memory.
2.3 First solution file(*.ini)
a Pattern sequence mode. Use of images stored in flash. Pattern exposure and period 40ms. Internal trigger(See projected image Fig.1)
2.4 The second solution file(*.ini)
a Pattern sequence mode. Use of images stored in flash. Pattern exposure and period 40ms. External trigger(See projected image Fig.2)
2.5 Applying the 1st solution file → Projection about 5 seconds → Applying the 2nd solution file → Projection about 5 seconds. If I repeat this process for more than 3 hours, the issue is caused.
2.6 ‘Image Load Timing’ was confirmed to be around 100ms. R, G, B channels are extracted and used in one image. So I think the ‘Image Load Timing’ is not a problem.
