Hi team,
I got a question from customer.
I am using the DLP4500 RGB for my application. I have problems after displaying the video(59.94fps) under video mode(HDMI source) and pattern mode (HDMI source) . Hope you can help me to understand the operation of these modes.I need a stable trigger to be my pattern trigger in my single pixel camera application .The pattern mode can't help me with only 32MB internal flash memory,so I tried the pattern mode HDMI source and Video mode to display the video on my DMD(2 ways).
When displaying my homemade video (The video is made with 2 images ,and make them switch continuously)
First image: 912*1140pixels white pixel at the corner and others are black.
Second image: 912*1140pixels all black.
I used a CW laser to illuminate the corner of the DMD and try to get the reflected signal received from the detector.In my plan ,I should get a stable periodic 30 Hz square wave (Vsync:60Hz and I switch 2 images in a row so it's 30 Hz).
However ,I got an unstable square wave. Sometimes
Thank you very much for your help.
Best regards,
