DLP4710EVM-LC: Problems about ttl trigger

Part Number: DLP4710EVM-LC

Hello everyone,

I'm trying to use DLP4710EVM-LC to project video form a PC. I want to use trigger to synchronize projector and the camera. Here I have two opinions. First I can use a 5V trigger to camera and projector to start them at the same time. Second I can start the video manually and use the projector to trigger to camera. Which way should I use? And how?

Thank you!

    Hi Zekai,

    Note that the Input Trigger is applicable only for internal pattern mode as seen in below image from users guide. SInce your use case is display a video from PC it is not applicable. So it is better to go with the second approach and make sure the trig out signals are mapped properly with expected timings.
