DLP4710EVM-LC: The purpose of EVM trigger in?

Part Number: DLP4710EVM-LC
Other Parts Discussed in Thread: DLPC3479

Hello TI,

J48, pin 5 is said to have following functions, could you please explain more of its usage?

For light control applications: Reserved for external trigger signal (Input). Applicable to internal pattern streaming mode only.

Question: Can I pull this pin high to start pattern streaming?

 

The 3DR pin on the DLPC3479 can be used as a 3D left or right reference indicator or as trigger input signal for light control application. Could you please explain it more on the left/right reference indicator?

 

A jumperonJ8 and J9 has to be set to determine the use case for this pin. For display application: Connect pin 1 and pin 2 of J8 (DLPC3479Master) and pin 1 and pin 2 of J9 (DLPC3479 Slave). For light control application: Connect pin 2 and pin 3 of J8 (DLPC3479M aster) and pin 2 and pin 3 of J9 (DLPC3479 Slave).

Are my EVM jumpers set for let/right indicator or light control? 

 

Thanks!

    Hello Derlin,

    1. If you configure the software using the GUI you should be able to use the trigger in to start and stop patterns.

    2. The left and right pin is if you desire to stream 3D video. The pin can be used to synchronize the 3D glasses. It is not used for typical 2D display or light control modes.

    3. It You can set the jumpers however you wish. 

    Thanks,

    Kyle
