DLPLCR4500EVM: Questions about projection using LightCrafter 4500

Part Number: DLPLCR4500EVM
Other Parts Discussed in Thread: TIDA-00254

Hello,

We are considering the projection of the pattern using the DLPLCR4500EVM.

Connect camera and PC, PC and LightCrafter 4500 with USB,
Create a pattern on the PC according to the object shot with the camera.
We are considering projecting the created pattern at high speed in real time.

Could you project a pattern flexibly from PC instead of loading from flash memory?

It would be greatly appreciated if you could advise whether the above could be realized using DLPLCR 4500 EVM.

Best Regards,
Leonardo

    Hi Leonardo,

    For our Lightcrafter 4500 EVM, loading/projecting a pattern over USB from the PC "on-the-fly" is not supported. This platform does support video streaming input however. 

    It sounds like you might be considering using this system for some sort of machine vision application? Can you elaborate further on what you'd like to accomplish?

    Just for your reference, take a look at TIDA-00254 and the user's guide for the Lightcrafter 4500 to understand what types of things are possible with this platform.

    Thanks!

    Dear Paul

    Thank you very much for the information.

    Can you elaborate further on what you'd like to accomplish?
    →The object flows like a factory line. The objects are varied.
    Create a pattern to analyze the object using the PC and project the pattern.

    I have read TIDA - 00254.
    However, it takes time to rewrite the firmware of Flash,
    so I thought it was difficult to project in real time while swapping patterns flexibly.

    Does the input using mini-HDMI in video mode can be used as a normal projector?

    Best Regards,

    Leonardo,

    Yes, using the mini-HDMI does allow this to function like a normal projector. It also supports a video pattern sequence mode where video input data can be displayed with desired pattern settings and pixel accuracy.

    If you're changing patterns based on the object type being scanned, then this might be a better option.
