DLPLCRDC4422EVM: Hyper-Spectral Image application (Custom Pattern Generation, HDMI Input, I/O Trigger for Camera Sync)

Part Number: DLPLCRDC4422EVM

Dear TI support team,

We are developing a Hyper-Spectral Image device for spectral cell characterization. To this purpose, a DMD will be used to "slice" sample image in vertical bands.

We have acquired the DLPC4422EVM + DLP670TE, however, once we performed start up procedure per the user's guide, and went through the related posts in the forum, we have spotted some limitations:

  • No custom pattern generation capability, either statically or dynamically loaded
  • No HDMI input, and no HDMI to Vx1 front-end readily available (only included with DLPC7540EVM).
  • No I/O trigger for camera sync advertised as a feature (however, there may be access to a sync signal for camera)

Moreover, after further research, it seems that a different platform based on the DLPC900 controller would be the right choice, or at least better suited to our application requirements. The so-called LightCrafter DLP6500 and DLP9000 devices features pattern generation, HDMI input and I/O triggers for camera sync.

So...

Are the above analysis and conclusions correct?

Do we need our own front-end with Vx1 output to send video patterns to the DLPC4422 EVM?

In such a case, is that the recommended way to generate patterns that will have to be synchronized with a camera?

Should we consider moving on to the DLPC900 LightCrafter platform?

Thanks and best regards,

Marcos.

    Marcos,

    Your conclusions are very accurate for the current state of the EVM you have, as are your thoughts about the DLPC900 platforms.

    Currently, I would recommend that you consider the DLPC900, since it has many of the features you are already looking for.  You can preload from Flash or upload patterns from the PC or stream them over HDMI/DP and even define which data from each video frame you wish to show.

    It also has input and output trigger options.

    The DLPLCRC900 EVMs may currently have limited availability also, but there are also offerings from some of our design partners that may get you going:

    If you still wish to know more about Vx1 let us know.
