Connecting to DMD controller directly via hardware?

I'm looking to purchase a DMD and controller (possibly the DLP3000 or the DLP6500). Is it possible to switch between patterns with the hardware or does it need to be done with the TI software? Ideally I would like to be able to switch between binary patterns on the DMD by sending in a TTL pulse (or some other input signal) from another computer program (that's running the rest of my experiment). Is that possible with these devices? If not, is it possible to at least begin a sequence of patterns stored in the controller with some trigger from a different program in the computer? If so, how precisely can we know the timing of this (is there a lag and if so is it constant)? Thanks!

    Hi Tori,

    Yes, this is possible with our chipsets. I recommend purchasing one of our evaluation modules, which will help you get started using our products.

    DLP3000: Lightcrafter - www.ti.com/.../dlplightcrafter
    DLP6500: LightCrafter6500 - www.ti.com/.../dlplcr6500evm

    You can find more information about triggering in the EVM user's guide. For example, take a look at section 2.8.1 Internal Stored Pattern Sequences in the LightCrafter user's guide for information about triggering the pattern sequences with that platform. The programmable trigger delay is discussed in this section as well.

    Thanks,
    Clinton
