DLP lightcrafter 3000 Matlab Code for framerate control

Other Parts Discussed in Thread: DLPC300

Hello Everybody,

I looked at the Matlab Code Jan Winter has posted (Link), but I need to specifically need to run this device around 10Hz and I am confused on how to send those types of commands through matlab.

    Hi Alonzo,

    TI does not support this MATLAB code, so hopefully a community member who uses it can comment on your question. Is there a reason you are trying to use the MATLAB code over the GUI tool provided?

    You can find more information about how the GUI sends commands to the LightCrafter through the DM365 on board in the DM365 Command Interface Guide (www.ti.com/.../dlpu007). The DLPC300 Programmer's Guide would be helpful to take a look at as well (www.ti.com/.../dlpu004).

    Thanks,
    Clinton

    Hello Clinton,

    I could probably just use the GUI, but I would prefer Matlab so I can have all my code in one place.  I just need to load in a bmp file that creates a tile pattern and have that specific tile in the framerate mode, as in on and off at a certain rate.  Is that feasibly possible

    Thanks,

    Alonzo Espinoza

    Hi Alonzo,

    Loading a pattern and displaying it at a specific rate is a basic feature of the LightCrafter. I hope you have been able to move forward with your project with the information and resources we provide. Please take a look at the LightCrafter user's guide if you have not done so already.

    Thanks,

    Hello Clinton,

    This also goes to anybody who have an opinion.  I want to using the movement of the mirror to create a scan like effect.  How can use the GUI to do so?

    Hi Alonzo,

    If you create a set of patterns you can load or stream them to the LightCrafter and it can cycle through them. If you wanted to scan a vertical bar, for example, you can create several images of the bar, having it traverse the projected area.

    You can actually find example images to do this in the LightCrafter SW bundle under <install directory>\DLPLCRSoftwareBundle-3.0\API-SampleCode-v2.0-Windows\Images\PatSeqImages. There are 8 1-bit patterns there that you can try. Look at the pattern sequence mode section of the user's guide for more details to load and run these patterns.

    Thanks,
    Clinton
