DLPLCR9000EVM: DLPLCR9000EVM : TCP/IP code for MATLAB

Part Number: DLPLCR9000EVM

Hi. 

Currently, I work with DLPLCP9000EVM. I want to control this in MATLAB (2014a version) via TCP/IP. 

I tried this code below, but failed. 

tcpObject = tcpip('192.168.1.100', 21845)

fopen(tcpObject);

error message was this.

Unsuccessful open: Connection timed out: connect

Is  the number "21845" also working with DLPLCP9000EVM ?

thanks. 

Best Regards, 

Jihee

    Hello Jihee,

    Welcome to the DLP section of the TI-E2E community.

    Thank you for your inquiry.  We will get back with you after verifying whether this method will work with this EVM or not.  We will attempt to get back to you early next week on this.

    Hello again Jihee,

    The engineering team for this platform (DLPLCR6500EVM & DLPLCR9000EVM) have verified that the communication on this particular kits is over USB HID and does not use TCPIP protocols.

    Therefore, this method is NOT supported by these EVMs.

    Hi. Thanks for the answer.
    then, How can I communicate with DMD through MATLAB ? Other communications also not supported ?

    I tried to use video mode and just using DMD as multiscreen, but its speed was too slow(30Hz with HDMI, 60Hz with display port) 

    Also, someone said to me if I am using video mode, DMD would work like rolling shutter not glober shutter.(I don't know the proper words for this.) 

    What I want to do is just giving binary pattern(0,1) with feedback loop. 

    I hope to hear from you soon. 

    Thanks.

    Hello Jihee,

    You will need to download the Firmware and Source code for your EVM which is in C++ from the DLPLCR9000EVM page:

    Choose the top item in the table.

    You will then want to also download the Programmers guide from this page:

    http://www.ti.com/product/DLPC900/technicaldocuments - scroll down the the "User guides" and select the top item.

    You will need to build Labview code to wrap around the C++ functions.  There is no already built MatLab code for this.
