hello all,

Im using the dlp 4000 starter kit.  i want to know if there is a user guide for the kit. I also want to know details as to how the image is displayed. Can someone point me towards documents with technical details about the kit.

thankyou

    Hello Guru,

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

    Yes there are quite a few support documents available.  In order to access the documents you need to request access through the Design House that you purchased the kit from.  The list of design houses can be found here -->   DLP Design Houses

    hello Fizix,

    I got access to the documents now.

    I am trying to program the FPGA on the D4000 controller board. From my understanding I can load the code into the FPGA through the API using the int program_FPGA() function. Am I right?

    Hello Guru,

    Yes, that is correct.  Please see the API documentation for how to use the function.

    Thank you. 

    Another question I had is: When you are uploading an image onto the DMD can the DDC4000 chipset identify what color each pixel is?

    Hello Guru, I think there is a misconception regarding the D4x00 chipsets.  These are binary only.  If you wish to do color then you must use LED's sequentially or a lamp with a colorwheel.  To achive the color bit level your FPGA program will have to handle grayscale PWM (pulse width modulation) during the display of each color. 

    The chipset itself only comprehends a pixel being "on" or "off".

    what I am trying to understand is if the D4000 chipset can identify the RGB value for each pixel

    hello Fizix,

    I am not sure where exactly I would use the functions that are defined in the API programmer's guide.

    I will be programming in C. Do I have to write my own .c file and save the .ocx file in the same directory so that I can call the functions listed in the guide.

    OR

    is it that the GUI provided by TI allows me to some how enter the function directly.

    Thank you for your help

    Guru,

    The D4x00 kits do not comprehend RGB at all only binary bit values.  All RGB (or grayscale) functionality must be implemented by the user on the PC side and/or in the User APPS_FPGA.

    C Programming is fine, but I suggest bypassing OCX altogether and using the D4x00_USB.dll functions at the end of the API guide directly.  For the APPS_FPGA you will want to use the Xilinx ISE development environent to write you VHDL code.  Sample code for the default Pattern Generator and for the GUI APPS_FPGA load can be found on the Extranet.  If you do not have access, please request it from the Design House that the kit was purchased from.
