DLP6500FLQ: How to load images into flash memory

Part Number: DLP6500FLQ

Hi

I have the 6500 EVM and it works well. How do I load an image from my computer into the flash memory? I want to upload a single bmp image and then display it repetitively. I've read the dlp0028c document on the EVM and it's pretty confusing.

Thanks

Jim

    Hello Jim,

    I assume that you have already used pattern-on-the-fly mode to test the sequence you want.

    You will need to add the images to the firmware and load it as described in §3.9 starting on page 46 in the User Guide.  There is a lot of control with the DLPLCR65000EVM which makes understanding the process a bit complex.

    Please ask about steps that you are not understanding in this section.  PLEASE remember to save the original firmware file and give your firmware file you intend to append a new name.

    Hi Fizix

    Thanks for getting back, let me explain a bit more what I'm doing. I'm using Video mode and my source is an HDMI camera that I interface through the HDMI port. This mode works well

    I can capture a single frame image from the camera and store it on the computer. I now want to play that image back repetitively.

    I'm confused about the file format protocol for the 6500EVM. I'd like to load the bitmap image and initiate a repetitive projection of the same image.

    Jim,

    You can do that without programming the flash with "Pre-stored Pattern Mode".  Simply use "Pattern On-The-Fly Mode".

    Then add the pattern(s) and settings that you want.  Choose "Repeat" on the right and press "Start".

    You can use the "Save" button to save the file(s) and setup.  When you open it next return to the same mode and select "Load" and load the saved information.

    If you wish to display a full color image in this mode you will need some program that can separate and save the R, G, & B color channels and save each channel as an 8-bit grayscale image with the color name.

    Then set the exposure time for about 1/3 of the desired frame time.  Select the Bit Information as 8 bit depth and load the matching image and set the LED color, and then run the 3 "patterns" to get the one color image.

    Even if you use the "Pre-stored Pattern Mode" you will have to build it exactly the same way.  Using "Pattern On-The-FLy Mode" you can test your sequence first.  If you decide you want them stored in flash you can do that later.
