DLP4710EVM-LC: Unable to set 2D Random Noise Pattern bmp image as Splash Frame

Part Number: DLP4710EVM-LC
Other Parts Discussed in Thread: DLPC3479

Hello everyone!

I'm currently trying to display a sequence of 2D random noise pattern as splash frame, because I'm aware that my DLPC3479 only support 1D high-speed pre stored pattern display. Then that's why I'm currently trying to set this pattern in the spalsh frame memory.

I'm using:

EVM Software: 4.4.0

EVM Firmware: 8.1.0

GUI Software: 3.1.0.7

Nevertheless, when I'm trying to set this in the Edit Firmware Section -> Step 3: Splash Image once I tried to generate the new firmware file I have two major errors:

1- Flash Builder returned with error code 24

2- If I load only one image in splash image section,  sometimes I dont get the last error, the firmware is generated, but once I tried to switch to this Splash Image in Display section, I get an error:
[Set Splash Image Error!
'Write Rgb Led Enable' command execution failed.
Error Details: Failed to write I2C port via Cypress USB-Serial adapter]

What I'm missing here?

The projector is not even able to display intrincated 2D patterns in Splash Frame?

    [UPDATED]
    In the major error number 2, the device does not display any image and gets completely block when I'm trying to display it from the DISPLAY section. Nevertheless, in the LIGHT CONTROL section -> Splash Patterns, I successfully displayed the image, but then the device gets completely blocked.

    Hello Luis,

    Welcome to the E2E forum and thank you for your interest in DLP® technology!

    Unfortunately this is a known issue with the GUI that we are currently debugging. We do not yet have an expected release date for this fix.

    Kind regards,

    Austin

    Hello Austin,

    Thanks for your reply, so then how can I upload different splash frames (firmware generation), download and then switch them?

    I guess it is related to the API usage, right?

    How can I do it?

    Hello Luis,

    Are you asking how the Splash Patterns section in the Light control section of the GUI is supposed to work? Are you asking about the internal patterns section under light control in the GUI?

    Regards,

    John

    Hello John,

    I'm specifically asking about how to sort the issue number 1 (in my first post), becuase under the the firmware section in Edit Firmware, when I tried to upload the Splash Images I get an error creating the firmware image:

    Flash Builder returned with error code 24.

    How can I create a firmware with those images without the GUI?




    In addition ... I was able to create a firmware when only one two Splash images are uploaded, but under Splash Patterns section in the Light control section if I tried to set the SPlash Pattern to Image Index 1 (noise pattern) the DLPC I2C comm gets blocked and then everything failed, but it doesn't happend with a normal company logo image Index 0, it switches without any problem.

    I can provide the firmware image if is needed, also the Splash noise pattern images.

    Hello,

    This part of the GUI has some known bugs that we are working on currently.

    There is not another way for you to change the FW like you mentioned above.

    Regards,

    John
