DLP4710EVM-LC: GUI Userguide for Pico Display an Light Control EVM 2.2.0.5, running internal pattern in standart gui

Part Number: DLP4710EVM-LC
Other Parts Discussed in Thread: DLP4710

Hello,

we want to to use the DLP4710 for 1D Pattern, however we are not able to use or to operate the internal pattern option in the standart gui. We alwas get a result, which has has nothing in commen with the input pattern, it isn't even a 1D result. Can you help us here? Are there common misstakes?

In addition to this we can not display splash images with the advanced GUI. The resulst are always the test pattern shown befor and some additional patterns. The additional patterns are different for each splash image, but stay the same when repeatet with the same image. The additional pattern uses the same colour as the splash image, but can't be recognized as the splash image by me or my teammates.

After 2-4 attemps the  image of the projector turns black and doesn't react to any input from the GUI. It can't be restartet using the on and off button.

I hope that my description is understandable.

    Hi Lennart,

    Welcome to TI E2E forum and thank you for your interest in DLP technology.

    Please let us know the firmware version you are currently using. Also, can you just check whether the problems still persist after reprogramming the firmware.

    Regarding the running of internal pattern mode - You have to first program the internal patterns on to the flash, by default the system will display the pre-stored patterns if you directly run the internal pattern mode without adding the patterns you want to display.

    Regards,

    Mayank

    Hello Mayank,

    we were always using the EVM Software 4.2.2 the EVM Firmware 7.0.1 and upgraded from the 2.2.0.5 GUI to the the 2.2.0.6 GUI

    Upgrading the GUI and using the programm the flash option in the GUI worked for some exposur times. We aim for exposurtimes around 2s or 2000000 us. When using such long exposur times, with correct pre- and post-exposurtimes, we are still able to program the flash, but the projector turns black. Afterwards all other option, like showing the simple splash patters, can only be used after a restart of the projector. Is there a maximimum range for the exposur time? Because no warning of a long exposurtime appears in he GUI.

    We still have problems using the advanced GUI. For example a splash pattern is shown multiple times, in a kind of 2x3 matrix. Each cell contains the picture. (Seen in the added picture). Using the standart GUI we get the result as excpected.

    Regards,

    Lennart

    Hi Lennart,

    For exposure time details please follow this thread : https://e2e.ti.com/support/dlp/f/94/t/778576 and let us know if you still have any questions related to exposure time.

    For splash issue, can you send me the commands you are sending in Advanced mode. Also what is the resolution you are using for splash image ? Is it TI's default splash image or did you change the splash image in firmware ?

    Thanks,

    Navneet
