DLPR350: Sending images to LightCrafter without re-building the firmware or using the GUI

Part Number: DLPR350
Other Parts Discussed in Thread: DLPLCR4500EVM

Hello,

I am currently working on a project, in which I am using python and MATLAB to communicate with the DLP4500EVM, based on the source code of the GUI provided on your website. I would like to send images from my computer to the LightCrafter for it to display, without using the HDMI connection, but only the USB one. In the GUI source code there are functions to be used in programming mode, including one to upload data to the LightCrafter. I would like to have confirmation that it is possible to send and store images to the LightCrafter that way, without re-uploading the entire firmware in the GUI, and in that case, which address in the memory should be set, and what procedure should be followed regarding the commands to be used. Otherwise if not possible that way, could perhaps recommend another ? I know of this thread https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/198396/matlab-and-dlp-lightcrafter-load-static-image and this related project https://github.com/fglichttechnik/TI-DLP-LightCrafter that allow to send bmp images to the LightCrafter, however without actually uploading the image to the flash memory it seems. So would it be possible to do this with the DLP4500EVM as well, since it is close to what I want to do in MATLAB, however not with the same model of LightCrafter I am currently using, as it appears to be using a different connection protocol (TCP/IP instead of USB for my model).

Thank you in advance for your time and your answer.

Respectfully

Romain

    Hello Romain,

     

    Welcome to the E2E forums and we hope to assist you with your questions.

     

    After looking at your question, we do not support uploading images without updating the entire firmware with our current GUI. I do not know if it is possible to perform what you are asking, we only have the mentioned process in section 3.5 of the user guide which involves updating the entire firmware when wanting to change or add images.

    I will try to look into this more but we do not have any utility to know the address locations of specific sectors of the firmware in the GUI which would be an important step in the method you are asking about. 

    Regards,

    Hello Alexander, thank you for answering. If you happen to find a way to do this I am still interested. Is the other approach unfeasible as well ? What I mean is that I could also be satisfied with just sending images to the LightCrafter for it to display, without storing said image in its memory. I know it was possible with an other version, like in the github project I shared the link of. Is it not possible anymore ?

    Regards 

    Romain

    Hello Romain,

    I do not have any experience with the github project you linked and I am not sure if it is compatible with the DLPLCR4500EVM.
