Linux/DLPDLCR2000EVM: Input Source Problem

Johnny Leung

Part Number: DLPDLCR2000EVM

Tool/software: Linux

HI,

I read the software programmer's guide, then I know that "i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i" means select input source from parallel interface.

The default input source is BBB's desktop. How can I change the input source from BBB's desktop to BBB's buffer or somewhere?

Thanks.

    Johnny,

    What you are trying to do here is a BeagleBone-side problem, rather than an EVM-side problem. That being said, you have a great deal of flexibility here depending on what you want to do.

    With the default software configuration, video pushed directly to the framebuffer will display on the EVM's output assuming you have set the system to do so by inputting "export DISPLAY=:0" in the terminal. Framebuffer output will overlay on top of the desktop in this case. For quality of life, you can also disable the desktop GUI (lightdm) and have the framebuffer output be the only thing to show up.

    I hope this helps. Let me know if you have further questions.

    Best Regards,

    Philippe,

    By writing the framebuffer, EVM can directly read and display what I want to show.

    Thanks for your help!
