Example Application

A quick and simple method for evaluating the DLP LightCrafter Display 2000 EVM is to use available video players on Debian to playback a sample video. After completing the quick-start setup, one should use FileZilla (https://filezilla-project.org/) or a similar FTP application to access the BeagleBone Black and upload a compatible .mp4 video. If the system fails to load the DLP LightCrafter Display 2000 EVM as an output monitor, the following commands can be issued to configure the system to external video mode at the appropriate nHD resolution:

i2cset -y 2 0x1b 0x0b 0x00 0x00 0x00 0x00 i

i2cset -y 2 0x1b 0x0c 0x00 0x00 0x00 0x1b i

To play the video, software such as mplayer or vlc is necessary and can be acquired using "apt-get" in the terminal (use "man apt-get" to see how to use the apt-get package manager). In the terminal, the user should execute the following:

  1. The existing desktop is “0”
    1. "export DISPLAY=:0"
    2. "mplayer <file>" OR "vlc :0 <file>"
  2. Generate a new x as “2” if there is no fb being created
    1. "xinit -- :2"
    2. "mplayer –vo x11 <file>" OR "vlc –x11-display :2 <file>"

To automate this process, we can employ sample scripts provided on the BeagleBone Black operating system. To find them, navigate to the directory "/opt/scripts/device/bone/capes/DLPDLCR2000/" and follow the README.txt file there to install the dlp_lightcrafter-1.0.19.tar package. Once installed, navigate back to the "DLPDLCR2000" directory and invoke python to run a script on the system. For example:

  1. "cd /opt/scripts/device/bone/capes/DLPDLCR2000/"
  2. "export DISPLAY=:0"
  3. "python MplayerTest.py"
