Initialize Communication Between Raspberry Pi and EVM

Start the system from an untouched boot state. Plug in the DLPDLCR230NPEVM, followed by the Raspberry Pi via USB to the laptop. After a few moments the USB connection should initialize to the laptop and communication via remote SSH may begin. The Raspberry Pi starts out at its home directory. For reference, this is located at:

/home/pi/

Navigate to the directory which includes the downloaded Python scripts. In this example, the following directory is assumed:

/home/pi/Documents/dlp

Execute the following to navigate down each directory:

$ cd /home/pi/Documents/dlp

Back up navigation by one directory can be achieved with following command:

$ cd ..

Executing the “ls -l” command to ask the Pi to print out the contents of the current directory:

$ ls -l

To initialize the default Raspberry Pi to EVM connection, execute the initialization script via the following:

$ python3 init_parallel_mode.py

Dialogue will print in the terminal while the script is working. Upon completion of this script the Raspberry Pi desktop should be visible on the EVM’s projector output.
