14 Compute Module Configuration Tool for Raspbian
NEC has created a menu based tool for automatically downloading and configuring various components
and settings for Raspbian OS on the Raspberry Pi Compute Module. This makes it easy to configure a
new OS install.
Options include:
• Configuring the UART to allow communications with the host display.
• Downloading and installing the NEC Python PD SDK which provides APIs for communicating with
the host display. It will also install the Python Serial module if necessary.
• Downloading and installing an example Python file showing how to use the SDK APIs to
communicate with the host display.
• Downloading and installing a Python file that provides System Shutdown support by monitoring
GPIO 23 - set low by the display to signal a shutdown.
• Downloading and installing a Python file that provides hardware based Watchdog Timer support
and automatic cooling fan control by the host display.
• Downloading and installing NEC branded desktop wallpaper.
• Disabling Video Overscan.
• Setting the HDMI Pixel (video level range) Encoding to 0-255.
• Disabling the Desktop Screen Saver to prevent screen blanking.
• Setting the GPU Memory allocation to 192MB.
• Updating the operating system and firmware.
• Setting the Keyboard layout to "US".
• Enabling the LIRC (IR decoder) support.
• Installing the KODI media player with remote control using the display's IR remote.
• Installing the Yodeck bootloader.
