Recommended 3rd Party Software
BeagleBone Black Debian Disk Image
This is the basic Debian image straight from the Beagleboard.org website. No additional configuration is required. However, you may need a program such as 7zip to decompress the download file, since it is in a format more common to Linux than Windows.
This is a program that can uncompress many file formats. Necessary for the BeagleBone Black Debian Image.
This is the basic Raspbian image straight from the Raspberry Pi creators themselves. Some configuration is required, but we’ll help you with that. The configuration steps can be found in Section 7 of our Raspberry Pi User’s Manual.
Many of these games made in Python work very well with ELI’s touch screen.
Once you’ve picked up your ELI, FDI is with you every step of the way. We offer support and documentation on our forums and support wiki.
Extended Display Identification Data, or EDID, is the data structure passed from a display screen to a device’s video source. Find out more about ELI and EDID here. .
