Initial 2019 beta release. This image includes C++, Java, and Python libraries required for vision coprocessor development for FRC (e.g. opencv, cscore, ntcore, robotpy-cscore, Java 11, etc), and bundles both a default application that performs simple streaming of multiple cameras and example C++, Java, and Python programs to use as a basis for vision processing code. A web dashboard is also included to configure the rPi (e.g. changing network settings), monitor the vision program (console, restart), change CameraServer and NetworkTables settings, and upload vision processing applications, all without the need for SSH. The image has been designed for robustness to hard power offs by defaulting the filesystem to read only mode.

Getting Started:

  1. Download the .zip and use Etcher (https://www.balena.io/etcher/) to image a micro SD card. The micro SD card needs to be at least 4 GB. Note: a micro SD to USB dongle such as https://www.amazon.com/gp/product/B0779V61XB works well for writing to micro SD cards.

  2. Put the micro SD card in a rPi 3 and apply power.

  3. Connect the rPi 3 ethernet to a LAN or PC. Open a web browser and connect to http://raspberrypi.local/ to open the web dashboard. On the first bootup the filesystem will be writable, but later bootups will default to read only, so it's necessary to click the "writable" button to make changes.

Known issues with this release (errata). These will be fixed in the next release.

  • Downloading the Java example program on the web dashboard does not work. Grab it manually from /home/pi/zips instead (using ssh).

  • Console output enable button on the web dashboard doesn't persist correctly through a rPi reboot (it needs to be disabled and re-enabled to again get console output).
