Welcome to the jAER Open Source Project

Real time sensory-motor processing for event-based sensors and systems

Founded in 2007.

This project has been moved to github at https://github.com/SensorsINI/ . Commits are now disabled here.

jAER Project News.

As of 07 October 2014 the Java code base subversion URL is https://svn.code.sf.net/p/jaer/code/jAER/trunk/ . Remember to check out in a new empty folder. Note that this is for the Java code.

The trunk URL that has all of jAER is https://svn.code.sf.net/p/jaer/code/. This checkout will obtain all of jAER, including windows device drivers, logic designs, bias settings, matlab functions, etc.

To get started, see About jAER and the jAER Installation. For developing in jAER, see jAER Developer Setup. The main help forum is https://sourceforge.net/p/jaer/discussion/631958/.

See browse_pages for a table of contents. The main pages are:

Welcome and introduction

• What is jAER?

Installation and usage

• Software Installation - installing (actually checking out) jAER using version control

• Driver installation - installing USB drivers

• JAEViewer Usage - basic user guide for newcomers

• Sequencing events
• Reading data from recorded .aedat file into Matlab or writing data from Matlab to .aedat files

Developer setup

• Developer setup - mainly for NetBeans, the preferred environment.
• Developer setup Eclipse
• Developer setup Linux
• Developer setup MacOS X
• Developer guidelines - all new developers, please read.

Algorithm and interface development

• Adding new event filters and processing algorithms - most developers will be doing this.
• Adding new chips - if you have a new hardware device that uses an existing hardware interface.
• Adding new hardware interfaces - if you have a new type of hardware interface, e.g. based on USB, UDP, etc.
• Real-time processing - comments about how events can be processed within the hardware data acquisition thread to achieve ms latency.
• Interfacing to jAER - about sending and receiving events over UDP or TCP and remote control of jAER AEViewer and AEChips.
• Preferences - how the current state is saved and restored in Java Preferences.
• List of Event Processing Filters - An (extensive) index of event-processing filters that have been made over the years. Before making a filter, it's a good idea to search here for what's been done already.

Sample data

• Sample AER data - mostly from the DVS128 silicon retina. Externally hosted.

Hardware

• Hardware
• Dynamic Vision Sensor (DVS) - wiki for the Dynamic Vision Sensor cameras.
• The eDVS - user guide for Jorg Conradt's "embedded Dynamic Vision Sensor" (or eDVS) camera.
• AER-EAR event-based silicon cochleas - wiki for silicon cochleas.

• Cables and pin specifications - AER cabling guide showing the Rome and CAVIAR standards.

• Reference hardware designs - reference designs for AER interfaces.

• Bias generators - design kits for on-chip bias generator circuits, for AMS 0.35u and UMC 180nm processes.

Support

• FAQ - frequently asked questions about jAER.
• Troubleshooting
• Documentation

• Javadoc - API documentation snapshot, likely very outdated. Developers should regenerate after setting up development environment.

• jAER Help Forum

• jAER Support ticket system. Use this to post specific bugs.
