Digital event recorder

Digital Event Recorder

The Digital Event Recorder is developed by the Technical Support Group. The device is based on a Raspberry Pi. It has isolated inputs that can register trigger pulses from other devices. The incoming pulses are timestamped and can be used afterwards for synchronization of data collected from different devices. The device has an Ethernet connection and can be instructed and read out by your MATLAB program. The MATLAB software for the device is available in the biofysica repository on Gitlab.

The synchronization is based on Lab Streaming Layer (LSL). This protocol has a built-in timing facility which is designed to achieve sub-millisecond synchronization on a local network.
