pupil remote scripts

README.md

Pupil Remote

This collection of scripts emulates a toolchain where:

• a UDP signal is used to broadcast the beginning of a recording. - udp_broadcast_server.py
• a bridge script relays the information using 0MQ. - udp_serial_bridge.py
• Pupil Capture Plugin Pupil_Remote will start the appropriate fn in Capture.

Pupil Remote can be emulated with test_zmq_server.py

Currently supported controls:

• "R recording_name" : start a recording, sending "R" again will stop the recording
• "T" : set timebase to 0
• "C": start callibration

This is a test server. It will listen for commands and echo them.
