Introduction

The UsbParMarker is an custom-designed open-source USB-controlled replacement for the old parallel port (LPT), a legacy interface still used in certain research fields. It can be used to send 8-bit markers and control TTL devices with sub-millisecond timing via its female DB25 output.

See the Github repo for more information, including E-Prime, OpenSesame and Python usage guides.
