VEP Flasher

In order to have a working VEP stimulation grid we wrote this piece of software, which we called VEP Flasher. It can display different kinds of visual stimuli on a normal LCD or CRT screen with a precise frame rate, equal to the refresh rate of the screen.

Stimuli are represented on the screen by rectangles that change their colour over time accordingly with an input source, with an optional text inside. Input sources can be sine or square waves, constants or numeric vectors loaded from text files. More can be added, thanks to the flexible software architecture.

See also VEP Flasher reference manual.
