I am trying to make a presentation software to present visual and auditory stimuli and to send marks to a electrocardiogram recorder (BIOPAC System). I know runRev can 'write to file "LPT1:"' but BIOPAC waits for a TTL pulse. I don't know where is the lost link. How could I send a code trough the paralel port in a pulse form? Anybody can help me in this topic?
Thanks in advance. I hope to learn a lot in this list.
