Allows you to echo input codes to a port of your choice via TTL signals. To do so, create a file called ttlEcho.txt (see example attached below) and place it in your folder along with the main input file. The text file should contain the port address (as a decimal value, not hex), and the time (ms) for which to send the signal.
e.g., Let's say ttlEcho.txt is present and contains:
Now let's say that the subject presses the space bar (code = 57) on a trial where that's a valid response. DirectRT will immediately send "57" to port 888 for 10ms.
Enhanced voice recording functionality will now allow for manual recording times. This will allow a subject to press a key when they are done speaking to end the recording. To use the new feature, simply add a valid keycode to a fixed length audio RT. e.g.,
In this example, DirectRT will record for up to 5000ms or the point at which the subject (or experimenter) hits the spacebar--whichever comes first. This will only work with fixed length audio RTs. See example stroop manual.csv attached below which can be placed in the voice RT sample folder:
Code:
C:\DirectRT\Samples\5 other features\12 voice responses stroop
