OpenSesame is among them. Bit 4 is 1 if a button was pressed, 0 if released. In this mode, the button box generates a single character for ANY change in button state – both button presses and button releases generate a character. The bits of each character indicate the current state of the buttons. If you want to get involved, click one of these buttons! It looks like you’re new here. If this doesn’t work, could you please let me know what version of OpenSesame you are running?

For example in Matlab use the bitget function to test if a specific button was pressed:. There is no way to tell if 2 buttons are held down at the same time – you will never get any response other than the 6 shown below. This would typically be done at the time a stimulus event occurs.

If multiple buttons are pushed, the bit for each button will be set to one.

Also, note that Matlab numbers bits from 1, whereas programming convention numbers from 0, as shown in responss tables above. A bit is set 1 when a button is not pressed and clears 0 when a button pressed. First, cedgus set the timeout towhich means that you will get a timeout response after ms, regardless of whether you have actually pressed a button. I am trying to collect a rating using a Cedrus response box and a sketchpad to present the response options.

I actually came across this through your post on the Cedrus forum But I can also understand if you don’t want to invest too much time in getting the Cedrus box to work, of course.

Hi Sebastian, here the settings for my experiment: I would like to set the “duration” of a ccedrus by keypress of the SR response box, and not the keyboard. If you want to get involved, click one of these buttons!

Just to be perfectly sure, if you click on the ‘Edit script’ button, does it look something like this? I have defined the Allowed responses and time out in SR Box Plug-in, the device name is autodetect, but when my experiment runs, no responses were collected.

There are a number of other XID commands that can be send to the response box in this mode.
