Thank you for your comments. It looks like all I would have to do to communicate with the BIOPAC is to send signals to specific pins on a parallel port cable. I am now grappling with this!

Thanks again!

Hi everyone! I wanted to know if anyone has used Livecode to send signals through a parallel port successfully or to test the functionality of the parallel port. I need to be able to send signals to specific pins on the port, specifically D0, D1, D2, D3, D4, D5, D6, and D7. I have all of the informa...

The BIOPAC scripting interface is within the BIOPAC software itself, not for communication between presentation software and BIOPAC. Thank you for your suggestion though. I need to be able to interface Livecode and BIOPAC from separate computers. I need to be able to have Livecode send a message to ...

Hello everyone,

I wanted to know whether LIVECODE has the ability to interface with the BIOPAC system for recording skin conductance responses. If anyone knows anything, or knows where I can look for resources, please let me know.

Thanks!

I tried to put the buttons on a different card and I am still experiencing an issue. Here is the new code: Card 1 This card shows the face In card script on opencard send mouseUp to button "button" [b]put flushEvents("mouseUp") into temp[/b] end opencard In Button "button" on mouseUp set the cursor...

Hi starfirescully , I'm not sure what you want, but You can use a timer to avoid click before n milliseconds. You may have a look at flushevents in LC dictionary Something like that: local sStarTime on opencard put the milliseconds into sStarTime end opencard on mouseUp put the milliseconds into tT...

I think jmburnod was asking where the scripts set the global variable to 1. Comment out the "pass mouseUp" and see if that helps. The enabled state of the button, or having it covered by another object, won't stop commands that are sent directly to the object's script. Those properties only block m...

I was trying to toggle the buttons on and off so that the error wouldn't occur.

Hello all. I am experiencing an issue with part of the program I have created. This program displays 4 faces randomly one at a time 30 times each. In between the presentation of each face, participants are asked to press a button to indicate the first letter of the name belonging to the face. Here i...

Now I just have to figure out how to make sure only the specific keys work, and no others.

Thanks!

Craig,

That makes sense! I managed to fix the issue. This originally didn't work because I had the "waiting" within a repeat loop, so it didn't actually wait.

Thanks!

I am trying to create a reaction time experiment. Right now I have a button that begins the experiment, coded to display a fixation cross, picture, and word. I have codes that control what each keyDown response does on the card. After the button displays the word, I would like it to wait to continue...

I only found one other instance of this problem and it is unsolved
