Hi experts, I am a newbie of psychopy. I have made a simple lexical decision experiment with a builder mode and I want to use a cedrus response box instead of a keyboard. Should I use a coder mode to make the cedrus response box work? The model of the box is RB-540. Thanks in advance, Wonil

There is a Cedrus component in Builder. Have you tried that, and if so, what went wrong?

Thanks for your reply, Michael! I’ve actually used the Builder and tried to run the program. But I got this errors. ########### Running: C:\Experiments\BA\psychopy\pilot_test_cedrus.py ########### Traceback (most recent call last): File “C:\Experiments\BA\psychopy\pilot_test_cedrus.py”, line 14,…

This probably refers to the coding of the given value of the button - are you using non-ASCII characters?

Yes, I have to use Korean characters. Do you have any idea to solve this issue? Thanks,

Not sure - depends where the characters are. Psychopy (and indeed Python) have good handling of characters because they use UTF8. If you are importing conditions from an XLSX file, try changing it to a .csv file.

Thanks for your reply. I have actually deleted all non-English characters but still have the same error. Hmm…Is there anyone who has any idea why it is happening? Thanks,

Not without more information about the experiment. The error only refers to a failure to decode a unicode character, so there’s no way to tell from the information you have given. Try giving a brief description of what you are trying to achieve and provide screenshots of any code components you ha…

Also see if this helps: [image] UnicodeDecodeError Coding For a start, perhaps consider liberally sprinting a few print(i, theseKeys[i]) statements around so you can see where any problems arise. I suspect you should probably try and integrate that code into the last sec…

Thanks for your replies. The problems are getting worse. It doesn’t seem to be a problem with fonts or characters. I actually made a very tiny simple program (please see the attached builder view screen) with a builder mode and still had the same problem. Please see the attached files. I made the s…

Try reinstalling psychopy - if it’s working on other computers then something may have gone wrong with the build.
