Hi,
Software Environment:
Matlab: R2022a
Psychophysics Toolbox: 3.0.19.13
I am using KbQueueCreate and other associated functions. I have also used KbQueueRelease function before creating any instance of KbQueueCreate function. I have also provided keyboardID along with all the functions. However, when I am pressing the “space” button, the KbQueueCheck function is returning 0. In fact, no matter what button I press, I always get 0 in return. Basically, it means no key has been pressed.
I have also run the keyboard detection program. It is detecting the keyboard. Output of the key detection program is as follows:
