Dear users,
In my code, the ‘TOO SLOW’ message should show up if there is no key hit until 800ms in a trial lasting for 1500 ms. In my code below (the lines 185 - 191 are the important ones), the message shows up after 800 ms, but blinks weirdly, as well as its shows up even if a key was hit. Can you help me?
