Hello,
I use the Eyelink 1000 and the PTB for an experiment which includes several trials. At the begining of each trial I am doing a drift correction by calling
>> EyelinkDoDriftCorrection(el);
My problem is : every time I call this function, the setup screen with the instructions blinks (!!!) just before displaying the calibration target. After debugging I found out this is the function "PsychEyelinkDispatchCallback(callArgs, msg)" which displays the setup screen with callArgs = [7,0,0..] at that time, but I have no idea why this callback get those arguments at that point.
I tried to call EyelinkDoDriftCorrection(el, x, y, draw, allowsetup) with allowsetp = 0 but it didn't solve this issue..
Thanks for your help !
