Hi everyone,
I am currently writing a code using Timer function to record mouse path with 1kHz rate (i.e. I want to record the position of the mouse every 0.001s). I discovered that the Timer function does not have the precision under 50ms. I also found that the matlab time outputs did not add up to the total trial running time (i.e. if I add up the time tracked by the Timer function, the value is always less than the actual running time of the mouse path). I think if the error in timing comes from the accumulation of excution time of the Timer function, in theory the value should be greater than the actual running time. I am hoping if anyone could take a look at my code and give me some suggestion, and am also wondering if people have encountered similar issue. The following is the Timer Function that I used:
timerObj = timer(‘TimerFcn’, @recordMousePos, ‘Period’, 0.001, ‘ExecutionMode’, ‘fixedRate’);

Thank you!Hi everyone,
