I am trying to get an output pulse of 100Hz and 5V form USB-6501.
The maximum I am getting is 10Hz.
I changed the output of a pin in a continuous for loop from 0 to 5v (without any delays) and the maximum freq I get is 10Hz.
I tried precise timming by using the timer function and I toggeled the output pin after every 0.001 sec and still the output was 10Hz. Even if I decrease the time period for the timer fcn still I dont get above 10.5Hz.
