Using the timer
-
Hi I am controlling an electrical circuit using the computer through the computer ports. I am trying to capture a fast changing analog signal using sampling. So I am just enquiring about the maximum frequency that we could set the timer to using the following function: SetTimer(1, 2000, 0); I actually want the timer to interrupt every ten micro seconds (10uS). Is it possible with this type of timers. If not, can anyone guide me to a timer that is capable of doing so. Thanx in advance

Timers are set in milliseconds and therefore do not have the resolution you require. I suggest that you use another thread to do this work. You could then use the high-resolution performance counters
QueryPerformanceCounter()andQueryPerformanceFrequency()to monitor the time. Ant. I'm hard, yet soft.
I'm coloured, yet clear.

I was suggesting that you uses the performance counter functions in order to write your own high-resolution timer. Ant. I'm hard, yet soft.
