- Hi everyone.
-
- I need to have an interrupt at shorter intervals than the timer
- chip is programmed to do.
-
- "Undocumented Windows" explains how to set a synchronous callback.
-
- From what I know at this points it seems I need a timer device driver
- that will reprogram the timer chip with the frequency I want.
-
- The multimedia extensions available with 3.1 are supposed to do this for
- me. Yes ?
-
- I am hesitant to manually reprogram the chip because I dont know how this would
- fare with the rest of windows. Unexplained crashes are the least thing I want.
-
- Has anyone done anything similar ?
-
- Thanks
- NN
