2. You can overload a number of methods to cover various cases of parameters you might want to pass to the lambda: public static Stopwatch MeasureTime<T>(int iterations, Action<T> action, T param) {. var sw = new Stopwatch(); sw.Start(); for (int i = 0; i < iterations; i++) {. action.Invoke(param);
Dec 11, 2014 · start should probably set endTime to -1. getElapsedTime should be an instance method, not take arguments, return long and return endTime - startTime. to see it work, in your main, create a stopwatch, start the timer, call Thread.sleep (sometime), call stop, print out getElapsed. answered Dec 11, 2014 at 16:45.

Dec 9, 2017 · I have to write a stopwatch class in c++. The way I am trying to do this is by defining a variable to save laps (named 'time') and a bool that I use to see if the watch is started or stopped. When entering a char the timer should start and set time1. When another char is entered the bool switches to false and sets time2 and then prints time2 ...

Jul 12, 2023 · Note: I added a delay method as well. You can verify stopwatch_delay by calling STOPWATCH_START, run stopwatch_delay(ticks), then call STOPWATCH_STOP and verify with CalcNanosecondsFromStopwatch(m_nStart, m_nStop). Adjust ticks as needed.
Feb 2, 2018 · It uses the STM32's DWT_CYCCNT register, which is specifically designed to count actual clock ticks, located at address 0xE0001004. To verify the delay accuracy (see main), you can call STOPWATCH_START, run stopwatch_delay(ticks), then call STOPWATCH_STOP and verify with CalcNanosecondsFromStopwatch(m_nStart, m_nStop). Adjust ticks as needed.
Nov 9, 2008 · The time taken for such an action is in the space of nanoseconds. As the API is a C++ class/function, I am using the timer.h to calculate the same: #include <ctime>. #include <iostream>. using namespace std; int main(int argc, char** argv) {. clock_t start; double diff; start = clock();
Nov 23, 2014 · The macros STOPWATCH_START; and STOPWATCH_STOP; are causing "illegal indirection" errors from my compiler. The double pointer reference is causing the counter value read to be used as a pointer. #define STOPWATCH_START { m_nStart = *(*(volatile unsigned int*)0xE0001004);} #define STOPWATCH_STOP { m_nStop = *(*(volatile unsigned int *)0xE0001004);}
System.Diagnostics.StopWatch is the typical method for tracking this sort of thing. If you are using VS and are just trying to do performance checks, you could also profile the code while will give you a good idea of how much time is spent in each method.
