Hi everybody.

Is it possible to measure execution time of program when I debug the program by using of hardware debugger ST-LINK V/2? I use uVision 4 studio (lite version) by KEIL and discovery board for STM32f0 with built in ST-LINK debugger.

Thanks. Martin.

The F0 implementation doesn't have a core cycle counter.

Set up one of the timers, and read the CNT register at stopwatch points, should be able to deal with code up to 65535 cycles.
