WebA global variable to the module to specify the CPU clock frequency (elapsed_CPU_clock_frequency) which can be used to convert from cycles to microseconds. You would simply need to divide the different fields (.current, .min and .max) by elapsed_CPU_clock_frequency in the elapsed_time_stop() Make sure you initialize this … WebSorted by: 382.
