Function Documentation

uint64_t time64_now

(

void

)

Get the current wall time in microseconds.

On POSIX systems this is merely a wrapper around clock_gettime() but is often less cumbersome to work with.

Definition at line 48 of file time_libopencm3.c.

void time_init

(

void

)

Initialize the time sub-system.

uint32_t time_now

(

void

)

Get the current wall time in microseconds and modulo 2^32.

The output of this function will wrap after slightly more than one hour. There this function is only particularly useful for measuring small intervals on small micro-controller systems where 64-bit arithmetic might be regarded as expensive (either in cycles or memory use).
