Detailed Description

Implementation of system time functions for ChibiOS arch.

Mostly empty functions for Paparazzi compatibility, since ChibiOS uses different system time functions.

Definition in file sys_time_arch.c.

Function Documentation

uint32_t get_sys_time_usec ( void  )

Get the time in microseconds since startup.

WARNING: overflows after 70min!

microseconds since startup as uint32_t
