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.h.

Function Documentation

◆ get_sys_time_msec()

uint32_t get_sys_time_msec ( void )

Get the time in milliseconds since startup.

Returns: milliseconds since startup as uint32_t

Definition at line 98 of file sys_time_arch.c.

◆ get_sys_time_usec()

uint32_t get_sys_time_usec ( void )

Get the time in microseconds since startup.

WARNING: overflows after 70min!

Returns: microseconds since startup as uint32_t

WARNING: overflows after 71min34seconds!

Returns: current system time as uint32_t

Definition at line 71 of file sys_time_arch.c.

◆ get_sys_time_usec100()

uint32_t get_sys_time_usec100 ( void )

Get the time in microseconds divided by 100 since startup.

WARNING: overflows after 7000min!

Returns: 100microseconds since startup as uint32_t

Get the time in microseconds divided by 100 since startup.

WARNING: overflows after 7000 minutes!

Returns: current system time as uint32_t

Definition at line 87 of file sys_time_arch.c.

◆ sys_time_msleep()

void sys_time_msleep ( uint16_t ms )

Definition at line 128 of file sys_time_arch.c.

◆ sys_time_ssleep()

void sys_time_ssleep ( uint8_t s )

Definition at line 133 of file sys_time_arch.c.

References s.

◆ sys_time_usleep()

void sys_time_usleep ( uint32_t us )

sys_time_usleep(uint32_t us)

using intermediate 64 bits variable to avoid wrapping

max sleep time is around 10 days (2^32 / CH_CFG_ST_FREQUENCY) at 10kHz

Definition at line 116 of file sys_time_arch.c.
