Detailed Description

Timing related functions.

Function Documentation

sys_current_ms()

uint32_t sys_current_ms

(

)

Get current millisecond.

Returns

Current millisecond

sys_tick_count()

uint32_t sys_tick_count

(

)

Get current tick count.

Returns

Current tick count

Note that system is usually built that one tick corresponds to one millisecond. Thus, sys_current_ms() returns the same value as this function.

sys_timer_active()

int sys_timer_active

(

int

timer_ix

)

Check timer running status.

Parameters

timer_ix

Timer index

Returns

(0/1) 1 - timer is running

sys_timer_disable()

void sys_timer_disable

(

int

timer_ix

)

Disables system timer.

Parameters

timer_ix

Timer index

sys_timer_start()

void sys_timer_start	(	int	timer_ix,
		uint32_t	ms_value
	)

Starts system timer (non-periodic pooling timer)

Parameters

timer_ix	Timer index
ms_value	Timeout value (milliseconds)

sys_timer_timeout()

int sys_timer_timeout

(

int

timer_ix

)

Check for timer timeout.

Returns

(0/1) 1 - timer expired
