Function Documentation

no_os_rtc_get_cnt()

int32_t no_os_rtc_get_cnt	(	struct no_os_rtc_desc *	dev,
		uint32_t *	tmr_cnt
	)

Get the current count for the real time clock.

Parameters

dev	- The RTC descriptor.
tmr_cnt	- Pointer where the read counter will be stored.

Returns

0 in case of success, errno codes otherwise.

no_os_rtc_init()

int32_t no_os_rtc_init	(	struct no_os_rtc_desc **	device,
		struct no_os_rtc_init_param *	init_param
	)

Initialize the RTC peripheral.

Parameters

device	- The RTC descriptor.
init_param	- The structure that contains the RTC initialization.

Returns

0 in case of success, errno codes otherwise.

no_os_rtc_remove()

int32_t no_os_rtc_remove

(

struct no_os_rtc_desc *

dev

)

Free the resources allocated by no_os_rtc_init().

Parameters

dev	- The RTC descriptor.

Returns

0 in case of success, errno codes otherwise.

no_os_rtc_set_cnt()

int32_t no_os_rtc_set_cnt	(	struct no_os_rtc_desc *	dev,
		uint32_t	tmr_cnt
	)

Set the current count for the real time clock.

Parameters

dev	- The RTC descriptor.
tmr_cnt	- New value of the timer counter.

Returns

0 in case of success, errno codes otherwise.

no_os_rtc_set_irq_time()

int32_t no_os_rtc_set_irq_time	(	struct no_os_rtc_desc *	dev,
		uint32_t	irq_time
	)

Set the current count for the real time clock.

Parameters

dev	- The RTC descriptor.
irq_time	- The number of seconds at which the interrupt must occur.

Returns

0

no_os_rtc_start()

int32_t no_os_rtc_start

(

struct no_os_rtc_desc *

dev

)

Start the real time clock.

Parameters

dev	- The RTC descriptor.

Returns

0 in case of success, errno codes otherwise.

Here is the caller graph for this function:

no_os_rtc_stop()

int32_t no_os_rtc_stop

(

struct no_os_rtc_desc *

dev

)

Stop the real time clock.

Parameters

dev	- The RTC descriptor.

Returns

0 in case of success, errno codes otherwise.
