Function Documentation

void pal_alert

(

void

)

Alert indication.

This Function can be used by any application to indicate an error condition. The function is blocking and does never return.

Definition at line 191 of file pal.c.

References ALERT_INDICATE, ALERT_INIT, and pal_timer_delay().

retval_t pal_init

(

void

)

Initialization of PAL.

This function initializes the PAL. The RC oscillator is calibrated.

Returns:

MAC_SUCCESS if PAL initialization is successful, FAILURE otherwise

Definition at line 50 of file pal.c.

References gpio_init(), MAC_SUCCESS, mcu_init(), timer_init(), and wdt_init().

retval_t pal_ps_get	(	ps_type_t	ps_type,
		uint16_t	start_addr,
		uint16_t	length,
		void *	value
	)

Get data from persistence storage.

Parameters:

[in]	ps_type	Persistence storage type
[in]	start_addr	Start offset within EEPROM
[in]	length	Number of bytes to read from EEPROM
[out]	value	Data from persistence storage

Returns:

MAC_SUCCESS if everything went OK else FAILURE

Definition at line 110 of file pal.c.

retval_t pal_ps_set	(	uint16_t	start_addr,
		uint16_t	length,
		void *	value
	)

Write data to persistence storage.

Parameters:

[in]	start_addr	Start address offset within EEPROM
[in]	length	Number of bytes to be written to EEPROM
[in]	value	Data to persistence storage

Returns:

MAC_SUCCESS if everything went OK else FAILURE

Definition at line 157 of file pal.c.

References FAILURE, and MAC_SUCCESS.

void pal_task

(

void

)

Services timer and sio handler.

This function calls sio & timer handling functions.

Definition at line 79 of file pal.c.
