• HAL Init
• PARA_Init
• Error_Init
• SystemMessage_Init
• PARA_Backup_Init

PARA_FlashReadFromBackup()

void PARA_FlashReadFromBackup	(	uint16_t	location,
		ParameterAccessSource	Access,
		uint8_t	AccessLevel
	)

Reads backup-values from flash and stores them into parameter values.

All parameters with storage-location selected in parameter location are processed, all others are ignored. The parameter values are written with the OnWrite-function defined in the parameter itself. In case of an error, the default value is set.

Parameters

location	selects the storage location
Access	Source of access (see Access restrictions).
AccessLevel	Actual AccessLevel (see Access restrictions).

All parameters with storage-location selected in parameter location are processed, all others are ignored. The parameter values are written with the OnWrite-function defined in the parameter itself. In case of an error, the default value is set. Flash must be unlocked!

Parameters

location	selects the storage location
Access	Source of access (see Access restrictions).
AccessLevel	Actual AccessLevel (see Access restrictions).

PARA_FlashRestoreDefaults()

bool PARA_FlashRestoreDefaults	(	uint16_t	location,
		ParameterAccessSource	Access,
		uint8_t	AccessLevel
	)

PARA_FlashWriteToBackup()

bool PARA_FlashWriteToBackup

(

uint16_t

location

)

Writes backup-values into flash All parameters with storage-location selected in parameter location are processed, all others are ignored.

Parameters

location

selects the storage location

Return values

True	if successfull.
