Detailed Description

Defines the interface for reading and writing any data to the NVRAM.

Macro Definition Documentation

#define WICED_NVRAM_VSID_START   0x200

Defines the first usable NVRAM Volatile Section Identifier.

Application can use the VS ids starting from WICED_NVRAM_VSID_START.to WICED_NVRAM_VSID_END Note: Values less than 0x200 reserved for AIROC internal purpose and not advisable to use by applications

Function Documentation

void wiced_hal_delete_nvram	(	uint16_t	vs_id,
		wiced_result_t *	p_status
	)

deletes data from NVRAM at specified VS id

Parameters

[in]	vs_id	: Volatile Section Identifier. Application can use the VS ids from WICED_NVRAM_VSID_START to WICED_NVRAM_VSID_END
[out]	p_status	: Pointer to location where status of the call is returned

Returns

void

uint16_t wiced_hal_read_nvram	(	uint16_t	vs_id,
		uint16_t	data_length,
		uint8_t *	p_data,
		wiced_result_t *	p_status
	)

Reads the data from NVRAM.

Parameters

[in]	vs_id	: Volatile Section Identifier. Application can use the VS ids from WICED_NVRAM_VSID_START to WICED_NVRAM_VSID_END
[in]	data_length	: Length of the data to be read from NVRAM
[out]	p_data	: Pointer to the buffer to which data will be copied
[out]	p_status	: Pointer to location where status of the call is returned

Returns

the number of bytes read, 0 on failure

uint16_t wiced_hal_write_nvram	(	uint16_t	vs_id,
		uint16_t	data_length,
		uint8_t *	p_data,
		wiced_result_t *	p_status
	)

Writes the data to NVRAM, Application can write up to 255 bytes in one VS id section.

Parameters

[in]	vs_id	: Volatile Section Identifier. Application can use the VS ids from WICED_NVRAM_VSID_START to WICED_NVRAM_VSID_END
[in]	data_length	: Length of the data to be written to the NVRAM,
[in]	p_data	: Pointer to the data to be written to the NVRAM
[out]	p_status	: Pointer to location where status of the call is returned

Returns

number of bytes written, 0 on error
