diag_eeprom_crc16.h File Reference

This file contains prototypes for APIs to calculate, store and validate 16-bit CCITT CRC for a given EEPROM region.

Includes

Table 1. diag_crc_status_tDIAG_EEPROM_CalculateStoreCRC16 (uint16_t startAddress, uint16_t length, uint16_t storeAddress).

Parameters

[in] startAddress	uint16_t - starting address of EEPROM memory region to be considered for CRC
[in] length	uint16_t - number of bytes from startAddress to be considered for CRC
[in] storeAddress	uint16_t - the EEPROM address where calculated CRC will be stored

Returns

diag_crc_status_t

CRC_OK, CRC_ERROR, CRC_INVALID_ADDRESS, CRC_INVALID_LENGTH

Table 2. diag_crc_status_tDIAG_EEPROM_ValidateCRC16 (uint16_t startAddress, uint16_t length, uint16_t refAddress).

Parameters

[in] startAddress	uint16_t - starting address of EEPROM memory region to be considered for CRC
[in] length	uint16_t - number of bytes from startAddress to be considered for CRC
[in] refAddress	uint16_t - the EEPROM address where reference CRC is available

Returns

diag_crc_status_t

CRC_OK, CRC_ERROR, CRC_INVALID_ADDRESS, CRC_INVALID_LENGTH
