Version

v1.6.0

Prefix

MXM

This module supports the calculation of a CRC8 based on the polynomial described in the Maxim data sheets. The polynomial is 0xA6.

Definition in file mxm_crc8.h.

Function Documentation

MXM_CRC8()

uint8_t MXM_CRC8	(	uint16_t *	pData,
		int32_t	lenData
	)

Compute CRC8 with initial value set to 0x00.

Computes the CRC8 for the given data with the given length with the polynomial 0xA6. This function calls MXM_CRC8WithInitValue() with CRC set to 0x00. The result should be 0x00 if you include the CRC into the datastream.

Parameters

[in]	pData	array-pointer with data to be cyclic redundancy checked
[in]	lenData	length of array

Returns

uint8_t containing the computed CRC

MXM_CRC8SelfTest()

STD_RETURN_TYPE_e GEN_MUST_CHECK_RETURN MXM_CRC8SelfTest

(

void

)

Test the CRC8-algorithm with a known pattern.

Tests the CRC8-algorithm with known patterns and asserts that the implementation matches the required algorithm.

Returns

STD_OK if the selfcheck is successful and STD_NOT_OK otherwise
