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

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.

Definition at line 117 of file mxm_crc8.c.
STD_RETURN_TYPE_e 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.
