LibCRC API Reference – crc_8()

crc_8( input_str, num_bytes );


Parameter Type Description
input_str const unsigned char * The input byte buffer for which the CRC must be calculated
num_bytes size_t The number of characters in the input buffer

Return Value

Type Description
uint8_t The resulting CRC value


The function crc_8() calculates a 8 bit CRC value of an input byte buffer based on the CRC algorithm as it is used in Sensirion SHTxx temperature and humidity sensors. The buffer length is provided as a parameter and the resulting CRC is returned as a return value by the function. The size of the buffer is limited to SIZE_MAX.
