Variable Documentation
SingletonPtr< PlatformMutex > mbed_crc_mutex |
CRC object provides CRC generation through hardware/software.
ROM polynomial tables for supported polynomials (:: crc_polynomial_t) will be used for software CRC computation, if ROM tables are not available then CRC is computed runtime bit by bit for all data input.
- Note:
- Synchronization level: Thread safe
- Template Parameters:
-
polynomial CRC polynomial value in hex width CRC polynomial width
Example: Compute CRC data
#include "mbed.h" int main() { MbedCRC<POLY_32BIT_ANSI, 32> ct; char test[] = "123456789"; uint32_t crc = 0; printf("\nPolynomial = 0x%lx Width = %d \n", ct.get_polynomial(), ct.get_width()); ct.compute((void *)test, strlen((const char*)test), &crc); printf("The CRC of data \"123456789\" is : 0x%lx\n", crc); return 0; }
Example: Compute CRC with data available in parts
#include "mbed.h" int main() { MbedCRC<POLY_32BIT_ANSI, 32> ct; char test[] = "123456789"; uint32_t crc = 0; printf("\nPolynomial = 0x%lx Width = %d \n", ct.get_polynomial(), ct.get_width()); ct.compute_partial_start(&crc); ct.compute_partial((void *)&test, 4, &crc); ct.compute_partial((void *)&test[4], 5, &crc); ct.compute_partial_stop(&crc); printf("The CRC of data \"123456789\" is : 0x%lx\n", crc); return 0; }
