◆ compute16CCITT()
| uint16_t FW_EXPORT compute16CCITT | ( | const void * | buf, |
| size_t | buf_length | ||
| ) |
This function computes the CRC-8-CCITT (Cyclic Redundancy Check) of a buffer "buf" of "buf_length" bytes.
- Parameters
-
[in] buf The buffer at hand [in] buf_length Number of bytes in "buf"
- Returns
- The calculated CRC
Note that a void pointer is a pointer that has no associated data type with it. A void pointer can hold address of any type and can be typcasted to any type.
◆ isValid()
| bool FW_EXPORT isValid | ( | const void * | block | ) |
