CRC32 Functions
-
void
csp_crc32_gentab(void)¶ Generate precomputed CRC32 table.
-
int
csp_crc32_append(csp_packet_t *packet, bool include_header)¶ Append CRC32 checksum to packet.
- Return
- 0 on success, -1 on error
- Parameters
packet: Packet to append checksuminclude_header: use header in calculation (this will not modify the flags field)
-
int
csp_crc32_verify(csp_packet_t *packet, bool include_header)¶ Verify CRC32 checksum on packet.
- Return
- 0 if checksum is valid, -1 otherwise
- Parameters
packet: Packet to verifyinclude_header: use header in calculation (this will not modify the flags field)
-
uint32_t
csp_crc32_memory(const uint8_t *data, uint32_t length)¶ Calculate checksum for a given memory area.
- Return
- return uint32_t checksum
- Parameters
data: pointer to memorylength: length of memory to do checksum on
