CRC16

CRC16
Enter databytes and data count. The checksum will be retuened as a byte  
- BYTE Data
 
- BYTE DataLength
Actual Data length is only required if using Final XOR Value greater than 0. If not then Data length can be 0 
- UINT Return


CRC16_Array

CRC16_Array
Enter databytes and data count. The checksum will be retuened as an unsigned integer 
- BYTE Data
 
- BYTE DataLength
Max data lenght (2 - 20) 
- UINT Return


CRC8

CRC8
Enter databytes and data count. The checksum will be retuened as a byte  
- BYTE Data
 
- BYTE DataLength
Actual Data length is only required if using Final XOR Value greater than 0. If not then Data length can be 0 
- BYTE Return


CRC8_Array

CRC8_Array
Enter databytes and data count. The checksum will be retuened as a byte  
- BYTE Data
 
- BYTE DataLength
Max data length (2 - 20) 
- BYTE Return


ClearChecksumValue

ClearChecksumValue
 
- VOID Return


compareChecksum

compareChecksum
Compare generated checksum uisng CRC8 or CRC16 macros. 0 = match, 1 = don't match 
- UINT Checksum
 
- BOOL Return
