Can the following program using java to write about ~

unsigned short CRC16 (void * Buff_addr, unsigned short len)
{
unsigned char * dataPtr = (unsigned char *) Buff_addr;
unsigned short index = 0;
unsigned short crc = 0;

while (len -)
{
crc = (unsigned char) (crc >> 8) | (crc << 8);
crc ^ = dataPtr [index + +];
crc ^ = (unsigned char) (crc & 0xff) >> 4;
crc ^ = (crc << 8) << 4;
crc ^ = ((crc & 0xff) << 4) << 1;
}

return crc;
}

best you can have a simple test can be run in eclipse below ~
------ Solution ---------------------- ----------------------
try this with c and java ran out the same results

java in short max 32767 , only with int it.

  public class Test01 {
  
  	public static void main(String[] args) {
  		int crc = CRC16(new byte[] { 0x01, 0x02, 0x03, 0x04, 0x03, 0x02 }, 6);
  		System.out.println(Integer.toHexString(crc));
  	}
  
  	static int CRC16(byte[] buffer, int len) {
  		int index = 0;
  		int crc = 0;
  		while (len-- > 0) {
  			crc = (crc >> 8) | (crc << 8);
  			crc ^= buffer[index++];
  			crc ^= (crc & 0xff) >> 4;
  			crc ^= (crc << 8) << 4;
  			crc ^= ((crc & 0xff) << 4) << 1;
  			crc &= 0xFFFF;
  		}
  		return crc;
  	}
  }
