16 Bit Checksum Calculator
I'm trying to use a PHP CRC16 CCITT function to calculate the checksum.A device sends me a PACKET with Checksum included:10 00 00 00 00 00 00 00 12 51 09 08 00 18 00 04 02 14 00 0c 00 0c 021c 00 02 00 00 00 00 00 00 a0 77The checksum is at the end: a0 77I've tried usingWith no success, the CRC 16 Calculations return: E6 F4 instead of a0 77I get the correct Hex information returned, when I lookup:040214000c000c0000000000on the website but I cannot reproduce it. (make sure to select the input type to HEX)Can you please help me figure out how to get the crc16 CCITT of the string of hex values040214000c000c0000000000I'm looking for the checksum a0 77.
