nullfx / swift-nullfx.crc Goto Github PK

Hi,
I'm working on a BLE project where I have to calculate a CRC-8 value.

I have a working example in my Swift app where I have the values [0xAA, 0x14, 0xEB, 0x00, 0x00, 0x00, 0x00] and according to https://crccalc.com/?crc=0xAA 0x14 0xEB 0x00 0x00 0x00 0x00&method=crc8&datatype=hex&outtype=hex the check sum is OxC6

This works in my app as well so I believe its correct.

When I use your library like this:
let val = Crc8.computeChecksum(on: [0xAA, 0x14, 0xEB, 0x00, 0x00, 0x00, 0x00])
var st = String(format:"%02X", val)
st += " is the hexadecimal representation of (val)"
print(st)

I get a value of 75, which in Hex is 4B

Can you please help me understand what I'm doing wrong?

thanks!!
