8 bit CCITT CRC

[Jan_HeG]

Hi,

I am attempting to generate a 8 bit CCITT CRC with the 9-bit polynomal U8+U4+U3+U2+1

I have studied and attempted to modify the 16-bit CRC calculator found Here and the Vi posted by Shoneill here, but I am getting nowere.. 

CRC generator should be initialized to 0, LSB is sent first. 

In the datasheet I found the example:

Data 1 : 1010 0000

Data 2 : 0000 0011

CRC :     0010 1010

Any assistance to how I can modify the existing 16-bit calcultors, or would it be a better idea to start from scratch?

Solved. Modifying the vi by shoneill did eventually give me the result I needed.

Jan_HeG could you share your code here?

Thanks!
