 		 #122185 - Initial value?
Responding to: ???'s previous message
Mahmood Elnasser said:
I tried the standard polynomial 0x15 = (x+1)(x4 + x3 + 1) and the usb polynomial 0x12 = (x5 + x2 + 1) with no success.

As well as the right polynomial, you also need the correct initial value; eg, all zeros or all ones...

5 bit CRC polynomial            01/01/70 00:00      
   there are several            01/01/70 00:00      
   what does "no success" mean?            01/01/70 00:00

            Yes this is what we were doing            01/01/70 00:00      
   can you find it in the pascal here? -- Kai            01/01/70 00:00

      I searched all their site            01/01/70 00:00      
         did you search the pascal code examples            01/01/70 00:00      
            Where?            01/01/70 00:00      
               I did not look at it all, but there is much here            01/01/70 00:00      
                  I downloaded them all            01/01/70 00:00      
                     what about all the .pas            01/01/70 00:00      
      Found a document name            01/01/70 00:00

               have you seen this?            01/01/70 00:00      
                  Maybe it is X^5+X^4+X^3+X^2+X+1            01/01/70 00:00
