 		 #122121 - SiLabs
Responding to: ???'s previous message
hi,

Erik Malund said:
When you get the dats, I hope the CRC can be done by table lookup, otherwise you need HORSEPOWER (e.g. SILabs f12x)


Here is not about OP exactly, anyway just as information: new SiLabs derivatves C8051F41x have Cyclic Redundancy Check Unit built-in hardware. Two polynomials are available: 0x1021 (16-bit) and 0x04C11DB7 (32-bit).

Regards,
Oleg

      I searched all their site            01/01/70 00:00      
         did you search the pascal code examples            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

               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
