First, you need to find the preprocessor define for CCITT_POLY. The code is incomplete without it.
Second, where did this code come from? It defines an unused local named cval, which will usually cause at least a compilation warning. This looks like a snippet, not a complete CCITT CRC calculation. -- Sincerely, Chris Calloway http://www.seacoos.org office: 332 Chapman Hall phone: (919) 962-4323 mail: Campus Box #3300, UNC-CH, Chapel Hill, NC 27599 Johan Geldenhuys wrote: > Hi all, > > I'm not a C++ expert at all and I would like to find out if somebody can > explain to me how the statement below can be done in Python? > > """ > _uint16 ComCRC16(_uint8 val, _uint16 crc) > { > _uint8 i; > _uint16 cval; > > for (i=0;i<8;i++) > { > if (((crc & 0x0001)^(val & 0x0001))!= 0) crc = (crc >> 1)^ > CCITT_POLY; > else crc >>= 1; > val >>= 1; > } > return crc > } > > """ _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
