Hi All, working on some software to interface via a serial port protocol which requires CRC16. This is using a non-pic micro that has a CRC16 generator on board.. but it gives a different result than a known good CRC value... Is there different standards for CRC16 calculations? How is CRC16 generally calculated on a string of data? Thanks! Regards Peter Mcalpine -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
