My documentation states that the full range of adjustment is: 7f ff ff ff => +383 Hz 80 00 00 00 => -383 Hz
This scale factor is clearly wrong - using it and applying an appropriate correction changes the frequency way too much.
From: http://article.gmane.org/gmane.comp.time.nuts/9473/match=fe+5680+pin+outs (thanks Jose!) a better estimate is 140000 / Hz. Using data after 20 hours: http://www.c-c-i.com/node/155the estimated frequency offset is 1.36E-3 Hz. Using the above scale factor gives a correction of -190 counts. Here is the command I used to (temporarily) program the new offset:
2e 09 00 27 ff ff ff 42 bd (the bd is the exclusive-or checksum of the offset) Now I wait ... -- Bob Smither, PhD Circuit Concepts, Inc. ========================================================================= A government which robs Peter to pay Paul can always depend on the support of Paul. --George Bernard Shaw ========================================================================= smit...@c-c-i.com http://www.C-C-I.Com 281-331-2744(office) -4616(fax)
