Greetings, I spotted an important (typo) error in the SMBus protocol document located at: http://www2.lm-sensors.nu/~lm78/cvs/i2c/doc/smbus-protocol In the SMBus block process call section: SMBus Block Process Call ======================== SMBus Block Process Call was introduced in Revision 2.0 of the specification. This command selects a device register (through the Comm byte), sends 1 to 31 bytes of data to it, and reads 1 to 31 bytes of data in return. S Addr Wr [A] Comm [A] Count [A] Data [A] ... S Addr Rd [A] [Count] A [Data] ... A P It should be a NACK ending the communication, NOT an ack. I checked with the SMBus specs v2.0, p33 fig 5.21. S Addr Wr [A] Comm [A] Count [A] Data [A] ... S Addr Rd [A] [Count] A [Data] ... NA P This error can lead some to error, like it did for me Thank you and best regards. -- Jehan Snyers d'Attenhoven Project Leader Cherokee Europe http://www.cherokee.be/ <http://www.cherokee.be/> Phone: +32.10.438.394 Mobile: +32.478.457.490 *** This message is printed on 100% recyclable electrons. *** -------------- next part -------------- An HTML attachment was scrubbed...
