Jean, Here's the i2cdump output. I did not run sensors-detect on my target, as perl isn't installed. Ben ~ # i2cdump 0 0x4c No size specified (using byte-data access) WARNING! This program can confuse your I2C bus, cause data loss and worse! I will probe file /dev/i2c/0, address 0x4c, mode byte Continue?

Wow, i2cdump runs MUCH faster with those timing changes! -----Original Message----- From: Jean Delvare [mailto:khali at linux-fr.org] Sent: Friday, June 10, 2005 2:13 AM To: Gardner, Ben Cc: LM Sensors Subject: RE: How can I skip i2c detection? Hi Ben, > Good point about the 127. > Perhaps there isn't a reliable way to distinguish the two chips. =( Does sensors-detect find an LM82, or an LM83? Or both? Or none? Could you please provide a dump of your LM82 chip (use i2cdump)? I could compare with my LM83. If there really is no way to differenciate between both chips, well, we'll simply document that fact, and invite LM82 owners to ignore the two irrelevant temperature channels. Thanks, -- Jean Delvare
