Hi Ben, > ~ # i2cdump 0 0x4c > (...) > 30: 7f 7f 7f 7f 7f 24 24 24 7f 7f 7f 7f 7f 7f 7f 7f Hm, this is becoming even weirder. Same ID as the LM83 (which doesn't match the datasheet...), and additionally register 0x35 reads 0x24, which means D1 and D3 open on the LM83, while this register is supposedly 0 on the LM82. This also corroborates the 127 degrees C you report for temp2 and temp4, which is the documented LM83's behavior when no diode is connected, while the LM82 datasheet suggests 0 for these registers. So I start wondering... are you *absolutely certain* that what you have is an LM82 and NOT an LM83? -- Jean Delvare
