Hi Andrea,
excellent - that matches the output I get. Now all we have to do is to
match the values
to actual voltages. in2 and in3 match the 3.3V seen in the BIOS, but for
the others
I have no idea.
As for the other chips in this family, in2, in3, in7 and in8 are
internal voltages so their mapping and scaling is fixed. The pin names
also strongly suggest connecting Vcore to in0, and I've never seen a
board manufacturer diverge from this. So you can start with the
following config statements:
chip "nct6775-*" "nct66776-*"
label in0 "Vcore"
label in2 "AVCC"
label in3 "+3.3V"
label in7 "3VSB"
label in8 "Vbat"
set in2_min 3.3 * 0.90
set in2_max 3.3 * 1.10
set in3_min 3.3 * 0.90
set in3_max 3.3 * 1.10
set in7_min 3.3 * 0.90
set in7_max 3.3 * 1.10
set in8_min 3.0 * 0.90
set in8_max 3.0 * 1.10
This leaves only 4 voltage inputs to configure, presumably for +5V,
+12V, and possibly 5VSB and Vdimm. Check the labels and values in the
BIOS (write them all down if they fluctuate) and maybe we can figure it
out.

OK Here's the infomation
nct6776-isa-0290
Adapter: ISA adapter
Vcore: +1.18 V (min = +0.00 V, max = +1.74 V)
in1: +1.02 V (min = +0.00 V, max = +0.00 V) ALARM
AVCC: +3.36 V (min = +2.98 V, max = +3.63 V)
+3.3V: +3.34 V (min = +2.98 V, max = +3.63 V)
in4: +1.03 V (min = +0.00 V, max = +0.00 V) ALARM
in5: +2.04 V (min = +0.00 V, max = +0.00 V) ALARM
in6: +0.78 V (min = +0.00 V, max = +0.00 V) ALARM
3VSB: +3.42 V (min = +2.98 V, max = +3.63 V)
Vbat: +3.30 V (min = +2.70 V, max = +3.30 V) ALARM
fan1: 550 RPM (min = 0 RPM) ALARM
fan2: 1013 RPM (min = 0 RPM) ALARM
fan3: 0 RPM (min = 0 RPM) ALARM
fan4: 824 RPM (min = 0 RPM) ALARM
fan5: 0 RPM (min = 0 RPM) ALARM
temp1: +24.0°C (high = +0.0°C, hyst = +0.0°C) ALARM sensor =
thermistor
temp2: -60.0°C (high = +80.0°C, hyst = +75.0°C) sensor = diode
temp3: +38.0°C (high = +80.0°C, hyst = +75.0°C) sensor =
thermistor
cpu0_vid: +2.050 V
and BIOS
CPU temp 43
MB temp 25
CPU Volt 1.114-1.1176
3.3Volt 3.36 - 3.34
5Volt 5.160
12Volt 12.288
So it looks as if in4 * 5 is 5Volt, in5 * 6 is 12volt. This is on a asus
p8p67 pro, but I've seen the same values on a asus p8p67 delux.
Looking in the n6776f specification if looks as if AUXTIN(temp3) and in6
share the same pin (pin 109) so we can't have both enabled.

Ian Dobson

also pwm output won't work, Bank 0 index 1 is the actual value used for the
pwm output, while the setpoint for the pwm value is in Bank1,index09
bit[7:0] (this is only used in manual mode)
so in the code we could do something like
static const u8 N677X_REG_PWM_ACTUAL[] = { 0x01, 0x03, 0x11 };
static const u16 N677X_REG_PWM_SETPOINT[] = { 0x109, 0x209, 0x309 };
in update_device we always read from _ACTUAL, and in store_pwm if the chip
is a n677x write to _SETPOINT.
If you want I can try and write a patch.

Ian Dobson
