|
|
.Sh SYNOPSIS

|
.Cd "lmenv0 at iic0 addr 0x2c: ADM9240 rev 2"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the
|
|
.Tn National Semiconductor
|
|
LM87,
|
|
.Tn National Semiconductor
|
|
LM81,
|
|
.Tn Analog Devices
|
|
ADM9240, and
|
|
.Tn Dallas Semiconductor
|
|
DS1780 iicbus hardware monitors.
|
|
Sensor values are reported through the
|
|
.Xr envstat 8
|
|
interface.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
supports the following voltage, temperature, and fan speed sensors:
|
|
.Bl -column "+5Vin/Vcc" "Temperature" -offset indent
|
|
.It Sy "Sensor" Ta "Type"
|
|
.It Li "+2.5Vin" Ta "Volts DC"
|
|
.It Li "Vccp1" Ta "Volts DC"
|
|
.It Li "+Vcc" Ta "Volts DC"
|
|
.It Li "+5Vin/Vcc" Ta "Volts DC"
|
|
.It Li "+12Vin" Ta "Volts DC"
|
|
.It Li "Vccp2" Ta "Volts DC"
|
|
.It Li "External" Ta "Temperature"
|
|
.It Li "Internal" Ta "Temperature"
|
|
.It Li "FAN1" Ta "Speed"
|
|
.It Li "FAN2" Ta "Speed"
|
|
.El
|
|
On the LM87 monitor, AIN1 and AIN2 Volts DC sensors may replace either,
|
|
or both of the FAN1 and FAN2 speed sensors, respectively.
