ADM1026HM(4)                 Device Drivers Manual                ADM1026HM(4)

NAME
     adm1026hm - Analog Devices ADM1026 complete thermal system management
     controller

SYNOPSIS
     adm1026hm* at iic0 addr 0x2e: ADM1026 hardware monitor: rev. 0x4, step.
     0x5
     adm1026hm*: 8 fans, 3 temperatures, 15 voltages

DESCRIPTION
     The adm1026hm driver provides support for the Analog Devices ADM1026
     hardware monitor.  The chip possesses 8 fan speed sensors, 3 temperature
     sensors, and 17 voltage sensors.  The number of each sensor type
     configured by the driver depends on the chip configuration.

     The values of the sensors are made available through the envstat(8)
     interface.

AUTHORS
     The adm1026hm driver was written by Julian Coleman <jcoleman@NetBSD.org>.

BUGS
     It's not possible to determine if either a sensor is not connected, or
     the monitored device is producing no output.  Therefore, unconnected
     sensors will show outputs of 0.

     The adm1026hm driver does not support checking or altering limit values,
     interrupt output, nor the built-in EEPROM.
