NAME

digitemp - program to read from temperature sensors.

SYNOPSIS

digitemp [options]

DESCRIPTION

DigiTemp uses the Dallas 1-wire bus to read temperatures from digital sensors attached to a serial port adapter. It handles initializing the bus, searching for attached devices, reading devices and custom log strings. It suports the following temperature devices: DS1820, DS18S20, DS18B20, DS1822

It also handles the DS2406 1-wire hub switches, and DS2422 and DS2423 counters.

DigiTemp uses either the DS9097 passive serial port adapter, or the DS2480B based DS9097U adapter (recommended).

-h, -?
Show summary of options.
-v
Show verbose output.
-i
Initialize .digitemprc file, search the bus for all supported devices.
-w
Walk the full device tree and display the serial number and type of all devices detected on the bus.
-s /dev/ttyS0
Set serial port to use. Make sure you have permission to access this port.
-l /var/log/temperature
Send output to logfile, the output format is defined by the .B -o command
-c digitemp.conf
Set digitemp configuration file. The default is .digitemprc in the current directory.
-r 1000

-t #
Read sensor number #, the # depends on the order of the sensors in the
