.Sh DESCRIPTION
|
|
The
|
|
.Nm tadpolectl
|
|
utility retrieves values from the ts102 microcontroller
|
|
and allows processes with appropriate privilege to set some values.
|
|
The state to be retrieved or set is described using a
|
|
``Management Information Base'' (``MIB'') style name,
|
|
described as a dotted set of components.
|
|
The
|
|
.Fl a
|
|
flag can be used to list all the currently available string or integer values.
|
|
.Pp
|
|
The
|
|
.Fl n
|
|
flag specifies that the printing of the field name should be
|
|
suppressed and that only its value should be output.
|
|
This flag is useful for setting shell variables.
|
|
For example, to save the mains power status in variable mains, use:
|
|
.Bd -literal -offset indent -compact
|
|
set mains=`tadpolectl -n hw.power.mains`
|
|
.Ed
|
|
.Pp
|
|
If just a MIB style name is given,
|
|
the corresponding value is retrieved.
|
|
If a value is to be set, the
|
|
.Fl w
|
|
flag must be specified and the MIB name followed
|
|
by an equal sign and the new value to be used.
|
|
.Pp
|
|
The information available from
|
|
.Nm tadpolectl
|
|
consists of only integers. Some registers can be modified, but have no
|
|
way of reading what the current value is. Those registers will always
|
|
display
|
|
.Dq 0 .
|
|
.Pp
|
|
The changeable column indicates whether a process with appropriate
|
|
privilege can change the value, and if a displayed value is valid.

.Sh EXAMPLES
|
|
For example, to retrieve the current internal battery charge level,
|
|
one would use the following request:
|
|
.Bd -literal -offset indent -compact
|
|
tadpolectl hw.power.battery.int.chargelevel
|
|
.Ed
|
|
.Pp
|
|
To set the speaker beep frequency of
|
|
the system to 1000, one would use the following request:
|
|
.Bd -literal -offset indent -compact
|
|
tadpolectl -w hw.speaker.freq=1000
