Nd get or set tadpole microcontroller state
Sh SYNOPSIS
Nm tadpolectl

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
