tadpolectl
—
get or set tadpole microcontroller state
tadpolectl |
[-n ] -w
name=value ... |
The 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 -a
flag can be used to list all the
currently available string or integer values.
The -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:
set mains=`tadpolectl -n hw.power.mains`
If just a MIB style name is given, the corresponding value is
retrieved. If a value is to be set, the -w
flag must
be specified and the MIB name followed by an equal sign and the new value to
be used.
The information available from 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
“0”.
The changeable column indicates whether a process with appropriate
privilege can change the value, and if a displayed value is valid.

For example, to retrieve the current internal battery charge level, one would
use the following request:
tadpolectl hw.power.battery.int.chargelevel
To set the speaker beep frequency of the system to 1000, one would
use the following request:
tadpolectl -w hw.speaker.freq=1000
