lisa.energy_meter.ACME#

class lisa.energy_meter.ACME(target, channel_map={'CH0': 0}, host='baylibre-acme.local', iio_capture_bin='iio-capture', res_dir=None)[source]#

Bases: EnergyMeter

BayLibre’s ACME board based EnergyMeter

Parameters:

channel_map (collections.abc.Mapping) – Channels to use
host (str) – Hostname or IP address of the ACME board
iio_capture_bin (str) – path to iio-capture binary

Deprecated since version 2.0.

ACME is deprecated and will be removed in version 4.0: LISA energy meters are deprecated, please use devlib instruments or contribute the instrument to devlib

Classes

CONF_CLASS

Configuration class for ACME.

Attributes

`INIT_KWARGS_KEY_MAP`	Dictionary of `__init__` parameter names to configuration key path.
`REPORT_DELAY_S`	iio-capture returns an empty string if killed right after its invocation, so we have to enforce a delay between reset() and report().
`name`

Properties

logger ^inherited

Convenience short-hand for self.get_logger().

Methods

`report()`	Stop iio-capture and collect sampled data.
`reset()`	Reset energy meter and start sampling from channels specified in the target configuration.
`sample()`	Get a sample from the energy meter.
`check_init_param()` ^inherited	Take the same parameters as `__init__`, and check their types according to what is specified in the configuration class.
`conf_to_init_kwargs()` ^inherited	Turn a configuration object into a dictionary suitable for passing to `__init__` as `**kwargs`.
`from_conf()` ^inherited	Build an instance of `EnergyMeter` from a configuration object.
`get_logger()` ^inherited	Provides a `logging.Logger` named after `cls`.
`log_locals()` ^inherited	Debugging aid: log the local variables of the calling function.

Attributes#

ACME.INIT_KWARGS_KEY_MAP = {'channel_map': ['channel-map'], 'host': ['host'], 'iio_capture_bin': ['iio-capture-bin']}#

Dictionary of __init__ parameter names to configuration key path.

That path is a list of strings to take into account sublevels like ['level-key', 'sublevel', 'foo'].

ACME.REPORT_DELAY_S = 2.0#: iio-capture returns an empty string if killed right after its invocation, so we have to enforce a delay between reset() and report()
