Detailed Description

Class used to communicate with a NETIO4 intelligent power outlet. This is used to switch neuromorphic hardware devices on and off, as bugs in the hardware sometimes cause them to become responseless, causing experiments to crash with an exception.

Constructor & Destructor Documentation

cypress::NetIO4::NetIO4

(

cypress::Json &

config

)

Reads the NetIO4Power configuration from the given json configuration. The configuration must have the following format:

{ "address": "192.168.1.78", "port": 1234, "user": "admin", "password": "admin", "device_map": { "spikey": 1, "nmmc1": 2 } }

cypress::NetIO4::~NetIO4 ( )

inlineoverride

cypress::NetIO4::NetIO4 ( const std::string &  config_filename = ".netio4_config.json" )

explicit

Reads the NetIO4Power configuration from the given JSON file. See the other constructor for the expected format. If the file is not found, the NetIO4Power class will simply do nothing.

Parameters

config_filename

is the name of the file from which the configuration should be read.

Member Function Documentation

bool cypress::NetIO4::connected

(

)

Returns true if the class can successfully communicate with the device.

int cypress::NetIO4::device_port

(

const std::string &

device

)

Returns the port the given device is connected to. The device name must be the cannonical backend name as returned by "backend.name()". Returns -1 if no port is mapped to the given device.

bool cypress::NetIO4::has_config ( )

inlineoverridevirtual

Returns true if the configuration was sucessfully read in the constructor.

Implements cypress::PowerDevice.

bool cypress::NetIO4::state

(

int

port

)

Returns true if the port with the given port id is currently switched on, false if the device is switched off. Throws an exception if the communication with the device fails or the given port does not exist.

bool cypress::NetIO4::state ( const std::string &  device )

overridevirtual

Returns the state of the device with the given name. If the device cannot be controlled, false should be returned.

Parameters

device

is the canonical backend name (returned by backend.name()) of the device for which the state should be returned.

Returns

true if the device is currently switched on, false in all other cases.

Implements cypress::PowerDevice.

void cypress::NetIO4::switch_off

(

int

port

)

bool cypress::NetIO4::switch_off ( const std::string &  device )

overridevirtual

Switches the device with teh given name off.

Parameters

device

is the canonical backend name (returned by backend.name()) of the device that should be controlled.

Returns

true if the operation was successful, false otherwise.

Implements cypress::PowerDevice.

void cypress::NetIO4::switch_on

(

int

port

)

bool cypress::NetIO4::switch_on ( const std::string &  device )

overridevirtual

Switches the device with teh given name on.

Parameters

device

is the canonical backend name (returned by backend.name()) of the device that should be controlled.

Returns

true if the operation was successful, false otherwise.

Implements cypress::PowerDevice.
