Types

type AnalogInBricklet 

type AnalogInBricklet struct {
	// contains filtered or unexported fields
}

func New 

func New(uid string, ipcon *ipconnection.IPConnection) (AnalogInBricklet, error)

Creates an object with the unique device ID `uid`. This object can then be used after the IP Connection `ipcon` is connected.

func (*AnalogInBricklet) DeregisterAnalogValueCallback 

func (device *AnalogInBricklet) DeregisterAnalogValueCallback(registrationId uint64)

Remove a registered Analog Value callback.

func (*AnalogInBricklet) DeregisterAnalogValueReachedCallback 

func (device *AnalogInBricklet) DeregisterAnalogValueReachedCallback(registrationId uint64)

Remove a registered Analog Value Reached callback.

func (*AnalogInBricklet) DeregisterVoltageCallback 

func (device *AnalogInBricklet) DeregisterVoltageCallback(registrationId uint64)

Remove a registered Voltage callback.

func (*AnalogInBricklet) DeregisterVoltageReachedCallback 

func (device *AnalogInBricklet) DeregisterVoltageReachedCallback(registrationId uint64)

Remove a registered Voltage Reached callback.

func (*AnalogInBricklet) GetAPIVersion 

func (device *AnalogInBricklet) GetAPIVersion() [3]uint8

Returns the version of the API definition (major, minor, revision) implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

func (*AnalogInBricklet) GetAnalogValue 

func (device *AnalogInBricklet) GetAnalogValue() (value uint16, err error)

Returns the value as read by a 12-bit analog-to-digital converter.

Note 

The value returned by GetVoltage is averaged over several samples
to yield less noise, while GetAnalogValue gives back raw
unfiltered analog values. The only reason to use GetAnalogValue is,
if you need the full resolution of the analog-to-digital converter.

If you want the analog value periodically, it is recommended to use the RegisterAnalogValueCallback callback and set the period with SetAnalogValueCallbackPeriod.

func (*AnalogInBricklet) GetAnalogValueCallbackPeriod 

func (device *AnalogInBricklet) GetAnalogValueCallbackPeriod() (period uint32, err error)

Returns the period as set by SetAnalogValueCallbackPeriod.

func (*AnalogInBricklet) GetAnalogValueCallbackThreshold 

func (device *AnalogInBricklet) GetAnalogValueCallbackThreshold() (option ThresholdOption, min uint16, max uint16, err error)

Returns the threshold as set by SetAnalogValueCallbackThreshold.

Associated constants:

  • ThresholdOptionOff
  • ThresholdOptionOutside
  • ThresholdOptionInside
  • ThresholdOptionSmaller
  • ThresholdOptionGreater

func (*AnalogInBricklet) GetAveraging 

func (device *AnalogInBricklet) GetAveraging() (average uint8, err error)

Returns the averaging configuration as set by SetAveraging.

.. versionadded:: 2.0.3$nbsp;(Plugin)

func (*AnalogInBricklet) GetDebouncePeriod 

func (device *AnalogInBricklet) GetDebouncePeriod() (debounce uint32, err error)

Returns the debounce period as set by SetDebouncePeriod.

func (*AnalogInBricklet) GetIdentity 

func (device *AnalogInBricklet) GetIdentity() (uid string, connectedUid string, position rune, hardwareVersion [3]uint8, firmwareVersion [3]uint8, deviceIdentifier uint16, err error)

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an `Isolator Bricklet <isolator_bricklet>` is always at position 'z'.

The device identifier numbers can be found `here <device_identifier>`. |device_identifier_constant|

func (*AnalogInBricklet) GetRange 

func (device *AnalogInBricklet) GetRange() (range_ Range, err error)

Returns the measurement range as set by SetRange.

.. versionadded:: 2.0.1$nbsp;(Plugin)

Associated constants:

  • RangeAutomatic
  • RangeUpTo6V
  • RangeUpTo10V
  • RangeUpTo36V
  • RangeUpTo45V
  • RangeUpTo3V

func (*AnalogInBricklet) GetResponseExpected 

func (device *AnalogInBricklet) GetResponseExpected(functionID Function) (bool, error)

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by SetResponseExpected. For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

See SetResponseExpected for the list of function ID constants available for this function.

func (*AnalogInBricklet) GetVoltage 

func (device *AnalogInBricklet) GetVoltage() (voltage uint16, err error)

Returns the voltage of the sensor. The resolution between 0 and 6V is about 2mV. Between 6 and 45V the resolution is about 10mV.

If you want to get the voltage periodically, it is recommended to use the RegisterVoltageCallback callback and set the period with SetVoltageCallbackPeriod.

func (*AnalogInBricklet) GetVoltageCallbackPeriod 

func (device *AnalogInBricklet) GetVoltageCallbackPeriod() (period uint32, err error)

Returns the period as set by SetVoltageCallbackPeriod.

func (*AnalogInBricklet) GetVoltageCallbackThreshold 

func (device *AnalogInBricklet) GetVoltageCallbackThreshold() (option ThresholdOption, min uint16, max uint16, err error)

Returns the threshold as set by SetVoltageCallbackThreshold.

Associated constants:

  • ThresholdOptionOff
  • ThresholdOptionOutside
  • ThresholdOptionInside
  • ThresholdOptionSmaller
  • ThresholdOptionGreater

func (*AnalogInBricklet) RegisterAnalogValueCallback 

func (device *AnalogInBricklet) RegisterAnalogValueCallback(fn func(uint16)) uint64

This callback is triggered periodically with the period that is set by SetAnalogValueCallbackPeriod. The parameter is the analog value of the sensor.

The RegisterAnalogValueCallback callback is only triggered if the voltage has changed since the last triggering.

func (*AnalogInBricklet) RegisterAnalogValueReachedCallback 

func (device *AnalogInBricklet) RegisterAnalogValueReachedCallback(fn func(uint16)) uint64

This callback is triggered when the threshold as set by SetAnalogValueCallbackThreshold is reached. The parameter is the analog value of the sensor.

If the threshold keeps being reached, the callback is triggered periodically with the period as set by SetDebouncePeriod.

func (*AnalogInBricklet) RegisterVoltageCallback 

func (device *AnalogInBricklet) RegisterVoltageCallback(fn func(uint16)) uint64

This callback is triggered periodically with the period that is set by SetVoltageCallbackPeriod. The parameter is the voltage of the sensor.

The RegisterVoltageCallback callback is only triggered if the voltage has changed since the last triggering.

func (*AnalogInBricklet) RegisterVoltageReachedCallback 

func (device *AnalogInBricklet) RegisterVoltageReachedCallback(fn func(uint16)) uint64

This callback is triggered when the threshold as set by SetVoltageCallbackThreshold is reached. The parameter is the voltage of the sensor.

If the threshold keeps being reached, the callback is triggered periodically with the period as set by SetDebouncePeriod.

func (*AnalogInBricklet) SetAnalogValueCallbackPeriod 

func (device *AnalogInBricklet) SetAnalogValueCallbackPeriod(period uint32) (err error)

Sets the period with which the RegisterAnalogValueCallback callback is triggered periodically. A value of 0 turns the callback off.
