func (*IMUV3Bricklet) GetResponseExpected

func (device *IMUV3Bricklet) 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 (*IMUV3Bricklet) GetSPITFPErrorCount

func (device *IMUV3Bricklet) GetSPITFPErrorCount() (errorCountAckChecksum uint32, errorCountMessageChecksum uint32, errorCountFrame uint32, errorCountOverflow uint32, err error)

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

func (*IMUV3Bricklet) SetGravityVectorCallbackConfiguration

func (device *IMUV3Bricklet) SetGravityVectorCallbackConfiguration(period uint32, valueHasToChange bool) (err error)

The period is the period with which the RegisterGravityVectorCallback callback is triggered periodically. A value of 0 turns the callback off.

If the `value has to change`-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

func (*IMUV3Bricklet) SetResponseExpected

func (device *IMUV3Bricklet) SetResponseExpected(functionID Function, responseExpected bool) error

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always 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.

func (*IMUV3Bricklet) SetResponseExpectedAll

func (device *IMUV3Bricklet) SetResponseExpectedAll(responseExpected bool)

Changes the response expected flag for all setter and callback configuration functions of this device at once.

func (*IMUV3Bricklet) SetSensorConfiguration

func (device *IMUV3Bricklet) SetSensorConfiguration(magnetometerRate MagnetometerRate, gyroscopeRange GyroscopeRange, gyroscopeBandwidth GyroscopeBandwidth, accelerometerRange AccelerometerRange, accelerometerBandwidth AccelerometerBandwidth) (err error)

Sets the available sensor configuration for the Magnetometer, Gyroscope and Accelerometer. The Accelerometer Range is user selectable in all fusion modes, all other configurations are auto-controlled in fusion mode.

Associated constants:

* MagnetometerRate2Hz
* MagnetometerRate6Hz
* MagnetometerRate8Hz

func (*IMUV3Bricklet) SetSensorFusionMode

func (device *IMUV3Bricklet) SetSensorFusionMode(mode SensorFusion) (err error)

If the fusion mode is turned off, the functions GetAcceleration, GetMagneticField and GetAngularVelocity return uncalibrated and uncompensated sensor data. All other sensor data getters return no data.

Since firmware version 2.0.6 you can also use a fusion mode without magnetometer. In this mode the calculated orientation is relative (with magnetometer it is absolute with respect to the earth). However, the calculation can't be influenced by spurious magnetic fields.

Since firmware version 2.0.13 you can also use a fusion mode without fast magnetometer calibration. This mode is the same as the normal fusion mode, but the fast magnetometer calibration is turned off. So to find the orientation the first time will likely take longer, but small magnetic influences might not affect the automatic calibration as much.

Associated constants:

* SensorFusionOff
* SensorFusionOn
* SensorFusionOnWithoutMagnetometer
* SensorFusionOnWithoutFastMagnetometerCalibration

func (*IMUV3Bricklet) SetStatusLEDConfig

func (device *IMUV3Bricklet) SetStatusLEDConfig(config StatusLEDConfig) (err error)

Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.

You can also turn the LED permanently on/off or show a heartbeat.

If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.

Associated constants:

* StatusLEDConfigOff
* StatusLEDConfigOn
* StatusLEDConfigShowHeartbeat
* StatusLEDConfigShowStatus

func (*IMUV3Bricklet) SetTemperatureCallbackConfiguration

func (device *IMUV3Bricklet) SetTemperatureCallbackConfiguration(period uint32, valueHasToChange bool) (err error)

The period is the period with which the RegisterTemperatureCallback callback is triggered periodically. A value of 0 turns the callback off.

If the `value has to change`-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

func (*IMUV3Bricklet) SetWriteFirmwarePointer

func (device *IMUV3Bricklet) SetWriteFirmwarePointer(pointer uint32) (err error)

Sets the firmware pointer for WriteFirmware. The pointer has to be increased by chunks of size 64. The data is written to flash every 4 chunks (which equals to one page of size 256).

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

func (*IMUV3Bricklet) WriteFirmware

func (device *IMUV3Bricklet) WriteFirmware(data [64]uint8) (status uint8, err error)

Writes 64 Bytes of firmware at the position as written by SetWriteFirmwarePointer before. The firmware is written to flash every 4 chunks.

You can only write firmware in bootloader mode.

This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

func (*IMUV3Bricklet) WriteUID

func (device *IMUV3Bricklet) WriteUID(uid uint32) (err error)

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.
