UID:
  • tinkerforge:brickimuv2:[UID]
Required firmware version:
  • 2.0.10
Firmware update supported:
  • no
Channels:

Parameters:
  • Magnetometer Rate – Type: Choice, Default: 20Hz
  • This option is auto-controlled in fusion mode.
  • Options: 2Hz, 6Hz, 8Hz, 10Hz, 15Hz, 20Hz, 25Hz, 30Hz

  • Gyroscope Range – Type: Choice, Default: 2000°/s
  • This option is auto-controlled in fusion mode.
  • Options: 2000°/s, 1000°/s, 500°/s, 250°/s, 125°/s

  • Gyroscope Bandwidth – Type: Choice, Default: 32Hz
  • This option is auto-controlled in fusion mode.
  • Options: 523Hz, 230Hz, 116Hz, 47Hz, 23Hz, 12Hz, 64Hz, 32Hz

  • Accelerometer Range – Type: Choice, Default: ±4G
  • This option is user selectable in all fusion modes.
  • Options: ±2G, ±4G, ±8G, ±16G

  • Accelerometer Bandwidth – Type: Choice, Default: 62.5Hz
  • This option is auto-controlled in fusion mode.
  • Options: 7.81Hz, 15.63Hz, 31.25Hz, 62.5Hz, 125Hz, 250Hz, 500Hz, 1000Hz

  • Sensor Fusion Mode – Type: Choice, Default: On
  • If the fusion mode is turned off, the Acceleration, Magnetic Field and Angular Velocity channels return uncalibrated and uncompensated sensor data. All other sensor channels 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. By default sensor fusion is on.
  • Options: Off, On, On Without Magnetometer, On Without Fast Magnetometer Calibration

  • Acceleration Update Interval – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295
  • Specifies the update interval for the acceleration in milliseconds. A value of 0 disables automatic updates.

  • Magnetic Field Update Interval – Type: integer, Default: 1000, Unit: ms, Min: 0, Max: 4294967295

  • Specifies the update interval for the orientation as euler angles in milliseconds. A value of 0 disables automatic updates.

  • Status LED Configuration – Type: boolean, Default: true
  • The status LED is the blue LED next to the USB connector. If enabled is is on and it flickers if data is transfered. If disabled it is always off.

  • SPITFP Enable Dynamic Baudrate – Type: boolean, Default: true
  • The SPITF protocol can be used with a dynamic baudrate. If the dynamic baudrate is enabled, the Brick will try to adapt the baudrate for the communication between Bricks and Bricklets according to the amount of data that is transferred. The baudrate will be increased exponentially if lots of data is sent/received and decreased linearly if little data is sent/received. This lowers the baudrate in applications where little data is transferred (e.g. a weather station) and increases the robustness. If there is lots of data to transfer (e.g. Thermal Imaging Bricklet) it automatically increases the baudrate as needed. In cases where some data has to transferred as fast as possible every few seconds (e.g. RS485 Bricklet with a high baudrate but small payload) you may want to turn the dynamic baudrate off to get the highest possible performance. The maximum value of the baudrate can be set per port. If the dynamic baudrate is disabled, the maximum baudrate will be used statically.

  • SPITFP Minimum Dynamic Baudrate – Type: integer, Default: 400000, Min: 400000, Max: 2000000
  • See SPITFP Enable Dynamic Baudrate

  • (Maximum) SPITFP Baudrate Port A – Type: integer, Default: 1400000, Min: 400000, Max: 2000000
  • The baudrate for Bricklet port A. If you want to increase the throughput of Bricklets you can increase the baudrate. If you get a high error count because of high interference you can decrease the baudrate. If the dynamic baudrate feature is enabled, this is the maximum baudrate. Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.

  • (Maximum) SPITFP Baudrate Port B – Type: integer, Default: 1400000, Min: 400000, Max: 2000000
  • The baudrate for Bricklet port B. If you want to increase the throughput of Bricklets you can increase the baudrate. If you get a high error count because of high interference you can decrease the baudrate. If the dynamic baudrate feature is enabled, this is the maximum baudrate. Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.

brickIMUV2GetSensorFusionMode()
Return Map:
  • mode – Type: short, Range: See constants, Default: 1

Returns the sensor fusion mode as set by the thing configuration.

The following constants are available for this function:

For mode:

  • val SENSOR_FUSION_OFF = 0
  • val SENSOR_FUSION_ON = 1
  • val SENSOR_FUSION_ON_WITHOUT_MAGNETOMETER = 2
  • val SENSOR_FUSION_ON_WITHOUT_FAST_MAGNETOMETER_CALIBRATION = 3

brickIMUV2GetIdentity()
Return Map:
  • uid – Type: String, Length: up to 8
  • connectedUid – Type: String, Length: up to 8
  • position – Type: char, Range: ['0' to '8']
  • hardwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • firmwareVersion – Type: short[], Length: 3
    • 0: major – Type: short, Range: [0 to 255]
    • 1: minor – Type: short, Range: [0 to 255]
    • 2: revision – Type: short, Range: [0 to 255]
  • deviceIdentifier – Type: int, Range: [0 to 216 - 1]

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

The position is the position in the stack from '0' (bottom) to '8' (top).

The device identifier numbers can be found here. 

brickIMUV2IsStatusLEDEnabled()
Return Map:
  • enabled – Type: boolean, Default: true

Returns true if the status LED is enabled, false otherwise.

brickIMUV2GetChipTemperature()
Return Map:
  • temperature – Type: short, Unit: 1/10 °C, Range: [-215 to 215 - 1]

Returns the temperature as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has an accuracy of ±15%. Practically it is only useful as an indicator for temperature changes.

brickIMUV2GetSendTimeoutCount(short communicationMethod)
Parameters:
  • communicationMethod – Type: short, Range: See constants
Return Map:
  • timeoutCount – Type: long, Range: [0 to 232 - 1]

Returns the timeout count for the different communication methods.

The methods 0-2 are available for all Bricks, 3-7 only for Master Bricks.

This function is mostly used for debugging during development, in normal operation the counters should nearly always stay at 0.

The following constants are available for this function:

For communicationMethod:

  • val COMMUNICATION_METHOD_NONE = 0
  • val COMMUNICATION_METHOD_USB = 1
  • val COMMUNICATION_METHOD_SPI_STACK = 2
  • val COMMUNICATION_METHOD_CHIBI = 3
  • val COMMUNICATION_METHOD_RS485 = 4
  • val COMMUNICATION_METHOD_WIFI = 5
  • val COMMUNICATION_METHOD_ETHERNET = 6
  • val COMMUNICATION_METHOD_WIFI_V2 = 7

brickIMUV2GetSPITFPBaudrateConfig()
Return Map:
  • enableDynamicBaudrate – Type: boolean, Default: true
  • minimumDynamicBaudrate – Type: long, Unit: 1 Bd, Range: [400000 to 2000000], Default: 400000

Returns the baudrate config, see the thing configuration.

Neu in Version 2.0.10 (Firmware).

brickIMUV2GetSPITFPErrorCount(char brickletPort)
Parameters:
  • brickletPort – Type: char, Range: ['a' to 'b']
Return Map:
  • errorCountACKChecksum – Type: long, Range: [0 to 232 - 1]
  • errorCountMessageChecksum – Type: long, Range: [0 to 232 - 1]
  • errorCountFrame – Type: long, Range: [0 to 232 - 1]
  • errorCountOverflow – Type: long, Range: [0 to 232 - 1]

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

The errors are divided into

  • ACK checksum errors,
  • message checksum errors,
  • framing errors and
  • overflow errors.

The errors counts are for errors that occur on the Brick side. All Bricklets have a similar function that returns the errors on the Bricklet side.

Neu in Version 2.0.5 (Firmware).

brickIMUV2GetSPITFPBaudrate(char brickletPort)
Parameters:
  • brickletPort – Type: char, Range: ['a' to 'b']
Return Map:
  • baudrate – Type: long, Unit: 1 Bd, Range: [400000 to 2000000], Default: 1400000

Returns the baudrate for a given Bricklet port, see the thing configuration.
