'Accelerometer Bricklet 2.0'
CALLBACK_ACCELERATION =

This callback is triggered periodically according to the configuration set by BrickletAccelerometerV2#set_acceleration_callback_configuration.

The parameters are the same as BrickletAccelerometerV2#get_acceleration.

8
CALLBACK_CONTINUOUS_ACCELERATION_16_BIT =

Returns 30 acceleration values with 16 bit resolution. The data rate can be configured with BrickletAccelerometerV2#set_configuration and this callback can be enabled with BrickletAccelerometerV2#set_continuous_acceleration_configuration.

The returned values are raw ADC data. If you want to put this data into a FFT to determine the occurrences of specific frequencies we recommend that you use the data as is. It has all of the ADC noise in it. This noise looks like pure noise at first glance, but it might still have some frequnecy information in it that can be utilized by the FFT.

Otherwise you have to use the following formulas that depend on the full scale range (see BrickletAccelerometerV2#set_configuration) to calculate the data in gₙ/10000 (same unit that is returned by BrickletAccelerometerV2#get_acceleration):

  • Full scale 2g: acceleration = value * 625 / 1024

  • Full scale 4g: acceleration = value * 1250 / 1024

  • Full scale 8g: acceleration = value * 2500 / 1024

The data is formated in the sequence “x, y, z, x, y, z, …” depending on the enabled axis. Examples:

  • x, y, z enabled: “x, y, z, …” 10x repeated

  • x, z enabled: “x, z, …” 15x repeated

  • y enabled: “y, …” 30x repeated

11
CALLBACK_CONTINUOUS_ACCELERATION_8_BIT =

Returns 60 acceleration values with 8 bit resolution. The data rate can be configured with BrickletAccelerometerV2#set_configuration and this callback can be enabled with BrickletAccelerometerV2#set_continuous_acceleration_configuration.

The returned values are raw ADC data. If you want to put this data into a FFT to determine the occurrences of specific frequencies we recommend that you use the data as is.

  • Full scale 2g: acceleration = value * 256 * 625 / 1024

  • Full scale 4g: acceleration = value * 256 * 1250 / 1024

  • Full scale 8g: acceleration = value * 256 * 2500 / 1024

The data is formated in the sequence “x, y, z, x, y, z, …” depending on the enabled axis. Examples:

  • x, y, z enabled: “x, y, z, …” 20x repeated

  • x, z enabled: “x, z, …” 30x repeated

  • y enabled: “y, …” 60x repeated

Instance Method Details

#get_acceleration ⇒ Object

Returns the acceleration in x, y and z direction. The values are given in gₙ/10000 (1gₙ = 9.80665m/s²). The range is configured with BrickletAccelerometerV2#set_configuration.

If you want to get the acceleration periodically, it is recommended to use the CALLBACK_ACCELERATION callback and set the period with BrickletAccelerometerV2#set_acceleration_callback_configuration.

#get_chip_temperature ⇒ Object

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 bad accuracy. Practically it is only useful as an indicator for temperature changes.

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 :ref:‘Isolator Bricklet <isolator_bricklet>` is always at position ’z’.

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

#get_spitfp_error_count ⇒ Object

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 Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

end

#reset ⇒ Object

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

end

#set_acceleration_callback_configuration(period, value_has_to_change) ⇒ Object

The period is the period with which the CALLBACK_ACCELERATION 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 this callback is enabled, the CALLBACK_CONTINUOUS_ACCELERATION_16_BIT callback and CALLBACK_CONTINUOUS_ACCELERATION_8_BIT callback will automatically be disabled.

end

#set_bootloader_mode(mode) ⇒ Object

Sets the bootloader mode and returns the status after the requested mode change was instigated.

You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.

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

#set_configuration(data_rate, full_scale) ⇒ Object

Configures the data rate and full scale range. Possible values are:

  • Data rate of 0.781Hz to 25600Hz.

  • Full scale range of ±2g up to ±8g.

Decreasing data rate or full scale range will also decrease the noise on the data.

end

#set_continuous_acceleration_configuration(enable_x, enable_y, enable_z, resolution) ⇒ Object

For high throughput of acceleration data (> 1000Hz) you have to use the CALLBACK_CONTINUOUS_ACCELERATION_16_BIT or CALLBACK_CONTINUOUS_ACCELERATION_8_BIT callbacks.

You can enable the callback for each axis (x, y, z) individually and choose a resolution of 8 bit or 16 bit.

If at least one of the axis is enabled and the resolution is set to 8 bit, the CALLBACK_CONTINUOUS_ACCELERATION_8_BIT callback is activated. If at least one of the axis is enabled and the resolution is set to 16 bit, the CALLBACK_CONTINUOUS_ACCELERATION_16_BIT callback is activated.

The returned values are raw ADC data. If you want to put this data into a FFT to determine the occurrences of specific frequencies we recommend that you use the data as is. It has all of the ADC noise in it. This noise looks like pure noise at first glance, but it might still have some frequnecy information in it that can be utilized by the FFT.

Otherwise you have to use the following formulas that depend on the configured resolution (8/16 bit) and the full scale range (see BrickletAccelerometerV2#set_configuration) to calculate the data in gₙ/10000 (same unit that is returned by BrickletAccelerometerV2#get_acceleration):

  • 16 bit, full scale 2g: acceleration = value * 625 / 1024

  • 16 bit, full scale 4g: acceleration = value * 1250 / 1024

  • 16 bit, full scale 8g: acceleration = value * 2500 / 1024

If a resolution of 8 bit is used, only the 8 most significant bits will be transferred, so you can use the following formulas:

  • 8 bit, full scale 2g: acceleration = value * 256 * 625 / 1024

  • 8 bit, full scale 4g: acceleration = value * 256 * 1250 / 1024

  • 8 bit, full scale 8g: acceleration = value * 256 * 2500 / 1024

If no axis is enabled, both callbacks are disabled. If one of the continuous callbacks is enabled, the CALLBACK_ACCELERATION callback is disabled.

The maximum throughput depends on the exact configuration:

"Number of axis enabled", "Throughput 8 bit", "Throughout 16 bit"

"1", "25600Hz", "25600Hz"
"2", "25600Hz", "15000Hz"
"3", "20000Hz", "10000Hz"

end

#set_filter_configuration(iir_bypass, low_pass_filter) ⇒ Object

Configures IIR Bypass filter mode and low pass filter roll off corner frequency.

The filter can be applied or bypassed and the corner frequency can be half or a ninth of the output data rate.

#set_status_led_config(config) ⇒ Object

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.

#set_write_firmware_pointer(pointer) ⇒ Object

Sets the firmware pointer for BrickletAccelerometerV2#write_firmware. 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.
