About the BMX055

The BMX055 consists of BMA255, BMG160 and BMM150 in a single chip.

BMA255 is an advanced, ultra-small, tri-axial, low-g acceleration sensor with digital interfaces, aiming for low- power consumer electronics applications. Featuring 12 bit digital resolution, the BMX055 allows low noise measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration in cellular phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers.

The BMG160 is a three-axes-gyroscope device. It consists of a MEMS element and an ASIC within one package. It is capable to measure angular rates in three perpendicular room dimensions X, Y and Z-axis and to provide the corresponding the output signals

BMM150 is a three axis MEMS magnetometer. The magnetometer measures the components of the earth’s magnetic field (the geomagnetic field).

The packaging and interfaces of the BMM150 have been designed to match a multitude of hardware requirements. As the sensor features an ultra-small footprint and a flat package, it is ingeniously suited for mobile applications.

The BMM150 offers ultra-low voltage operation (VDD voltage range from 1.62V to 3.6V, VDDIO voltage range 1.2V to 3.6V) and can be programmed to optimize functionality, performance and power consumption in customer specific applications. The programmable interrupt engine sets new standards in terms of flexibility.

The BMM150 senses data ready, low threshold, high threshold and overflow in cell phones, handhelds, computer peripherals, man-machine interfaces, virtual reality features and game controllers. BMM150 sensor specific details can be referred in BMM150 sensor data sheet.

The configurations can be classified as basic and advanced configuration. The entire basic configurations are available in the General Settings panel. The advance configuration can be accessed by various panels available under Memory Map and Register Access.

Selecting accelerometer Bandwidth

Two different streams of sensor data are available, unfiltered and filtered. The unfiltered data is sampled at 2 kHz. The sampling rate of the filtered data depends on the selected filter bandwidth and is always twice the selected bandwidth. The band width can be selected from Accelerometer settings in the General Settings panel. Use the Bandwidth

Selecting accelerometer Range

The accelerometer range setting configures the measurement range of the accelerometer sensor. The range can be selected to 2G, 4G, 8G or 16G from Accelerometer settings in the General Settings panel.

Selecting accelerometer Operation Mode

BMX055 accelerometer sensor can be configured to any one of the operation modes by selecting the options available in the drop down menu. The operation mode can be selected from Accelerometer settings in the General Settings panel

Note: For a detailed description of the sensors power saving modes and their applications, refer to the BMX055 sensor data sheet.

Reset sensor

This feature can be used to bring the sensor back to its default state. All the configuration data are reset to the default values. This is a soft reset and can be triggered for accelerometer and magnetometer separately. Sensor can be reset by the button click under General Setting panel.

Power – On reset

This is hard reset functionality. The VDD and VDDIO are turned OFF and then ON. This triggers the power-on- reset circuitry of the sensor. PO Reset button is available under General Setting panel.

Binary View

In the binary view, the sensor registers are identified by their addresses. The values displayed are the actual representation of the sensor memory map. This view is available for both accelerometer and magnetometer. If exact addresses of the sensor registers are known, this view can be helpful in writing direct values to the sensor memory map.

The value entered is converted to binary format and is displayed in the Binary text box.

Click Write to transfer values to the actual registers.
Click Read to read the current register setting of the sensor in the memory map window.

To launch this view, click on Panels in the main menu and select Memory Map -> Binary View. Alternately, Ctrl + B can be used as a shortcut.

To launch this view, click on Panels in the main menu and select Memory Map -> Offset View. Alternately, Ctrl + O can be used as a shortcut

Interrupt configuration

The BMA255 is equipped with eight programmable interrupt engines. Each interrupt can be independently enabled and disabled. The BMA 255 provides two interrupt pins INT1 and INT2; interrupts can be freely mapped to any of these pins.

General feature

An interrupt is cleared depending on the selected interrupt modes which is common to all the interrupts. There are three different interrupt modes: non latched, latched and temporary. In non-latched mode the interrupt status bit and the selected pin is cleared as soon as activation condition is not valid. Exceptions to this behaviour are new data orientation and flat interrupts, which will automatically get reset after a fixed time. In latched mode the interrupt status bit and the selected pin are latched permanently. This will be cleared only on reset interrupt. In temporary mode an asserted interrupt status bit and the selected pin are cleared after a defined period of time.

It is strongly recommended to set the interrupt parameters prior to enabling the interrupt.

Changing the parameters of an already enabled interrupts may cause unwanted interrupt generation and generation of false interrupt history.

New data interrupt

This interrupt serves for synchronous reading of accelerometer data. It is generated after storing the new value of z-axis acceleration data in the data register. The interrupt is cleared automatically when the data acquisition starts.

The interrupt can be enabled by going to panels-> memory map->interrupt view and clicking on the data. If it needs to be mapped with the two interrupt pins INT1 and INT2 click on int1 and int2.

Slope / any motion detection

Slope / any motion detection use the slope between two successive acceleration values to detect the changes in motion. An interrupt is generated when the sloe exceeds a preset threshold. It is cleared soon as soon as the slope falls below the threshold. In order to suppress false triggers the interrupt is only generated (cleared) if a certain no N of consecutive slope data points is larger (small) than the threshold.

The interrupt can be enabled (disabled) for each axis by going to panels-> memory map->interrupt view and clicking on the Slope X, Y, Z. If it needs to be mapped with the two interrupt pins INT1 and INT2 click on int1 and int2.

Tap sensing

Tap sensing has a functionality similarity with a common laptop touch pad or clicking keys of a computer mouse. A tap event is detected if a predefined slope of the acceleration of at least one axis is exceeded. Two different tap events are distinguished. A single tap is a single event with a certain time, followed by a certain quiet time. A double tap consist of first such event followed by a second event with in a defined time frame.

Orientation recognition

The orientation recognition feature, informs the orientation change of the sensor with respect to the gravitational field vector ’g’. Orient can be enabled by clicking on orient in panels-> memory map->interrupt view-

>Interrupt mapping. It can be mapped with the two interrupt pins INT1 and INT2 by clicking onint1 and int2.

Flat detection

The flat detection feature gives information about the orient of the devices z- axis relative to the g-vector i.e. it recognizes whether the device is in flat position or not. The flat interrupt will occur when the device is in flat position and it will get cleared automatically after one sample period.

Low-g interrupt

This interrupt is based on the comparison of acceleration data against a low-g threshold, which is most useful for free fall detection. The low G threshold is set through the selection box threshold in low-g settings. The duration can be set. Mode can be ‘sum’ mode or ‘single’ mode and hysteresis.

High-G interrupt

This interrupt is based on the comparison of acceleration data against a high–g threshold for the detection of shock or other high-acceleration events. The high G threshold is set through the selection box threshold in high-g settings. The high-g duration can be also set through duration.

No motion/ slow motion detection

No motion/ slow motion detection interrupt engine can be configured in two modes. In slow motion mode an interrupt is triggered when the measured slope of at least one enabled axis exceeds the programmable slope

threshold for a programmable no of samples. In no-motion mode an interrupt is generated if the slope on all selected axis remains smaller than a programmable threshold for programmable delay time. After selecting all these write image need to be clicked.

Trim Registers

To launch this view, click on Panels in the main menu and select Memory Map -> Trim registers. Alternately, Ctrl + T can be used as a shortcut. To configure these registers, extended memory map should be enabled by checking Enable extended memory map checkbox. By enabling the extended memory map the stored and calculate CRC will be displayed. After making the changes to the register click on the write button to reflect in the sensor. Click on the read button to get the updated CRC.

FIFO Operation modes

The BMA255 features an integrated FIFO memory capable of storing 32 frames. Conceptually each frame consists of x, y, z axis which are sampled at same point in time.

FIFO can be operated in three modes.

BYPASS mode
FIFO mode
STREAM mode

BMG160 Sensor Configuration

Selecting the power mode

The BMG160 has four different power modes. Besides normal mode, which represents the fully operational state of the device, there are three energy saving modes: deep-suspend mode, suspend mode, and fast power up Sensor can be configured to any one of the modes can be selected from the scroll down menu.

After power-up BMG160 is in normal mode so that all parts of the device are held powered- up and data acquisition is performed continuously.

In deep suspend mode the device reaches the lowest possible power consumption. Only the interface section is kept alive. No data acquisition is performed and the content of the configuration is lost.
In suspend mode the complete analog part is powered down. No data acquisition is performed. While in suspend mode the latest angular rate data and the content of all configuration data are kept.
In fast power up mode the sensing analog part is powered down, while the digital part remains purely operational. No data acquisition is performed.
Using the mode option, mode of the sensor can be changed. The mode can be selected from the drop down list. By default, the Normal Mode is selected.

For a detailed description of the BMG160 power saving modes and their applications, refer to the BMG160 data sheet.

Selecting the band width

Two different streams of angular rate data are available, unfiltered and filtered. The unfiltered data is sampled at 2 kHz. The sampling rate of the filtered data depends on the selected filter bandwidth and is always twice the selected bandwidth.

The band width can be selected from general settings dropdown menu.

Selecting the range

The range can be selected from the drop down list. BMG160 supports five different measurement ranges.

2000o/s range
1200o/s range
500o/s range
250o/s range
125o/s range

Reset Sensor

A soft reset causes all user configuration settings to be overwritten with their default values and sensor enters to the normal mode.

Click the Reset button to soft reset the sensor.

Reset Interrupt

This will reset any active interrupt. The interrupt will again occur only if the interrupt is enabled and the particular interrupt condition occurs.

Binary View

Click Read to read the current register setting of the sensor in the memory map window.

To launch this view, click on Panels in the main menu and select Memory Map -> Binary View. Alternately, Ctrl + B can be used as a shortcut.

OFFSET view

Offset in measured signals can have several causes but there are unwanted and disturbing in many cases. Therefore four digital compensation methods are offered. These are slow, fast and manual compensation as well as inline calibration. The compensation is performed with the filtered data, and is then applied to both, unfiltered and filtered data.

To launch this view, click on Panels in the main menu and select Memory Map -> Offset View. Alternately, Ctrl + O can be used as a shortcut. The OFFSET View can be selected by clicking on panels-> memory map-> OFFSET view.

Interrupt configuration

BMM150 sensor provides INT1 for magnetometer. The sensor interrupts can be independently enabled or disabled and can be freely mapped to interrupt pin. To launch this view, click on Panels in the main menu and select Memory Map -> Interrupt View Or Press

Enable Interrupt Pin

Enable interrupt works based on the pin out from the sensor. If the interrupt pin is enabled and if, an interrupt occurs, this pin will go high and will remain high until interrupt is cleared. When this interrupt pin is disabled, even if any interrupt occurs it will not go high. Note: The interrupt pin is high-Z when disabled as it does not have a defined voltage level.

Overflow Interrupt

If overflow interrupt is enabled, and if, any of the X, Y and Z values exceeds the maximum value, then an interrupt is generated and the interrupt indicator turns green.

Enabling Low/High level IRQs

BMM150 provides two interrupts for the magnetic part: low level and high level IRQs. Low level and high level IRQs can be activated separately for each magnetic axis of BMM150 by checking the corresponding checkboxes.

Setting thresholds

Low level IRQ is issued when one of the activated axes (logic OR) is less than the value set in Threshold Low field. High level IRQ is issued when one of the activated axes (logic OR) exceeds the value set in Threshold High field.

Note: Both Threshold Low and Threshold High are expressed in “μT” units. However, the internal interrupt engine only compares the uncompensated ADC values to the selected threshold. This means that the accuracy of the setting is limited.

Latch IRQ

Checking the Latch IRQ checkbox enables IRQ latching, which means that the interrupt pin stays high after an interrupt event until the interrupt status register is read. After reading, the register is cleared. If latching is disabled, the interrupt status register will always reflect the result of the last measurement and retain its value until the next measurement is finished.

Magnetic sensor IRQ status display

The MAG interrupts tab shows the status of the magnetic interrupts of BMM150 and the status of the IRQ pin.

Register Access

To launch this view, click on Panels in the main menu and select Register Access Or Press Ctrl + R

Self Test

The Self Test menu permits to check the sensor functionality by applying electrostatic forces to the sensor core instead of external accelerations.

The Self Test View can be selected by clicking on panels-> memory map-> Self Test view. The self test is activated individually for each axis by selecting each axis from the drop down list. The direction of excitation can be chosen by clicking self-test sign from the drop down menu.

The Self Test menu enables access to the self test features of the magnetic sensor.

During normal self-test, the following processes are executed

FlipCore signal path is verified by generating signals on-chip. These are processed through the signal path and the measurement result is compared to known thresholds.
FlipCore (X and Y) bondwires to ASIC are checked for connectivity.
FlipCore (X and Y) bondwires and MEMS are checked for shorting.
Hall sensor connectivity is checked for open and shorted connections.
Hall sensor signal path and hall sensor element offset are checked for overflow.

The sensor features an internal coil-on-chip advance self test mode. Advanced self test can be performed only for z axis.

Click the Adv Self Test button to display the result of the advanced self test. The value indicated after the advanced self test should be around 200 µT.
