Description
The BMI160 block outputs the values of linear acceleration and angular rate along X, Y, and Z axes as measured by the BMI160 sensor connected to an NVIDIA® embedded board. The block also outputs the temperature as read by the BMI160 sensor. If you connect the BMM150 as a secondary sensor to BMI160, the BMI160 block also outputs magnetic field along X, Y, and Z axes as measured by the BMM150 sensor.
The block supports single tap, double tap, high-g detection, any-motion, slow-motion, flat detection, and data ready interrupts.
Interrupt source output is a 1
-by-7
vector with
elements corresponding to the source of single tap, double tap, high-g detection,
any-motion, slow-motion, flat detection, and data ready
interrupts respectively. 1
indicates that it is the source,
0
indicates that it is not a source, and -1
indicates
that the interrupt is not active.
Tap source output is a 1
-by-4
vector, with the first
three elements indicating whether the single tap/double tap occurred in X, Y and Z axis, and
the fourth element indicating whether it is on positive or negative direction of the axis.
High-g source output is a 1
-by-4
vector, with the first
three elements indicating whether the high-g interrupt occurred in X,Y and Z axis and the
fourth element indicating whether it is on positive or negative direction of the axis.
Any-motion source output is a
1
-by-4
vector which shows on which of the X,Y and Z
axis did the any-motion interrupt occur and whether it is
on positive or negative direction of the axis. First byte denotes whether the event occurred
on X axis, second byte denotes whether the event occurred on Y axis, third byte denotes
whether the event occurred on Z axis and fourth byte denotes the direction. For direction byte
0
denotes negative side and 1
denotes positive and for
other bytes 1 denotes that axis is the source and 0
denotes that axis is
not the source.
When interrupts are enabled use external interrupt block and develop respective function call subsystem.

'INT2' |
Default: 'INT1' |
Flat detection — Enable interrupt when flat detection interrupt is triggered
-1
(default) | positive integer
If this option is selected, an interrupt is generated on pin INT1 or INT2 of the sensor when flat detection interrupt is detected.
Programmatic Use
Block Parameter:
isFlatDetection |
Type: character vector |
Values: 'on' |
'off' |
Default: 'off' |
Theta threshold (0.7° to 44.8°) — Theta threshold for detecting flat detection interrupt
5
(default)
Specify the amplitude threshold value ranging from 0.7° - 44.8° for detecting flat detection interrupt. When the value crosses the specified amplitude threshold value, flat detection interrupt is detected.
Dependencies
This parameter appears only if you select Flat detection parameter.
Programmatic Use
Block Parameter:
FlatThetaThreshold |
Type: character vector |
Values: '0.7' to
'44.8' |
Default: '5' |
Time threshold — Time duration for flat detection interrupt
640
(default) | 0
| 1280
| 2560
Select the time threshold value for flat detection interrupt. The flat detection interrupt must occur during the specified time threshold.
Dependencies
This parameter appears only if you select Flat detection parameter.
Programmatic Use
Block Parameter:
FlatTimeThreshold |
Type: character vector |
Values: '0' |
'640' | '1280' |
'2560' |
Default: '640' |
Interrupt generate pin — Pin to generate flat detection interrupt
INT1
(default) | INT2
Select the pin on which the flat detection interrupt, which can be used by the NVIDIA board, gets generated on the sensor.
Dependencies
This parameter appears only if you select the Flat detection parameter.
Programmatic Use
Block Parameter:
InterruptPinFlat |
Type: character vector |
Values: 'INT1' |
'INT2' |
Default: 'INT1' |
Data ready — Enable interrupt when data is ready
off
(default) | on
If this option is selected, an interrupt is generated on pin INT1 or INT2 of the sensor when data is ready, allowing you to trigger other subsystems to perform an action.
Programmatic Use
Block Parameter:
isDataReady |
Type: character vector |
Values: 'on' |
'off' |
Default: 'off' |
Interrupt generate pin — Pin to generate data ready interrupt
INT1
(default) | INT2
Select the pin on which the data ready interrupt, which can be used by the NVIDIA board, gets generated on the sensor.
Dependencies
This parameter appears only if you select the Enable data ready interrupt parameter.
Programmatic Use
Block Parameter:
InterruptPinDataReady |
Type: character vector |
Values: 'INT1' |
'INT2' |
Default: 'INT1' |
Data type — Output data type for values from BMI160 sensor
single
(default) | double
Specify the output data type for the values read from BMI160 sensor. The default
data type for NVIDIA board is single
. Use this parameter to change the
values to double
, if required.
Programmatic Use
Block Parameter:
DataType |
Type: character vector |
Values: 'single' |
'double' |
Default: 'single' |
Sample time — Time interval to read data
-1
(default) | scalar | vector
Specify how often this block reads the data from the BMI160 sensor. When you set this parameter to -1, Simulink® determines the best sample time for the block based on the block context within the model.
Programmatic Use
Block Parameter:
SampleTime

Type: character vector |
Values: scalar | vector |
Default:
'0.1'
