Description
The LSM303C IMU Sensor block outputs the values of linear acceleration and magnetic field strength along x-, y- and z- axes as measured by the LSM303C sensor connected to Raspberry Pi® board. The block also outputs the temperature as read by the LSM303C sensor.
Ports
Output
Acceleration — Linear acceleration measured by LSM303C sensor
row vector
Linear acceleration (in m/s2) measured by LSM303C sensor connected to Raspberry Pi board, along the x-, y- and z- axes, specified as a row vector [x,y,z].
Dependencies
This output port appears only if you select the Acceleration (m/s2) parameter.
Data Types: double
Magnetic Field — Magnetic field strength measured by LSM303C sensor
row vector
Magnetic field strength (in µT) measured by LSM303C sensor connected to Raspberry Pi board, along the x-, y- and z- axes, specified as a row vector [x,y,z].
Dependencies
This output port appears only if you select the Magnetic Field (µT) parameter.
Data Types: double
Temperature — Temperature measured by LSM303C sensor
scalar
Temperature (in ℃) measured by LSM303C sensor connected to Raspberry Pi board.
Dependencies

Data Types: double
Acceleration Status — Status of acceleration value
0
| 1
Status of acceleration value along the three axes, specified as a row vector in
the order [z,y,x], to indicate if the data read is the new value or not.
0
indicates that the data read is new and 1
indicates that the data read is not new.
Dependencies
This output port appears only if you select the Acceleration Status parameter.
Data Types: Boolean
Magnetic Field Status — Status of magnetic field value
0
| 1
Status of magnetic field value along the three axes, specified as a row vector in
the order [z,y,x], to indicate if the data read is the new value or not.
0
indicates that the data read is new and 1
indicates that the data read is not new.
Dependencies
This output port appears only if you select the Magnetic Field Status parameter.
Data Types: double
Parameters
I2C module — Module for communication
1
(default)
Specify the module on the board that you are using for I2C communication.
Acceleration (m/s2) — Set output port for reading acceleration
on
(default) | off
Select this parameter to set Acceleration as one of the output ports.
Magnetic Field (µT) — Set output port for reading magnetic field
on
(default) | off
Select this parameter to set Magnetic Field as one of the output ports.
Temperature (℃) — Set output port for reading temperature
on
(default) | off
Select this parameter to set Temperature as one of the output ports.
Acceleration Status — Set output port for obtaining acceleration status
off
(default) | on
Select this parameter to set Acceleration Status as one of the output ports.
Magnetic Field Status — Set output port for obtaining magnetic field status
off
(default) | on
Select this parameter to set Magnetic Field Status as one of the output ports.
Sample time — Time interval to read data
-1
(default) | positive integer
Specify how often this block reads the data from the LSM303 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.

Accelerometer output data rate — Rate at which accelerometer data is sampled
10 Hz
(default) | 50 Hz
| 100 Hz
| 200 Hz
| 400 Hz
| 800 Hz
Select the output data rate at which accelerometer data is sampled, which also determines the bandwidth.
