c ROS node wrapper for the mpu9255 gyroscope / accelerometer/magnetometer.
Reads accelerometer, gyroscopic and magnetic data in 3D giving 9 Degrees of Freedom.
Publishes sensor_msgs::IMU to /imu/data_raw topic(angular_velocity and linear_acceleration).
Publishes sensor_msgs::MagneticField to /imu/data_raw topic(angular_velocity and linear_acceleration).
Supported interface : I2C.
used in Raspberry PI 3.\
First install WiringPI:
cd
git clone git://git.drogon.net/wiringPi
cd ~/wiringPi
./build
Then clone this repository into your ROS workspace(src folder):
git clone https://github.com/mdleiton/MPU9255.git
Compile it:
catkin_make
g offsetIMU.cpp -lwiringPi -o offsetIMU
Run a node:
./offsetIMU ofssetData.txt
source devel/setup.bash
rosrun MPU9255 MPU9255_node
Review the published data with:
rostopic echo /imu/data_raw
rostopic echo /imu/mag
install imu-tools:
sudo apt-get install ros-kinetic-imu-tools
run launch file:
source devel/setup.bash
roslaunch MPU9255 imu.launch
