How to store data receieved from UM7
dear,
i run a UM7 drivers but i'm not able to see inertial data (i'm able to see only messages like received packet XY without data or sending command zero gyroscopes).
Do you have some solution how to show inertial data (from accelerometers and gyroscopes?)
Thank you for your responce
Edit: thank you for your response. There is a manual how to show data for other users. I hope it should be useful.
install ROS + other features
sudo su
roscore
second terminal
- sudo su
- cd /root/catkin_ws (or place where you have a catkin workspace)
- source devel/setup.bash
- rosrun um7 um7_driver _port:=/dev/ttyAMA0
A) show data in RVIZ
- Third console
- rosrun rviz rviz (you need rviz_imu_plugin)
- add module IMU
- fixed frame : imu_link 13 in module IMU fill topic /imu/data
- rviz should show data from IMU
B) show RAW data in console
- third console
- sudo su
- rostopic echo /imu/data (or show another type using rostopic list)
Why are you running things in a
sudo susession? That should not be necessary (and is often very much undesirable).Yeah sure, it is not necessary for all users. In my case i installed ros under root and without sudo session i am not able to run ros.
