Hi Adam,
Thanks for making this wrapper available. I have a Sparkfun 9d_razor
and I have upgraded the firmware using the .pde files in
imu_9drazor/src/SF9DOF_AHRS. I did this under Windows using the Arduino
IDE (version 0022) and the upload proceeded without errors.
Back on Linux with the IMU on port /dev/ttyUSB0 I followed the Wiki
instructions:
$ sudo ln -s /dev/ttyUSB0 /dev/imu
$ roslaunch imu_9drazor imu.launch
The launch proceeded without errors with the output:
process[imu_node-1]: started with pid [23276]
process[imu_msg_converter-2]: started with pid [23277]
However, when I echo the imu topic with "rostopic echo imu" there is no
data being published. Ditto for the topic imu/imu_raw. Both topics are
listed with "rostopic list".
One silly question: aside from having the IMU connected to the USB port,
do I also have to apply power to the white power connector? I did not
have to do this under Windows to see data via the firmware test application.
Any thoughts?
Thanks!
