GX5-10 compatibility #5
Comments
|
Ryan, Have you tried running the driver (without commenting out any code) using the microstrain_25.launch file? In the launch file you can set the ROSCONSOLE_CONFIG_FILE variable so that the debug ROS log information is set to the screen - that might help. If you can send me the log file from that test I may be able to tell what is going on. The -10 sensor will need to have the publish_imu code, that is the only part of the code that will apply to the -10. With the publish_imu parameter set to true, the driver will read the following messages...
which are used to populate the /imu/data topic. The datasheet for the -10 suggests the it doesn't report the quaternion data, only the accelerometer and gyro data. This will likely cause the driver to hang, but it is a good first step. I can make a quick modification to try and support the -10 if you are will to test with the hardware and send logs. Thank you! |

Sure thing. I've enclosed the output running the driver as is with the It hangs at "Setting the AHRS message format" which I suspect is line 252 where the message format is being set with 3 entries including Quaternions. Happy to try any modifications! I'll be working on this all day. ryan@snorlax:~/catkin_ws_microstrain$ roslaunch microstrain_3dm_gx5_45 microstrain_25.launch

After commenting the declination and filter code, it works! Specifically, lines: |

Ryan, That is great. I added a few more parameters so that the driver can support the -10 (in addition to the -25, -35 and -45). I also added a new -10 specific launch file for you to try. These changes are in the "10-dev" branch. Could you give it a try? Would be nice if we can merge your changes back into the master. Nice job! |
|
There are few issues that persist.
Adding more one-off settings seems inefficient. I'm not too familiar with ROS node architecture, but can the functionality be modularized into different types within the same package? It'd further be nice to not obscure the compatibility range under the "gx5-45" package name. I'd be happy to contribute if you wanted to push down a path like that. |

Ryan,
It would be great if you could send a pull request. I can test it with the
-45 to make sure we haven't broke anything.
Yes, the name of the package should change. When I wrote it, it was
specific to the -45 sensor, which is what we use, but others have been able
to get it to work with the -35, -25 and now the -10. I should change the
name to reflect the compatibility.

- data_stream_format_num_entries needs to be set to 2 (Line 258).
- It hangs on lines 446 and 460.

Awesome, I'll work on the pull. May take a few weeks (work on this is mostly reserved to the weekends). Thanks for your informative and speedy replies! Really appreciate the help! |
I'm building compatibility for the GX5-10 into the driver. My progress thus far:
The GX5-10 is connected through an RS232-to-USB connector on
/dev/ttyUSB0. It was necessary to add the Linux user to thedialoutgroup so that the driver could connect over that port.The GX5-10 does not have AHRS or filtering features, so for starters, I commented out the portions of
publish_imucode that configured the AHRS as well as all the filter related functionality.Using
microstrain_25.launch, the driver progresses to spinning up the IMU. This is confirmed by log output from the driver as well as the indicator lights on the IMU. Unfortunately, no messages are published over/imu/data.Any thoughts? Is there a separate data stream that needs be started since there is no AHRS data stream?
Thanks for your help!
