Dynamic Reconfigure Parameter Limits lower than Hardware Limits #100

I am trying to set the frame rate on my Point Grey Chameleon 3. The dynamic reconfigure has a max value of 100. I see that this is set in the PointGrey.cfg file. However, the camera itself is capable of higher frame rates.

I have installed the camera driver from apt: sudo apt-get install ros-kinetic-pointgrey-camera-driver

Is there a way for me to modify the PointGrey.cfg file somewhere? I assume with my install method that it is all packaged up in a binary file and not changeable. Is there a way to override the default PointGrey.cfg file with a custom one? Can I point the Nodelet at a new .cfg file? Maybe in the launch file?

I have a custom launch file already where I set various parameters for the Nodelet. I generated this launch file by copying the camera.launch file from this github page and adding parameters. Is there a line I could add in here to tell the Nodelet to use a custom .cfg file?

I have tried installing from source so that I can modify the PointGrey.cfg file, but I have not had any luck getting that to work either. Are there instructions somewhere that could help me install this from source?

Building this package from source should be the same as building any other ROS package. What issues are you having?

In any case, please feel free to send a PR that expands the limits. This package is due for a new release soon anyways.

I actually did get it installed from source now. I was doing it wrong. I was able to change that .cfg file and get higher frame rates. Thanks.

Please send a PR with the limits that work for your camera, so that the debs can be made to work for you and future users for your hardware.
