This example demonstrates the logic used to filter for a specific node on the bus, and uses the ParameterGetSet API to update a specific parameter ID at runtime. It publishes and subscribes the ps_parameters_msg, and checks and then updates the coordinate frame identifier, specifically for a video device node.


Packages: libglib2.0-dev

To install on Ubuntu:

sudo apt-get install libglib2.0-dev

Building and running the node

$ cd ParameterGetSet 
$ mkdir build && cd build
$ cmake ..
$ make
$ ./polysync-parameter-get-set-cpp
