I want to use dynamic reconfiguration to modify an array in a ROS node, but I didn't found any example of how to modify the .cfg file on the web.

I want this line: gen.add("int_param", int_t, 0, "An Integer parameter", 50, 0, 100)

in something kind of: gen.add("int_array", int_t[2], 0, "An Integer array", [50 20], [0 0], [100 100])

Can someone help? Thanks!

According to this Tutorial, arrays are not allowed:

type - defines the type of value stored, and can be any of int_t, double_t, str_t, or bool_t

Maybe you can achieve what you want by using the group type.
