Using block argument

GNU Radio
1

hi,
I have created with gr_modtool a block in which is assigned as argument
a
float, “threshold”.

In the file _impl.h I have defined another variable called “d_threshold”
in
the private sector, while in the constructor of the file _impl.cc
the assignment d_threshold=threshold;

The problem is that, the constructor make the assignment only one time,
but
if I want to change the value of the argument at run time,
in which way I need to assign this variable “threshold”???

thanks,
Simone

Hi Simone,

I thing you have implemented the setter (e.g set_threshold(float) ), if
so,
you must specify it in the corresponding .xml file in the grc directory,
you can do that using set_threshold($threshold)

Regards,
Mohamed
