Re: [Discuss-gnuradio] Function Probe and OOT Blocks

[Kevin McQuiggin]

Hi David:

I'm a relative newbie myself, but I can say that I had this same issue.  I had a block with a static parameter that I wanted to be able to change dynamically at runtime.

I looked at the block's source code, and also at a block that had a dynamically adjustable parameter.

Basically, and with a little help from the list (Marcus Muller in particular) as I had to learn c++, I was able to use the code from the dynamic block as an example, and modify the static block to change the parameter to be dynamically changeable.  It all came down to at most a couple dozen lines of code.  The bigger challenge was learning about Gnuradio's architecture, to know what to do.

I would suggest a similar approach.  You will find the list members very helpful.  I'd also look at the guided tutorials, there are good examples there under "how to write a c++ block".

I will help if I can but alas, I am still quite a newbie, so others will be able to help much more efficiently!

​Hi guys,

I am familiar with using function probes to update values to blocks. This is straightforward with built in blocks like Multiply Const, where the input is underline in the GRC dialogue box.

How do I create a block, specifically a Python block, that allows me to update parameters in this fashion so that they are not fixed at runtime?

Regards,

David
