Dear all, I am still a GNU Radio beginner and at the moment I try to figure out how to develop an OOT block for GNU Radio. The tutorial explains how to do this and I have managed to create my first block. However, when it comes to the .yml file, I don't find all the information that I need. Is there a document that explains _in detail_ the block descriptions?
I have already looked at https://wiki.gnuradio.org/index.php/YAML_GRC but this page does not answer my question. I am looking for a possibility to create an enumeration of float values. Is this possible or are only integer values allowed (as in C/C++)? For example, in my block I need an option called "Guard interval" that has four possible values: 0.25, 0.125, 0.0625 and 0.03125. The corresponding labels would be 1/4, 1/8, 1/16 and 1/32. How can I do this? Thank you very much for your help! Kind regards, Ralf
