Dear all, I am trying to install this toolbox [https://www.cgran.org/wiki/chancoding](https://www.cgran.org/wiki/chancoding). However, I am working on a windows environment GNU Radio, do anyone tried before or knows how can I get it installed on a GNU Radio? Thank you. Regards,Sun ---

That cgran page says “GNU Radio \>= 3.2.2”, which indicates it might be terribly outdated and would not work with 3.6.5 (it can’t work with 3.7); I don’t know if Nico has touched the code base since 2011, but I assume you’ll have to go great lengths to get it to work with current GNU Radio versions. Try the new gr-fec interface, now included in GNU Radio 3.7; it might suit your needs! Best Regards, Marcus ---

Hi Marcus, I’m using Encode CCSDS 27 and Decode CCSDS 27, but I don’t know how to handle with the requirement of “float” input in the Decode CCSDS 27. I tried to make a conversion block to convert bit to float (0 becomes -1 and 1 still becomes 1), but that did not work correctly. In the flow graph that I attached, the Btf\_Conversion block is to converts bits to floats and the Console Sink sink is just to print out what it receives.
