   OP here, yes, I'm not going mad.  There are major changes between the   
   i.6.x and 2.x versions of python3-libgpiod.  The trouble is that   
   finding out about it all is very difficult because there are so many   
   different python wrappers for gpiod and this makes searching very   
   frustrating.   
      
   The best I've found so far is the 'source':-   
       https://github.com/brgl/libgpiod/blob/master/bindings/python/README.md   
      
   It has some Python examples but the coding style is very odd and makes   
   it difficult to follow what's going on IMHO.
