Program to simulate seven segment display in atmel studio
After looking at Atmel Studio I couldn't see any apparent way to add any form of custom debugging plug-ins so I lodged a support request. As well as pre-written ones I also asked about the possibility of writing custom plug-ins and here is the verbatim response I received:


  Unfortunately, we do not have a custom debugging plug- in for the
  display of I/O registers as of now. For the list of available
  extensions with Atmel studio 6, please visit the below link:

  Hope this helps. Please get back to us in case of further queries.


While the question of whether it is possible to develop custom extensions that can read the I/O registers doesn't seem to have been addressed with 100% clarity looking through the list of gallery extensions I can't see anything that performs any similar functions.
