I sort-of thought that the .h files included in studio were automatically generated from the ARM-standardized CMSIS ".svd" files.

But in fooling around with parsing the .svd files, I don't see how this can be the case:

  1. The .svd files don't provide the division into the components/*.h  (I guess that they COULD...)
  2. PORTGROUP isn't mentioned anywhere in (say) ATSAMD21G18A.svd
  3. the elements of PORT are dimensioned "oddly" - it seems that registers are accessed via PORT.DIR[portnum] and similar instead of PORTS[portnum].dir, or something like that...

 

Am I missing something?

 

(The goal is essentially to generate assembly-style definition files instead of C .h files...)

All files including the svd and header files are generally generated from the atdf files.

Hmm.  I'm still not sure where "PortGroup" comes from...
There's no PortGroup in the .atdf, and I can't understand how "something" decides to concatenate Port and Group names when it doesn't do so for most of the devices...
