[Pcsclite-muscle] Driver development? (for rasp pi NXP PN512 spidev module)

[Frank Morgner]

Hi!

pcscd loads the driver and communicates to its C-like interface, see
http://pcsclite.alioth.debian.org/api/group__IFDHandler.html

So there is no way around a C-like interface. Although it's possible to
create a shared object file from python code (see
http://lmgtfy.com/?q=create+so+from+python ), I'm not sure if it's the
most practical path to go.

What you could also do is write a minimal IFDHandler and simply delegate
all calls to your python code. I did that using a very simple socket
interface, see
http://frankmorgner.github.io/vsmartcard/virtualsmartcard/api.html#creating-a-virtual-smart-card
You could also skip the IFDHandler part, reuse my driver and jump
directly to the socket communication...

Greets, Frank.

PS. Jan, you should also read encrypted mails ;-)
