That is one problem I had in the beginning, too. The
answer to your question is simple. Carlos driver does
only support one of five different mainstream protocol
types, T=0. T=0 is used for processor cards, like
GSM-SIM-Cards for mobile telefones. T=0 is one
of two asynchronous protocols, the other is called
T=1. Apart from this protocol family there is those of
the synchronous protocols, which are used for memory
cards. It consists of three members: 2-wire, 3-wire
and I2C.
I would guess that you have tried to use the memory
card that was delivered with the reader with Carlos
routines. That would be the same failure I made some
months ago. This wonīt work. You would need a driver
that supports the protocol that the card speaks that
you want to use. To determine which protocol a card
speaks you can take the "smartcard explorer" from the
Towitoko CD.
For the i2c-protocol there is another library written
by the "Towitoko Driver Project". For more information
on that you should have a look at
http://www.penguinteam.org/towitoko. Matthias Bruestle
wrote a library that supports every Chipdrive family
reader beside others and can handle synchronous
protocols iirc. But I couldnīt find the right URL. He
is reading this list, maybe he tells you :)
I wrote my own lib that implements only T=1. There has
been one release only yet and it had a lot of bugs.
I didnīt had the time to finish work on the next
version, especially on the documentation.
Hope that helps a bit.
cu, Mike
