Any Samples for Interfacing Smart Card with At91sam7x

Postby moh.kermani » Wed Jun 12, 2013 2:32 pm

Hi All,
It's two weeks that I'm trying to interface A Java Card to at91sam7x256 on ChibiOS, but there's no hope.It seems impossible and there's no sample code/project on the Web. Can Anyone help me?
This is Serial Config:

Code: Select all

static const SerialConfig smartcard_config = { 9600, AT91C_US_USMODE_ISO7816_0
      | AT91C_US_CLKS_CLOCK | AT91C_US_NBSTOP_1_BIT | AT91C_US_PAR_EVEN
      | AT91C_US_CHRL_8_BITS | AT91C_US_OVER |AT91C_US_CKLO};


Note that card is java card, T0 and baud rate is 9600.

Do you receive the ATR sequence or nothing at all? I would also verify possible connections problem, card clocks, card power, card reset sequence etc.

Thanks Giovanni,
Forum does not send email updates and I thought no one knows.
I do not receive ATR sequence also. I've directly connected smart card pins to the Chip, as it is told in datasheet.

Hi,

You have to subscribe to the forums you are interested in, then you will receive emails.

Does the card actually transmit the ATR sequence after the reset? Check with an oscilloscope or a logic analyzer.
