| * \page usart_iso7816 USART ISO7816 Example |
| * |
| * \section Purpose |
| * This example sends ISO 7816 commands to a smartcard connected to the |
| * evaluation kits on sam3s. |
| * |
| * \section Requirements |
| * This example can be used on sam3s evaluation kit. Please connect the |
| * smartcard contacts with following pins which could be easily wired from |
| * the board. |
| * - <b>SAM3S-EK -- SMARTCARD</b> |
| * - PA11 -- RST |
| * - TXD1(PA22) -- I/O |
| * - SCK1(PA23) -- CLK |
| * |
| * \section Description |
| * The iso7816 software provide in this examples is use to transform APDU |
| * commands to TPDU commands for the smart card. |
| * The iso7816 provide here is for the protocol T=0 only. |
| * The send and the receive of a character is made under polling. |
| * In the file ISO7816_Init is defined all pins of the card. User must have to |
| * change this pins according to his environment. |
| * The driver is compliant with CASE 1, 2, 3 of the ISO7816-4 specification. |
| * |
| * \section Usage |
| * -# Build the program and download it inside the evaluation board. Please |
| * refer to the <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6224.pdf">SAM-BA User Guide</a>, |
| * the <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6310.pdf">GNU-Based Software Development</a> |
| * application note or to the <a href="ftp://ftp.iar.se/WWWfiles/arm/Guides/EWARM_UserGuide.ENU.pdf">IAR EWARM User Guide</a>, |
| * depending on your chosen solution. |
| * -# On the computer, open and configure a terminal application (e.g. |
| * HyperTerminal on Microsoft Windows) with these settings: |
| * - 115200 bauds |
| * - 8 data bits |
| * - No parity |
| * - 1 stop bit |
| * - No flow control |
| * -# Connect the card reader to sam3s-ek board: |
| * <table border="1" cellpadding="2" cellspacing="0"> |
| * <tr><td>C1: Vcc: 7816_3V5V </td><td> C5: Gnd</td> <td> C4: RFU</td></tr> |
| * <tr><td> C2: Reset: 7816_RST</td> <td> C6: Vpp</td> <td> C8: RFU</td></tr> |
| * <tr><td> C3: Clock: 7816_CLK</td> <td> C7: 7816_IO</td> </tr> |
| * </table> |
| * If necessary,another pin must be connected on the card reader for detecting the |
| * insertion and removal: 7816_IRQ. |
| * On Atmel boards, all this pins can be easily connecting with jumpers. |
| * -# Start the application. The following traces shall appear on the terminal: |
| * \code |
| * -- USART ISO7816 Example xxx -- |
| * -- xxxxxx-xx |
| * -- Compiled: xxx xx xxxx xx:xx:xx -- |
| * Display the ATR |
| * \endcode |
