+/// Different tests can be done with the Windows(c) software Smart Access(c).
+/// Smart Access: a powerful scripting tool to write sequences of commands. +/// +/// !!!Usage +/// +/// -# Install Smart Access(c) software. +/// -# Build the program and download it inside the evaluation board. Please +/// refer to the SAM-BA User Guide, +/// the GNU-Based Software Development +/// application note or to the IAR EWARM User Guide, +/// 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 +/// - Hardware flow control (RTS/CTS) +/// -# Start the application. The following traces shall appear on the terminal: +/// \code +/// -- USB Device CCID Project xxx -- +/// -- AT91xxxxxx-xx +/// -- Compiled: xxx xx xxxx xx:xx:xx -- +/// \endcode +/// -# Connect the USB cable to the board. Traces should start to appear on the terminal.
+/// If this is the first time the device is connected to the PC, +/// the operating system may take some time to install it. +/// -# The device is enumerated as a Smart Card Device implementing CCID class.
+/// -# The host use the CCID device driver (usbccid.sys) as the functionnal driver. +/// -# Launch Smart Access and connect it to the Card Reader Atmel.
