30 /// \dir "Basic-dataflash-project"
31 ///
32 /// !!!Purpose
33 ///
34 /// The Basic Dataflash project will help new users get familiar with SPI interface
35 /// on Atmel's AT91 family of microcontrollers. This project gives you an AT45
36 /// Dataflash programming code so that can help develop your own SPI devices
37 /// applications with maximum efficiency.
38 ///
39 /// You can find following information depends on your needs:
40 /// - A Spi low level driver performs SPI device Initializes, data transfer and
41 /// receive. It can be used by upper SPI driver such as AT45 %dataflash.
42 /// - A Dataflash driver is based on top of the corresponding Spi driver.
43 /// It allow user to do operations with %dataflash in a unified way.
44 ///
45 /// !See also
46 /// - "spi-flash": Dataflash interface driver.
47 ///
48 /// !!!Requirements
49 ///
50 /// This package can be used with all Atmel evaluation kits that have SPI
51 /// interface and on-board or external Serialflash connected. The package runs at
52 /// SRAM or SDRAM, so SDRAM device is needed if you want to run this package in SDRAM.
53 ///
54 ///
55 /// !!!Description
56 ///
57 /// The demonstration program tests the dataflash present on the evaluation kit by
58 /// erasing and writing each one of its pages.
59 ///
60 /// !!!Usage
61 ///
62 /// -# Build the program and download it inside the evaluation board. Please
63 /// refer to the <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6224.pdf">SAM-BA User Guide</a>,
64 /// the <a href="http://www.atmel.com/dyn/resources/prod_documents/doc6310.pdf">GNU-Based Software Development</a>
65 /// application note or to the <a href="ftp://ftp.iar.se/WWWfiles/arm/Guides/EWARM_UserGuide.ENU.pdf">IAR EWARM User Guide</a>,
66 /// depending on your chosen solution.
67 /// -# On the computer, open and configure a terminal application
68 /// (e.g. HyperTerminal on Microsoft Windows) with these settings:
69 /// - 115200 bauds
70 /// - 8 bits of data
71 /// - No parity
72 /// - 1 stop bit
73 /// - No flow control
74 /// -# Start the application.
75 /// -# Upon startup, the application will output the following lines on the DBGU.
76 /// \code
77 /// -- Basic Dataflash Project xxx --
78 /// -- AT91xxxxxx-xx
79 /// -- Compiled: xxx xx xxxx xx:xx:xx --
80 /// -I- Initializing the SPI and AT45 drivers
81 /// -I- At45 enabled
82 /// -I- SPI interrupt enabled
83 /// -I- Waiting for a dataflash to be connected ...
84 /// \endcode
85 /// -# As soon as a dataflash is connected, the tests will start. Eventually,
86 /// the test result (pass or fail) will be output on the DBGU.

90 /// \unit
91 ///
92 /// !Purpose
93 ///
94 /// This file contains all the specific code for the basic-dataflash-project.
95 /// It tests the dataflash present on the evaluation kit by erasing and writing
96 /// each one of its pages
97 ///
98 /// !Contents
99 /// The code can be roughly broken down as follows:
100 /// - AT45 Dataflash write data function.
101 /// - AT45 Dataflash read data function.
102 /// - AT45 Dataflash erase function.
103 /// - Other AT45 functions (such as AT45_GetStatus())
104 /// - The main() function, which implements the program behavior.
105 /// - Initializes an AT45 instance and configures SPI chip select pin.
106 /// - Config SPI Interrupt Service Routine.
107 /// - Identifier the AT45 device connected to the evaluation kit.
108 /// - Test the dataflash by erasing and writing each one of its pages.
109 ///
110 /// !See also
111 /// - "spi-flash": Dataflash interface driver.
112 /// Please refer to the list of functions in the #Overview# tab of this unit
113 /// for more detailed information.
