- *
- * User code should include this file, which will in turn include the correct dataflash driver header file for
- * the currently selected board.
- *
- * If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/Dataflash.h file in the user project

- * \section Sec_Dependencies Module Source Dependencies
- * The following files must be built with any user project that uses this module:
- * - None
- *
- * \section Sec_ModDescription Module Description
- * Dataflash driver. This module provides an easy to use interface for the Dataflash ICs located on many boards,
- * for the storage of large amounts of data into the Dataflash's non-volatile memory.
- *
- * If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/Dataflash.h file in the user project
- * directory. Otherwise, it will include the appropriate built in board driver header file.
- *
- * For possible \c BOARD makefile values, see \ref Group_BoardTypes.
- *
- * \section Sec_ExampleUsage Example Usage
- * The following snippet is an example of how this module may be used within a typical
- * application.
- *
- * \code
- * // Initialize the SPI and board Dataflash drivers before first use
- * SPI_Init(SPI_SPEED_FCPU_DIV_2 | SPI_ORDER_MSB_FIRST | SPI_SCK_LEAD_FALLING |
- * SPI_SAMPLE_TRAILING | SPI_MODE_MASTER);
- * Dataflash_Init();
- *
- * uint8_t WriteBuffer[DATAFLASH_PAGE_SIZE];
- * uint8_t ReadBuffer[DATAFLASH_PAGE_SIZE];
- *
- * // Fill page write buffer with a repeating pattern
- * for (uint16_t i = 0; i < DATAFLASH_PAGE_SIZE; i++)
- * WriteBuffer[i] = (i & 0xFF);
- *
- * // Must select the chip of interest first before operating on it
- * Dataflash_SelectChip(DATAFLASH_CHIP1);
- *
- * // Write to the Dataflash's first internal memory buffer
- * printf("Writing data to first dataflash buffer:\r\n");
- * Dataflash_SendByte(DF_CMD_BUFF1WRITE);
- * Dataflash_SendAddressBytes(0, 0);
- *
- * for (uint16_t i = 0; i < DATAFLASH_PAGE_SIZE; i++)
- * Dataflash_SendByte(WriteBuffer[i]);
- *
- * // Commit the Dataflash's first memory buffer to the non-volatile FLASH memory
- * printf("Committing page to non-volatile memory page index 5:\r\n");
- * Dataflash_SendByte(DF_CMD_BUFF1TOMAINMEMWITHERASE);
- * Dataflash_SendAddressBytes(5, 0);
- * Dataflash_WaitWhileBusy();
- *
- * // Read the page from non-volatile FLASH memory into the Dataflash's second memory buffer
- * printf("Reading data into second dataflash buffer:\r\n");
- * Dataflash_SendByte(DF_CMD_MAINMEMTOBUFF2);
- * Dataflash_SendAddressBytes(5, 0);
- * Dataflash_WaitWhileBusy();
- *
- * // Read the Dataflash's second internal memory buffer
- * Dataflash_SendByte(DF_CMD_BUFF2READ);
- * Dataflash_SendAddressBytes(0, 0);
- *
- * for (uint16_t i = 0; i < DATAFLASH_PAGE_SIZE; i++)
