宏：
None 指导
该库可用如下：
1。配置MCU SPI并初始化它
2。在项目中添加库标头和源文件
3。例如，在“ spi_flash_conf.h”中配置库：
/* ---------- Controller Series --------- */
# define _LPC17XX
/* ------ Required Driver.Library ------- */
# include " lpc_spi_ex.h "
# include " lpc_gpio_ex.h "
/* ----------- Configuration ------------ */
/* ............ SPI ............ */
# define _SPI_FLASH_PERIPHERAL LPC_SPI
# define _SPI_FLASH_TIMEOUT 100
/* ............ RTOS ........... */
# define _SPI_FLASH_USE_RTOS 0
/* ..... Flash manufacturer .... */
# define _SPI_FLASH_WINBOND 4。创建闪存对象，设置特定的GPIO并初始化它，例如：
初始化器：
SPI_Flash_Init (SPI_Flash_TypeDef *_flash);参数：
- _flash：指向Flash Struct的指针
例子：
SPI_Flash_TypeDef Flash1; Flash1.CS_GPIO_Port = 0 ; Flash1.CS_GPIO_Pin = ( 1 << 16 ); SPI_Flash_Init (&Flash1);
5。使用闪存操作功能
SPI_Flash_ChipErase (&Flash1);
SPI_Flash_SectorWrite (&Flash1, Tx_Buf, 0 , 10 , 44 );例子
示例1：与LPC1768初始化并使用外部闪存
# include " lpc17xx.h "
# include " lpc17xx_gpio.h "
# include " lpc17xx_spi.h "
# include " lpc17xx_libcfg.h "

# include " lpc_spi_ex.h "
# include " spi_flash.h "

uint8_t Tx_Buf[ 44 ] = " Hello from master!, this is an test program \n " ;
uint8_t Rx_Buf[ 50 ];

SPI_Init (LPC_SPI, &SPI_ConfigStruct);
/* --------- Wait to init --------- */
SPI_Delay ( 1 );
/* ~~~~~~~~~~~~~~~~~~ Flash Example ~~~~~~~~~~~~~~~~~ */
/* --------- Setup Flash ---------- */

SPI_Flash_TypeDef Flash2;
SPI_Flash_TypeDef Flash3;

SPI_Flash_Init (&Flash2);
SPI_Flash_Init (&Flash3);
SPI_Flash_ChipErase (&Flash1);
SPI_Flash_ChipErase (&Flash2);
SPI_Flash_ChipErase (&Flash3);
