概述
初始化和去原始化功能：
uint8_t SPI_FlashEx_Init (SPI_Flash_BankTypeDef *_flashBank);操作功能：
/* :::::::::::::::::::: Flash Erase :::::::::::::::::::: */
uint8_t SPI_FlashEx_ChipErase (SPI_Flash_BankTypeDef *_flashBank);
uint8_t SPI_FlashEx_SectorErase (SPI_Flash_BankTypeDef *_flashBank, uint32_t _sector);
uint8_t SPI_FlashEx_BlockErase (SPI_Flash_BankTypeDef *_flashBank, uint32_t _block);
/* :::::::::::::::::::: Flash Write :::::::::::::::::::: */
uint8_t SPI_FlashEx_Write (SPI_Flash_BankTypeDef *_flashBank, uint8_t _data, uint32_t _address);
uint8_t SPI_FlashEx_PageWrite (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_pData, uint32_t _page, uint32_t _offset, uint32_t _size);
uint8_t SPI_FlashEx_SectorWrite (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_pData, uint32_t _sector, uint32_t _offset, uint32_t _size);
uint8_t SPI_FlashEx_BlockWrite (SPI_Flash_BankTypeDef *_flashBank, uint8_t * _pData, uint32_t _block, uint32_t _offset, uint32_t _size);
uint8_t SPI_FlashEx_BurstWrite (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_pData, uint32_t _address, uint32_t _size);
/* :::::::::::::::::::: Flash Read ::::::::::::::::::::: */
uint8_t SPI_FlashEx_Read (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_data, uint32_t _address);
uint8_t SPI_FlashEx_PageRead (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_pData, uint32_t _page, uint32_t _offset, uint32_t _size);
uint8_t SPI_FlashEx_SectorRead (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_pData, uint32_t _sector, uint32_t _offset, uint32_t _size);
uint8_t SPI_FlashEx_BlockRead (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_pData, uint32_t _block, uint32_t _offset, uint32_t _size);
uint8_t SPI_FlashEx_BurstRead (SPI_Flash_BankTypeDef *_flashBank, uint8_t *_pData, uint32_t _address, uint32_t _size);

None 指导
该库可用如下：
1。添加SPI Flash库作为基础库并进行配置
2。在项目中添加SPI Flash Ex tension库标头和源文件
3。在“ spi_flash_ex_conf.h”中配置库，例如：
/* ----------- Configuration ------------ */
# define _SPI_FLASH_EX_USE_LAST_WRITE_ADD 4。创建闪存对象的数组，设置特定的GPIO，例如：
- 例子：
SPI_Flash_TypeDef MainFlashList[ 3 ]; MainFlashList[ 0 ].CS_GPIO_Port = 0 ; MainFlashList[ 0 ].CS_GPIO_Pin = ( 1 << 2 ); MainFlashList[ 1 ].CS_GPIO_Port = 0 ; MainFlashList[ 1 ].CS_GPIO_Pin = ( 1 << 3 ); MainFlashList[ 2 ].CS_GPIO_Port = 0 ; MainFlashList[ 2 ].CS_GPIO_Pin = ( 1 << 4 );
5。创建闪存库对象，设置flashlist，numberofchip并初始化它，例如：
初始化器：
SPI_FlashEx_Init (SPI_Flash_BankTypeDef *_flashBank);参数：
- _flashbank：指向Flash Bank结构的指针
例子：
Code of step 4 ... SPI_Flash_BankTypeDef FlashBank; FlashBank.FlashList = MainFlashList; FlashBank.NumberOfChip = 3 ; SPI_FlashEx_Init (&FlashBank);
6。使用闪存扩展操作功能
SPI_FlashEx_ChipErase (&FlashBank);
SPI_FlashEx_SectorWrite (&FlashBank, Tx_Buf, 0 , 10 , 44 );例子
