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);

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 );
