打开hal\_flash.h文件，接口列表如下： * 驱动程序初始化： ``` void hal_flash_init(void); ``` * FLASH 读操作： ``` int hal_flash_read(uint32_t address, uint16_t offset, uint8_t *buf, uint16_t len); ``` * FLASH 写操作： ``` int hal_flash_write(uint32_t address, uint16_t offset, const uint8_t *buf, uint16_t len); ``` * FLASH 写操作（双buffer）： ``` int hal_flash_write2(uint32_t address, uint16_t offset, const uint8_t *buf1, uint16_t len1, const uint8_t *buf2, uint16_t len2); ``` * FLASH 擦除操作： ``` int hal_flash_erase(uint8_t page); ``` <br/>
