[SFUD](https://github.com/armink/SFUD) 是一款开源的串行 SPI Flash 通用驱动库。由于现有市面的串行 Flash 种类居多，各个 Flash 的规格及命令存在差异， SFUD 就是为了解决这些 Flash 的差异现状而设计，让我们的产品能够支持不同品牌及规格的 Flash，提高了涉及到 Flash 功能的软件的可重用性及可扩展性，同时也可以规避 Flash 缺货或停产给产品所带来的风险。
- 主要特点：面向对象（同时支持多个 Flash 对象）、可灵活裁剪、扩展性强、支持 4 字节地址
- 主要特点：支持 SPI/QSPI 接口、面向对象（同时支持多个 Flash 对象）、可灵活裁剪、扩展性强、支持 4 字节地址
- 资源占用
- 标准占用：RAM:0.2KB ROM:5.5KB
- 最小占用：RAM:0.1KB ROM:3.6KB
- 设计思路：这里要首先跟大家介绍一个标准： **SFDP** ，它是 JEDEC （固态技术协会）制定的串行 Flash 功能的参数表标准，最新版 V1.6B （[点击这里查看](https://www.jedec.org/standards-documents/docs/jesd216b)）。该标准规定了，每个 Flash 中会存在一个参数表，该表中会存放 Flash 容量、写粒度、擦除命令、地址模式等 Flash 规格参数。目前，除了部分厂家旧款 Flash 型号会不支持该标准，其他绝大多数新出厂的 Flash 均已支持 SFDP 标准。所以该库在初始化时会优先读取 SFDP 表参数，如果该 Flash 不支持 SFDP，则查询配置文件 ( [`/sfud/inc/sfud_flash_def.h`](https://github.com/armink/SFUD/blob/master/sfud/inc/sfud_flash_def.h#L110-L122) ) 中提供的 **Flash 参数信息表** 中是否支持该款 Flash。如果不支持，则可以在配置文件中添加该款 Flash 的参数信息（添加方法详细见 [2.5 添加库目前不支持的 Flash](#25-添加库目前不支持的-flash)）。获取到了 Flash 的规格参数后，就可以实现对 Flash 的全部操作。

#### 2.2.3 获取 Flash 设备对象
#### 2.2.3 使能快速读模式（仅当 SFUD 开启 QSPI 模式后可用）
当 SFUD 开启 QSPI 模式后，SFUD 中的 Flash 驱动支持使用 QSPI 总线进行通信。相比传统的 SPI 模式，使用 QSPI 能够加速 Flash 数据的读取，但当数据需要写入时，由于 Flash 本身的数据写入速度慢于 SPI 传输速度，所以 QSPI 模式下的数据写入速度提升并不明显。
所以 SFUD 对于 QSPI 模式的支持仅限于快速读命令。通过该函数可以配置 Flash 所使用的 QSPI 总线的实际支持的数据线最大宽度，例如：1 线（默认值，即传统的 SPI 模式）、2 线、4 线。
设置后，SFUD 会去结合当前设定的 QSPI 总线数据线宽度，去 [QSPI Flash 扩展信息表](https://github.com/armink/SFUD/blob/069d2b409ec239f84d675b2c3d37894e908829e6/sfud/inc/sfud_flash_def.h#L149-L177) 中匹配最合适的、速度最快的快速读命令，之后用户在调用 sfud_read() 时，会使用 QSPI 模式的传输函数发送该命令。
```C
sfud_err sfud_qspi_fast_read_enable(sfud_flash *flash, uint8_t data_line_width)
```

#### 2.2.4 获取 Flash 设备对象
在 SFUD 配置文件中会定义 Flash 设备表，负责存放所有将要使用的 Flash 设备对象，所以 SFUD 支持多个 Flash 设备同时驱动。设备表的配置在 `/sfud/inc/sfud_cfg.h` 中 `SFUD_FLASH_DEVICE_TABLE` 宏定义，详细配置方法参照 [2.3 配置方法 Flash](#23-配置方法)）。本方法通过 Flash 设备位于设备表中索引值来返回 Flash 设备对象，超出设备表范围返回 `NULL` 。
