# SFUD (Serial Flash Universal Driver) 串行 Flash 通用驱动库
---
## 0、SFUD 是什么
[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
- 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、写粗粒度、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` ) 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。
## 1、为什么选择 SFUD
- 避免项目因 Flash 缺货、Flash 停产或产品扩容而带来的风险;
- 越来越多的项目将固件存储到串行 Flash 中,例如:ESP8266 的固件、主板中的 BIOS 及其他常见电子产品中的固件等等,但是各种 Flash 规格及命令不统一。使用 SFUD 即可避免,在相同功能的软件平台基础下,无法适配不同 Flash 种类的硬件平台的问题,提高软件的可重用性;
- 简化软件流程,降低开发难度。现在只需要配置好 SPI 通信,即可畅快的开始玩串行 Flash 了;
- 可以用来制作 Flash 编程器/烧写器
## 2、SFUD 如何使用
### 2.1 已支持 Flash
下表为所有在 Demo 平台上进行过真机测试的 Flash。目前 SFUD 提供的 **Flash 参数信息表** 只包括下表中 **不支持** SFDP 标准的 Flash,其他不支持 SFDP 标准的 Flash 需要大家以后 **共同来完善和维护** **([Github](https://github.com/armink/SFUD)|[OSChina](http://git.oschina.net/armink/SFUD)|[Coding](https://coding.net/u/armink/p/SFUD/git))** 。如果觉得这个开源项目很赞,可以点击 [项目主页](https://github.com/armink/SFUD) 右上角的 **Star** ,同时把它推荐给更多有需要的朋友。
