H A DREADME.md1 # SFUD (Serial Flash Universal Driver) 串行 Flash 通用驱动库
7 … 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…
9 - 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
14 …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…
15 …Flash 不支持 SFDP 标准，SFUD 会查询配置文件 ( [`/sfud/inc/sfud_flash_def.h`](https://github.com/armink/SFUD/blo…
19 - 避免项目因 Flash 缺货、Flash 停产或产品扩容而带来的风险；
20 - 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…
21 - 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；
22 - 可以用来制作 Flash 编程器/烧写器
