stm32L475 QSPI 裸机 Demo

---

1、简介

Demo 提供的工程是基于 STM32L475 的，通过 QSPI 外设连接 W25Q128B FLASH，Demo 里的 QSPI 读取数据使用的是四线快读指令 - Fast Read Quad I/O（0xEB）。

通过 Src\main.c 的 void sfud_demo(uint32_t addr, size_t size, uint8_t *data) 方法来演示并测试第一个 Flash 设备的擦除、写入及读取功能，最后会将写入后数据读取出来，与写入前的数据进行对比，如果一致，则测试通过。

1.1、使用方法

• 1、打开电脑的终端与Demo的串口1进行连接，串口配置 115200 8 1 N
• 2、下载并运行 Demo ，此时可查看到类似如下的打印日志信息
