STM32F4xx系列使用HAL库配置SPI-读写FLASH

SPI协议简介

SPI物理层特点

SPI协议层

QSPI协议简介

SPI框图

Flash写入与EEPROM有点相似，不同的是FLASH写入需要软件手动擦除，而EEPROM不用

SPI配置流程

1、初始化通讯使用的目标引脚及端口时钟

2、使能SPI外设的时钟

3、配置SPI外设的模式、地址、速率等参数并使能SPI外设

4、编写基本SPI按字节收发的函数

将片选信号拉低

查看数据发送完成标志，如果标志不存在

将数据写入SPI数据寄存器

5、编写对FLASH擦除及读写操作的函数

6、编写测试程序，对读写数据进行校验

HAL库读写串行FLASH(W125Q128)实验

flash 0xAB指令

flash 0x90指令

注意FLASH地址是24位的

这里直接放spi_flash的板级支持包，直接调用即可

可以直接将CubeMX生成的源文件spi.c和spi.h替换成下述文件即可

spi.c
