FLASH是常用的一种非易失存储单元W25QXX系列Flash有不同容量的型号如W25Q64的容量为64Mbit也就是8MByte。这里介绍STM32CUBEIDE开发平台HAL库Quad SPI总线实现FATS文件操作W25Q各型号FLASH的例程。非FATS直接Quad SPI操作W25QXX FLASH的方式见《STM32存储左右互搏 QSPI总线读写FLASH W25QXX》
W25QXX介绍
W25QXX的SOIC封装如下所示在采用QUAL SPI而不是SPI时管脚定义为 即由片选(/CS), 时钟(CLK), 双向4根输入输出线(IO0, IO1, IO2, IO3)组成6线QSPI信号接口。VCC和GND提供电源和接地连接。
例程采用STM32H750VBT6芯片, FLASH可以选择为8/16/32/64/128/256/512/1024 Mbit的W25Q型号。
STM32工程配置
首先建立基本工程并设置时钟 注意QSPI时钟在单独的时钟树支上 QSPI接口可以配置为两个Bank并行协同存储扩展也可以配置为单个Bank并且可以由4线数据线模式降级为单线/双线数据线模式。这里对于单个Flash选择一个bank配置 注意QSPI的片选信号是硬件自动控制和SPI可以采用软件代码控制不同所以不必单独指定一个GPIO作为片选 不用DMA 配置FATS参数 配置串口UART1作为命令输入和打印输出接口 不用DMA: 保存并生成初始工程代码
STM32工程代码
UART串口printf打印输出实现参考STM32 UART串口printf函数应用及浮点打印代码空间节省 (HAL)
