1.什么是SPI控制器
SPI 是英语Serial Peripheral interface的缩写，顾名思义就是串行外围设备接
口。是Motorola首先在其MC68HCXX系列处理器上定义的。
SPI，是一种
高速的，全双工，同步的通信总线
（因为带有SCL同步时钟），并且
在芯片的管脚上只占用四根线，节约了芯片的管脚，同时也在PCB的布局上节省
了空间。
主要应用在 处理器 与 EEPROM、FLASH、实时时钟、AD转换器等外设之间的
数据传输或通信。已知的SPI器件传输速度可达到50Mbp
2. SPI控制器
1. STM32F4XX有3个SPI控制器，分别是SPI1/2/3。 （控制三个从机）
2. SPI1控制器挂载在APB2总线上。
3. SPI2和SPI3挂载在APB1总线上。一般使用GPIO引脚去模拟SPI时序，完成 SPI驱动的实现。至于STM32内置的SPI控制器，其最终也是为了实现SPI的读写 操作时序。
3. 数据传输逻辑
1. 主机和从机都包含一个串行移位寄存器，主机通过向它的SPI串行寄存器写入一个字节发起一次传输。
2. 寄存器通过MOSI信号线将字节传送给从机，从机也将自己的移位寄存器中的内容通过MISO信号线 返回给主机。这样两个移位寄存器中的内容就被交换了。从机的写操作和读操作时同步完成的，因 此SPI成为一个很有效的协议。
3.MOSI及MISO数据线在SCK的每个时钟周期传输一位数据，且数据输入输出是同时进行的。SPI每次数据传输可以8位或16位为单位，每次传输的单位数不受限制。
4. SPI接口数据信号线
1. SPI接口经常被称为4线串行总线，以主/从方 式工作，数据传输过程由主机初始化。其使用 的4条信号线分别为:
1)SCLK:串行时钟，同步数据传输由主机输出;
2)MOSI:主机输出从机输入数据线;
3)MISO:主机输入从机输出数据线;
4) SS:片选线，低电平有效，由主机输出。
2. 在SPI总线上，某一时刻可以出现多个从机，但 只能存在一个主机，主机通过片选线确定通信的
从机。这就要求从机的MISO口具有三态特性， 使得该口线在器件未被选通时表现为高阻抗
。
5. SPI多种通信方式
选中的设备在发送数据时，待发送的数据在SCLK信号的作用下，以bit 为单位依次通过MOSI从主
设备发送给从设备; 接收数据时, 在时钟信号SCLK的作用下，数据以bit为单位依次从MISO引脚接
收从设备发给主设备的数据;SPI通信协议规定,
先发送高位，后发送低位。
6. SPI和I2C比较
1. 这两种协议在鲁棒性方面都比较好。I²C之所以优雅，是因为它在极简的基础架构（两线SDA/SCL） 上提供了非常先进的功能，例如自动多主机冲突处理和内置地址管理。但是它相对却非常复杂，在 性能上或许有所欠缺。
2. 另一方面，SPI非常易于理解和实施，并且为扩展提供了很大的灵活性。SPI的优雅之处在于简单性。 SPI应该被视为构建用于IC之间通信的自定义协议栈的良好接口。因此，尽管使用SPI可能需要做更多的工作，但可以提供更高的数据传输性能和灵活的自由度。
3. 如果一定要比较，则SPI和I2C都为低速设备的通信提供了良好的接口支持，但是SPI更适合点对点传 输数据流的应用，而I²C则更适合于多主机“寄存器访问”应用。
4.正确使用这两种协议可提供相同级别的鲁棒性，芯片厂商对两种接口都广泛支持。市面上提供了大 量的外围芯片，比如 EEPROM，ADC，DAC，RTC，微控制器，传感器，LCD控制器，这些芯片 主要提供I²C，SPI或同时支持这2个接口。
7. SPI 信号讲解
1. 起始信号:NSS信号线由高变低，是SPI通讯的起始信号(CPOL=1低电平有效) NSS 是每个从机各自独占的信号线，当从机检在自己的 NSS 线检测到起始信 号后，就知道自己被主机选中了，开始准备与主机通讯.
2. 结束信号:NSS信号由低变高，是SPI通讯的停止信号,从机的选中状态被取消。
8. SPI数据传输原理与时序图
9.SPI 四种工作模式
1. SPI 总线四种工作方式 SPI 模块为了和外设进行数据交换，根据外设工作要求，其输出串
行同步时钟极性和相位可以进行配置，时钟极性（
CPOL
）对传输协议没有重大的影响。
如果
CPOL=0，串行同步时钟的空闲状态为低电平
；如果
CPOL=1，串行同步时钟的空
闲状态为高电平
。时钟相位（CPHA）能够配置用于选择两种不同的传输协议之一进行数
据传输。如果
CPHA=0在串行同步时钟的
第一个跳变沿
（上升或下降）数据被采样
；如
果
CPHA=1，在串行同步时钟的
第二个跳变沿
（上升或下降）数据被采样
。SPI 主模块
和与之通信的外设备时钟相位和极性应该一致。
一般情况是CPOL=1,CPHA=1
2.
四种工作模式
(
总结）
（1）时钟极性（CPOL）：
<1>CPOL=0，串行同步时钟的空闲状态为低电平；
<2>CPOL=1，串行同步时钟的空闲状态为高电平;
（2）时钟相位（CPHA）：
<1>CPHA=0，在串行同步时钟的第一个跳变沿(上升或下降)数据被采样；
<2>CPHA=1，在串行同步时钟的第二个跳变沿(上升或下降)数据被采样。
（3）SPI通信根据时钟相位和时钟极性的不同组合，可以分为4种模式。
在嵌入式设备开发的过程中，第一件事就是确定其设备支持哪一种SPI通信模式。
常用的模式为：
CPOL=1，CPHA=1
即时钟空闲状态为高电平, 在时钟的上升沿采样数据。
SPI基本读写时序(CPOL=1，CPHA=1)
10.SPI拓扑图讲解
①MISO数据线接收到的信号经移位寄存器处理后把数据转移到接收缓冲区，然后这个数据就可以由
软件从接收缓冲区读出了。当要发送数据时，我们把数据写入发送缓冲区，硬件将会把它用移位寄
存器处理后输出到MOSI数据线。
②SCK的时钟信号则由波特率发生器产生，我们可以通过波特率控制位（BR）来控制它输出的波特
率。控制寄存器CR1掌控着主控制电路，STM32的SPI模块的协议设置（时钟极性，相位等）就由
它来制定。而控制寄存器CR2则用于设置各种中断使能。其中数据帧长度可以通过“控制寄存器
CR1”的“DFF位”配置成8位及16位模式;配置“LSBFIRST位”可选择MSB先行还是LSB先行。
③NSS引脚，这个引脚扮演着SPI协议中的SS片选信号线的角色，如果我们把NSS引脚配置为硬件自 动控制，SPI模块能够自动判别它能否成为SPI的主机，或自动进入SPI从机模式。但实际上我们用的 更多的是由软件控制某些GPIO引脚单独作为SS信号，这个GPIO引脚可以随便选择.

13.flash概述
Flash 接口可管理 CPU 通过 AHB I-Code 和 D-Code 对 Flash 进行的访问。该接口可针对 Flash 执行擦除和编程操作，并实施读写保护机制。Flash 接口通过指令预取和缓存机制加速 代码执行。
Flash 结构如下：
1● 主存储器块分为多个扇区。
2● 系统存储器，器件在系统存储器自举模式下从该存储器启动
3● 512 OTP（一次性可编程）字节，用于存储用户数据。
4● 选项字节，用于配置读写保护、BOR 级别、软件/硬件看门狗以及器件处于待机或停止模式下的 复位.
14.flash结构
Flash 结构如下：
— 主存储器块，分为 4 个 16 KB 扇区、1 个
64 KB 扇区和(最多) 7 个 128 KB 扇区
— 系统存储器，器件在系统存储器自举模式下
从该存储器启动
— 512 字节 OTP（一次性可编程），用于存储
用户数据
OTP 区域还有 16 个额外字节，用于锁定对应
的 OTP 数据块。
— 选项字节，用于配置读
15. 各种通信的区别
USART/I2C/SPI比较
1
、通信速率比较：
SPI > I2C >
UART
(1)
同步通信
>
异步通信
;
(2)
同步通信时必须有一根时钟线连接传输的两端
;
(3)
都是串行通信方式，并行通信用于内部存储间的通信，如
flash;
(4)
适合传输的距离和通信速率成反比关系；
2
、连线方式：
SPI
：
2
数据线、
1
时钟线、
1CS(
设备片选线），串行同步通信全双工；
I2C
：
1
数据线、
1
时钟线，串行同步通信半双工，传输距离比
UART
短；
UART
：
2
数据线、
1
地线，串行异步通信全双工，传输距离比
I2C
长些；
（
I2C
接口是
“
器件间
”
接口，是在一块板子之内传输数据）
（
UART
是
“
设备间
”
接口，更多的是用于两台设备之间传输数据）
