概述
本文主要介绍基于STM32芯片实现DRV8353RS的驱动程序，文中介绍DRV8353RS的SPI接口的时序，还介绍了主要的驱动程序接口，并验证了该程序的功能。
1. 硬件接口定义
1.1 DRV8353RS的SPI控制模块
1） DRV8353RS与MCU之间的通信接口
2）使能DRV8353RS控制接口
1.2 时序介绍
在DRV835x SPI设备上，SPI总线用于设置设备配置、运行参数和读取诊断信息。SPI在从属模式下工作并连接到主控制器。SPI输入数据（SDI）字由一个16位字、一个5位命令和11位数据组成。SPI输出数据（SDO）字由11位寄存器数据组成。前5位是无所谓位。
一个有效的帧必须满足以下条件：
•当nSCS引脚：从高到低和从低到高转换时，SCLK引脚应该是低的。
•nSCS引脚： 应在单词之间至少拉高400ns。
•当nSCS引脚： 被拉高时，在SCLK和SDI引脚的任何信号都被忽略，SDO引脚被设置
Hi-Z。数据在SCLK的下降沿上捕获，数据在SCLK的上升沿上传播。最高有效位（MSB）首先被移进移出。
•事务必须经过16个SCLK周期才有效。
•如果发送到SDI引脚的数据字不是16位，则会发生帧错误并忽略该数据字。
•对于写命令，要写入的寄存器中的现有数据在SDO引脚上跟随5位命令数据移出。
•SDO引脚是一个开漏输出，需要一个外部上拉电阻。
1.3 数据格式
SDI输入数据字长16位，由以下格式组成：
•1个读写位， W （B15位）
•4个地址位， A （B14到B11位）
•11位数据位 D （ B11到B0位）
设置写命令的读写位（W0, B15）为0b。设置读命令的读写位（W0, B15）为1b。
设置W0( B15 ) = 0: 写参数模式使能
设置W0( B15 ) = 1: 读参数模式使能
SDO输出数据字长16位，前5位是无关位。响应字是当前正在访问的寄存器中的数据。

4）Register Map
2 驱动代码实现
2.1 STM32Cube配置接口

2.2 驱动程序实现
2.2.1 接口函数实现
1） 定义输入参数数据结构
2） 写参数函数
3）读参数函数
2.2.2 default参数配置

3.1 参数初始化
3.2 测试函数实现
