STM32F407实现1588v2(ptpd)

这篇具有很好参考价值的文章主要介绍了STM32F407实现1588v2(ptpd)。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

硬件：

STM32F407ZGT6开发板

软件：

VSCode

arm-none-eabi-gcc

openOCD

st-link

在github搜到一个在NUCLEO-F429ZI开发板上移植ptpd的example，因为和F407差别很小，所以就打算用这个demo移植到手头的开发板上。因为目前只需要slave，所以只调试了slave。据介绍，master好像原作者没有充分测试过。

1.修改ETH引脚

projects/nucleo_ptpd_slave/src/hal_system.c中 HAL_ETH_MspInit 函数里有ETH引脚初始化：

STM32F407实现1588v2(ptpd)

 根据自己手头板子调整引脚初始化，其实可以先用STM32CubeMX生成一个测试工程，测试一下板子硬件是好的再移植是最正确的流程。关于ETH硬件测试工程可以参考我之前的博文：

(GCC)从零开始的ETH开发--STM32F407ZGTX_我我我只会printf的博客-CSDN博客

这里记得在初始化完成后，使用复位引脚复位PHY。还有原工程是F429，现在改成F407需要修改头文件hal_system.h中：

STM32F407实现1588v2(ptpd)

还有时钟类型需要根据实际修改，一般都是外部晶振：

2.修改makefile

F429和F407启动文件不同，所以需要修改slave工程包含的makefile：

STM32F407实现1588v2(ptpd)

 其次删除newlib_stubs.c文件，否则编译后的固件没办法使用。

还有修改宏定义：

还有注意修改ld脚本文件，这里我使用的是自己新建的ld文件：

其他修改可有可无，根据自己情况修改。makefile文件如下：

注意我使用的gcc版本是：

如果你是用同样的版本，可以直接使用上述makefile，否则可能出现编译失败错误。

3.修改串口

串口配置在console.c文件中，因为我使用的串口和 USE_STM32F4_DISCOVERY 这个开发板串口相同，所以我在上文宏定义的地方直接使用了USE_STM32F4_DISCOVERY宏定义，如果你也按上文使用了USE_STM32F4_DISCOVERY宏定义，但是串口又不相同，请修改：

STM32F407实现1588v2(ptpd)

以及中断名称：

STM32F407实现1588v2(ptpd)

GCC下重定向printf请添加：

int _write (int fd, char *pBuffer, int size)
{
  for (int i = 0; i < size; i++)
  {
    if(pBuffer[i] == '\n')
      console_putc('\r');
    console_putc((int)pBuffer[i]);
  }
  return size;
}

4.修改报文

注意，此处修改只是我为了和电脑运行的ptp4l之间进行测试，如果不修改报文，ptp4l会认为报文异常。

STM32F407实现1588v2(ptpd)

还有slave和master之间稳定的限幅可以设置的大一点：

STM32F407实现1588v2(ptpd)

5.代码编译

至此所有修改完成，在slave工程目录下make即可：

STM32F407实现1588v2(ptpd)

STM32F407实现1588v2(ptpd)

6.代码运行

STM32F407实现1588v2(ptpd)

ubuntu下使用

sudo ptp4l -E -4 -S -i ens40 -m 

-i后跟网卡名称

    STM32F407普通IO口模拟串口实现不定长数据收发

    因为项目中用到的串口比较多，STM32F407VET6自带的串口不够用了，所以只能考虑用模拟串口来实现功能。普通的IO口来模拟串口需要先了解串口的时序图，需要用到两个IO引脚即收发引脚，两个定时器，一个用于发送延时使用，一个用于产生中断接收数据。代码的初始化主要用
