STM32f407探索者 ThreadX NetXDuo
2023-12-16 17:59:57
本文带来的是正点原子的开发板STM32F407探索者使用ThreadX和NetX的教程，工程文件是通过CubeMX创建的，导出为MDK在进行编辑。
一.创建工程
打开CubeMX选择stm32f407zgt6 144引脚版本，由于板子带的是lan8720的网口，我试过用lan8742的PHY也可以正常驱动，这点还是很方便的。
打开SoftWare Packs
然后我们设置时钟
然后开启ETH，一定要选中断！！！正点原子的板子引脚和CubeMX默认的不同，所以要修改一下
一定要选中断！！！一定要选中断！！！一定要选中断！！！一定要选中断！！！一定要选中断！！！
我开了一个串口，方便自己看调试信息什么的
然后设置GPIO，PD3是ETH的复位引脚，这个和别的板子也不同，如果这里不设置，则上电后无法初始化ETH，网口的灯是不会亮起的。
点击Project Manager，修改工程的Firmware Package。
生成工程，然后打开。
二.设置NetX静态IP实现ping
在工程栏里，这三个文件和NetX是最相关的，8720和8742都可以用同一套，但是如果换了别的网口，则需要修改里面的文件。一个是对应网口的驱动，比如上面的lan8742.c，一个是PHY层的NetX驱动，对应的是nx_stm32_phy_driver.c。正常情况下默认的nx_stm32_eth_driver.c不用修改。适配不同的网卡只需要改lan8742.c和nx_stm32_phy_driver.c
打开main.c 因为正点原子的板子需要给PD3引脚复位才可以正常启动MX_ETH_INIT，在上面添加对应代码。
打开app_netxduo.c和app_netxduo.h

编译工程，然后下装。我用的是DAP
三.测试?
下装以后可以看到ETH网口的灯亮起来了，这说明物理层已经正常启动了。?
修改电脑的IP地址，工程用的是192.168.4.36这个IP。电脑要在同一个域里，改成192.168.4.100?
可以看到正常ping通了。
我后面看了一下论坛老哥里的8720的驱动包，其实代码内容和8742是一样的。。。也贴上来好了。
