gd32f450以太网配置

GD32F450系列控制器集成了一个以太网外设，支持10Mbps或100Mbps的数据传输速率，并通过DMA控制器进行介质访问控制(MAC)。该以太网外设可以按照IEEE 802.3-2002和IEEE 1588-2008标准发送和接收MAC数据包。要配置GD32F450的以太网，可以通过配置BCR寄存器和BSR寄存器实现。具体地说，通过调用ST官方的以太网库的HAL_ETH_ReadPHYRegister()和HAL_ETH_WritePHYRegister()函数来完成对PHY芯片寄存器的读写操作。在LAN8720初始化过程中，调用HAL_ETH_Init()函数后，会根据输入的参数配置LAN8720的相应寄存器，从而完成GD32F450的以太网配置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
