dm9162 stm32驱动配置程序

DM9162是一款高性能以太网PHY芯片，常用于STM32的网络应用中。下面是一个基本的STM32驱动配置程序示例：

#include "stm32f10x.h"
#include "dm9162.h"

void ETH_GPIO_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB | RCC_APB2Periph_GPIOC, ENABLE);

    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1 | GPIO_Pin_5 | GPIO_Pin_11;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOB, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1 | GPIO_Pin_4 | GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOC, &GPIO_InitStructure);
}

void ETH_DM9162_Configuration(void)
{
    ETH_InitTypeDef ETH_InitStructure;

    RCC_AHBPeriphClockCmd(RCC_AHBPeriph_ETH_MAC | RCC_AHBPeriph_ETH_MAC_Tx | RCC_AHBPeriph_ETH_MAC_Rx, ENABLE);

    ETH_InitStructure.ETH_RetryTransmission = ETH_RetryTransmission_Enable;
    ETH_InitStructure.ETH_AutomaticPadCRCStrip = ETH_AutomaticPadCRCStrip_Enable;
    ETH_InitStructure.ETH_BackOffLimit = ETH_BackOffLimit_10;
    ETH_InitStructure.ETH_DeferralCheck = ETH_DeferralCheck_Enable;

    ETH_InitStructure.ETH_SourceAddrFilter = ETH_SourceAddrFilter_Enable;
    ETH_InitStructure.ETH_PassControlFrames = ETH_PassControlFrames_BlockAll;

    ETH_InitStructure.ETH_PromiscuousMode = ETH_PromiscuousMode_Disable;
    ETH_InitStructure.ETH_MulticastFramesFilter = ETH_MulticastFramesFilter_Perfect;
    ETH_InitStructure.ETH_UnicastFramesFilter = ETH_UnicastFramesFilter_Perfect;
    ETH_InitStructure.ETH_HashTableHigh = 0x0;

    ETH_Init(&ETH_InitStructure, DM9162_PHYAddress);

    ETH_DM9162_Init(DM9162_PHYAddress);
}

int main(void)
{
    ETH_GPIO_Configuration();
    ETH_DM9162_Configuration();

    while (1)
    {
        // Your code here
    }
}

在这个示例程序中，我们定义了两个函数 `ETH_GPIO_Configuration` 和 `ETH_DM9162_Configuration`。`ETH_GPIO_Configuration` 函数配置了STM32的GPIO引脚，使其能够连接到DM9162芯片上。`ETH_DM9162_Configuration` 函数初始化了以太网控制器，并配置了DM9162 PHY芯片。

最后，在 `main` 函数中，我们调用了这两个函数，并在主循环中添加了自己的代码。
