w5500 stm32开发hal库

我可以回答这个问题。w5500是一款基于TCP/IP协议的以太网控制器，而STM32是一款微控制器，HAL库是STM32的一个软件库，用于简化开发者的编程工作。因此，w5500 stm32开发hal库是指在STM32上使用HAL库来开发w5500以太网控制器。

stm32f103 hal库驱动W5500代码

以下是使用STM32CubeMX和HAL库驱动W5500的代码示例，使用SPI通信：

#include "main.h"
#include "spi.h"
#include "gpio.h"

#include "w5500.h"
#include "socket.h"

#define WIZ_RESET_PORT  GPIOA
#define WIZ_RESET_PIN   GPIO_PIN_1

void WIZ_CS_Select(void)
{
  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_RESET);
}

void WIZ_CS_Deselect(void)
{
  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_SET);
}

void WIZ_SPI_Transmit(uint8_t *buf, uint16_t len)
{
  HAL_SPI_Transmit(&hspi1, buf, len, 1000);
}

void WIZ_SPI_Receive(uint8_t *buf, uint16_t len)
{
  HAL_SPI_Receive(&hspi1, buf, len, 1000);
}

void WIZ_Delay_ms(uint32_t ms)
{
  HAL_Delay(ms);
}

int main(void)
{
  HAL_Init();

  MX_GPIO_Init();
  MX_SPI1_Init();

  WIZ_RESET_PORT->BSRR = WIZ_RESET_PIN; // Deassert reset
  HAL_Delay(10);
  WIZ_RESET_PORT->BRR = WIZ_RESET_PIN; // Assert reset
  HAL_Delay(10);
  WIZ_RESET_PORT->BSRR = WIZ_RESET_PIN; // Deassert reset
  HAL_Delay(1000); // Wait for W5500 to initialize

  uint8_t mac_addr[6] = {0x00, 0x08, 0xDC, 0x11, 0x22, 0x33};
  uint8_t ip_addr[4] = {192, 168, 0, 10};
  uint8_t gateway_addr[4] = {192, 168, 0, 1};
  uint8_t subnet_mask[4] = {255, 255, 255, 0};

  WIZ_Init(mac_addr, ip_addr, gateway_addr, subnet_mask);

  while (1)
  {
    uint8_t socket_num = 0;
    uint16_t port = 80;
    uint8_t server_ip_addr[4] = {192, 168, 0, 2};
    uint16_t server_port = 8080;

    // Open socket
    uint8_t socket_status = 0;
    socket_num = socket(0, Sn_MR_TCP, port, 0);
    if (socket_num != 0xFF)
    {
      socket_status = getSn_SR(socket_num);
      if (socket_status == SOCK_INIT)
      {
        // Connect to server
        connect(socket_num, server_ip_addr, server_port);
        socket_status = getSn_SR(socket_num);
        if (socket_status == SOCK_ESTABLISHED)
        {
          // Send data to server
          uint8_t tx_buf[] = "Hello, server!";
          send(socket_num, tx_buf, sizeof(tx_buf));
          socket_status = getSn_SR(socket_num);
          if (socket_status == SOCK_ESTABLISHED)
          {
            // Receive data from server
            uint8_t rx_buf[1024] = {0};
            uint16_t rx_len = recv(socket_num, rx_buf, sizeof(rx_buf));
            if (rx_len > 0)
            {
              // Process received data
            }
          }
        }
        // Close socket
        close(socket_num);
      }
    }
    HAL_Delay(1000);
  }
}

在此示例中，`WIZ_Init`函数用于初始化W5500，`socket`、`connect`、`send`和`recv`函数用于与服务器进行TCP通信。注意，在使用W5500之前需要正确配置引脚、SPI和时钟。

stm32f103 hal库驱动W5500详细代码

以下是基于STM32CubeIDE和HAL库的W5500驱动代码：

首先，在CubeMX中配置GPIO和SPI，然后生成代码。

然后，在main.c文件中初始化W5500并设置其寄存器。

#include "main.h"
#include "spi.h"
#include "gpio.h"
#include "w5500.h"

W5500_Dev w5500_dev;

int main(void)
{
  HAL_Init();
  MX_GPIO_Init();
  MX_SPI1_Init();

  W5500_Init(&w5500_dev, &hspi1, GPIOA, GPIO_PIN_4);

  W5500_SetMACAddress(&w5500_dev, (uint8_t *)"AA:BB:CC:DD:EE:FF");
  W5500_SetIPAddress(&w5500_dev, 192, 168, 1, 100);
  W5500_SetGatewayAddress(&w5500_dev, 192, 168, 1, 1);
  W5500_SetSubnetMask(&w5500_dev, 255, 255, 255, 0);

  while (1)
  {
    // loop
  }
}

在w5500.h头文件中定义了驱动的API函数。

#ifndef __W5500_H
#define __W5500_H

#ifdef __cplusplus
extern "C" {
#endif

#include "stm32f1xx_hal.h"

#define W5500_REGISTER_BLOCK_SIZE 0x400
#define W5500_REGISTER_BLOCK_SIZE_SHIFT 10

typedef struct
{
    SPI_HandleTypeDef *spi;
    GPIO_TypeDef *cs_port;
    uint16_t cs_pin;
} W5500_Dev;

void W5500_Init(W5500_Dev *dev, SPI_HandleTypeDef *spi, GPIO_TypeDef *cs_port, uint16_t cs_pin);
void W5500_SetMACAddress(W5500_Dev *dev, uint8_t *mac);
void W5500_SetIPAddress(W5500_Dev *dev, uint8_t ip1, uint8_t ip2, uint8_t ip3, uint8_t ip4);
void W5500_SetGatewayAddress(W5500_Dev *dev, uint8_t ip1, uint8_t ip2, uint8_t ip3, uint8_t ip4);
void W5500_SetSubnetMask(W5500_Dev *dev, uint8_t ip1, uint8_t ip2, uint8_t ip3, uint8_t ip4);

#ifdef __cplusplus

#endif /* __W5500_H */

在w5500.c文件中实现了这些API函数。

#include "w5500.h"

void W5500_Init(W5500_Dev *dev, SPI_HandleTypeDef *spi, GPIO_TypeDef *cs_port, uint16_t cs_pin)
{
    dev->spi = spi;
    dev->cs_port = cs_port;
    dev->cs_pin = cs_pin;

    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_SET);

    uint8_t tx_data[3] = {0x00, 0x00, W5500_MODE_VALUE};
    uint8_t rx_data[3] = {0};
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_RESET);
    HAL_SPI_TransmitReceive(dev->spi, tx_data, rx_data, sizeof(tx_data), W5500_SPI_TIMEOUT);
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_SET);
}

void W5500_SetMACAddress(W5500_Dev *dev, uint8_t *mac)
{
    uint8_t tx_data[7] = {0x00, 0x09, mac[0], mac[1], mac[2], mac[3], mac[4]};
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_RESET);
    HAL_SPI_Transmit(dev->spi, tx_data, sizeof(tx_data), W5500_SPI_TIMEOUT);
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_SET);
}

void W5500_SetIPAddress(W5500_Dev *dev, uint8_t ip1, uint8_t ip2, uint8_t ip3, uint8_t ip4)
{
    uint8_t tx_data[5] = {0x00, 0x0F, ip1, ip2, ip3, ip4};
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_RESET);
    HAL_SPI_Transmit(dev->spi, tx_data, sizeof(tx_data), W5500_SPI_TIMEOUT);
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_SET);
}

void W5500_SetGatewayAddress(W5500_Dev *dev, uint8_t ip1, uint8_t ip2, uint8_t ip3, uint8_t ip4)
{
    uint8_t tx_data[5] = {0x00, 0x01, ip1, ip2, ip3, ip4};
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_RESET);
    HAL_SPI_Transmit(dev->spi, tx_data, sizeof(tx_data), W5500_SPI_TIMEOUT);
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_SET);
}

void W5500_SetSubnetMask(W5500_Dev *dev, uint8_t ip1, uint8_t ip2, uint8_t ip3, uint8_t ip4)
{
    uint8_t tx_data[5] = {0x00, 0x05, ip1, ip2, ip3, ip4};
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_RESET);
    HAL_SPI_Transmit(dev->spi, tx_data, sizeof(tx_data), W5500_SPI_TIMEOUT);
    HAL_GPIO_WritePin(dev->cs_port, dev->cs_pin, GPIO_PIN_SET);
}

这些函数中，主要的操作是通过SPI总线向W5500写入寄存器的值。每个寄存器都有一个地址，可以在W5500的数据手册中找到。

注意，这里只给出了一些基本的初始化函数，还可以写更多的函数来配置其他寄存器。同时，还需要编写其他函数来读取和写入数据包以进行网络通信。
