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。
