STM32F103C8T6连接ESP8266软件设计

连接STM32F103C8T6和ESP8266需要使用串口通信。你可以使用STM32F103C8T6的USART模块和ESP8266的串口模块进行通信。

以下是一个简单的程序示例，可用于在STM32F103C8T6和ESP8266之间进行串口通信：

#include "stm32f10x.h"
#include <string.h>

#define USART_BAUDRATE 9600
#define AP_SSID "Your_AP_SSID"
#define AP_PASSWORD "Your_AP_PASSWORD"
#define SERVER_IP "Server_IP_Address"
#define SERVER_PORT 80

void USART_Init(void);
void USART_SendString(char* str);
void delay_ms(uint32_t nTime);

int main(void)
{
    USART_Init();

    // 连接WiFi网络
    USART_SendString("AT+CWJAP=\"" AP_SSID "\",\"" AP_PASSWORD "\"\r\n");
    delay_ms(1000);

    // 建立TCP连接
    USART_SendString("AT+CIPSTART=\"TCP\",\"" SERVER_IP "\",\"" SERVER_PORT "\"\r\n");
    delay_ms(1000);

    // 发送数据
    USART_SendString("AT+CIPSEND=4\r\n");
    delay_ms(1000);
    USART_SendString("test");

    while(1);
}

void USART_Init()
{
    GPIO_InitTypeDef GPIO_InitStruct;
    USART_InitTypeDef USART_InitStruct;
    NVIC_InitTypeDef NVIC_InitStruct;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, ENABLE);

    GPIO_InitStruct.GPIO_Pin = GPIO_Pin_9;
    GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStruct);

    GPIO_InitStruct.GPIO_Pin = GPIO_Pin_10;
    GPIO_InitStruct.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStruct);

    USART_InitStruct.USART_BaudRate = USART_BAUDRATE;
    USART_InitStruct.USART_WordLength = USART_WordLength_8b;
    USART_InitStruct.USART_StopBits = USART_StopBits_1;
    USART_InitStruct.USART_Parity = USART_Parity_No;
    USART_InitStruct.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
    USART_InitStruct.USART_Mode = USART_Mode_Tx | USART_Mode_Rx;
    USART_Init(USART1, &USART_InitStruct);

    NVIC_InitStruct.NVIC_IRQChannel = USART1_IRQn;
    NVIC_InitStruct.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStruct.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStruct.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStruct);

    USART_Cmd(USART1, ENABLE);
}

void USART_SendString(char* str)
{
    uint16_t len = strlen(str);

    for(int i=0; i<len; i++)
    {
        USART_SendData(USART1, str[i]);
        while(USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET);
    }
}

void delay_ms(uint32_t nTime)
{
    uint32_t TimingDelay = nTime * 1000;

    while(TimingDelay != 0)
    {
        TimingDelay--;
    }
}

请注意，此示例仅用于演示如何在STM32F103C8T6和ESP8266之间进行串口通信。您需要根据您的实际情况修改代码，包括WiFi网络名称、密码、服务器IP地址和端口号等。
