很抱歉,我无法提供完整的代码,但是我可以给你一些参考。
首先,你需要在stm32f103c8t6上运行一个程序来控制esp8266-01s模块。你可以使用STM32的UART串口和ESP8266-01s的AT指令来进行通信。
以下是一个简单的程序示例,可以让STM32通过ESP8266-01s连接到OneNet平台:
```c
#include "stm32f10x.h"
#include "stdio.h"
#include "string.h"
#define ESP8266_RX_BUFFER_SIZE 1024
#define ESP8266_TX_BUFFER_SIZE 1024
char esp8266_rx_buffer[ESP8266_RX_BUFFER_SIZE];
char esp8266_tx_buffer[ESP8266_TX_BUFFER_SIZE];
void esp8266_init(void)
{
USART_InitTypeDef USART_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOA, &GPIO_InitStructure);
USART_InitStructure.USART_BaudRate = 115200;
USART_InitStructure.USART_WordLength = USART_WordLength_8b;
USART_InitStructure.USART_StopBits = USART_StopBits_1;
USART_InitStructure.USART_Parity = USART_Parity_No;
USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
USART_InitStructure.USART_Mode = USART_Mode_Tx | USART_Mode_Rx;
USART_Init(USART1, &USART_InitStructure);
USART_Cmd(USART1, ENABLE);
}
void esp8266_send_command(char* command)
{
while (*command != '\0')
{
USART_SendData(USART1, *command++);
while (USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET);
}
}
void esp8266_receive_response(void)
{
int i = 0;
while (1)
{
while (USART_GetFlagStatus(USART1, USART_FLAG_RXNE) == RESET);
char c = USART_ReceiveData(USART1);
if (c == '\r' || c == '\n')
continue;
esp8266_rx_buffer[i++] = c;
if (i >= ESP8266_RX_BUFFER_SIZE)
break;
if (strstr(esp8266_rx_buffer, "OK") != NULL)
break;
if (strstr(esp8266_rx_buffer, "ERROR") != NULL)
break;
if (strstr(esp8266_rx_buffer, "FAIL") != NULL)
break;
}
}
void esp8266_connect_to_onenet(char* api_key, char* device_id)
{
sprintf(esp8266_tx_buffer, "AT+CWJAP=\"SSID\",\"PASSWORD\"\r\n");
esp8266_send_command(esp8266_tx_buffer);
esp8266_receive_response();
sprintf(esp8266_tx_buffer, "AT+CIPSTART=\"TCP\",\"api.heclouds.com\",80\r\n");
esp8266_send_command(esp8266_tx_buffer);
esp8266_receive_response();
sprintf(esp8266_tx_buffer, "AT+CIPSEND=%d\r\n", strlen(api_key) + strlen(device_id) + 70);
esp8266_send_command(esp8266_tx_buffer);
esp8266_receive_response();
sprintf(esp8266_tx_buffer, "POST /devices/%s/datapoints HTTP/1.1\r\n", device_id);
esp8266_send_command(esp8266_tx_buffer);
sprintf(esp8266_tx_buffer, "api-key:%s\r\n", api_key);
esp8266_send_command(esp8266_tx_buffer);
sprintf(esp8266_tx_buffer, "Host: api.heclouds.com\r\n");
esp8266_send_command(esp8266_tx_buffer);
sprintf(esp8266_tx_buffer, "Content-Type: application/json\r\n");
esp8266_send_command(esp8266_tx_buffer);
sprintf(esp8266_tx_buffer, "Content-Length: 25\r\n\r\n");
esp8266_send_command(esp8266_tx_buffer);
sprintf(esp8266_tx_buffer, "{\"datastreams\":[{\"id\":\"temp\",\"datapoints\":[{\"value\":\"26.5\"}]}]}\r\n");
esp8266_send_command(esp8266_tx_buffer);
esp8266_receive_response();
sprintf(esp8266_tx_buffer, "AT+CIPCLOSE\r\n");
esp8266_send_command(esp8266_tx_buffer);
esp8266_receive_response();
}
int main(void)
{
char* api_key = "your_api_key_here";
char* device_id = "your_device_id_here";
esp8266_init();
esp8266_connect_to_onenet(api_key, device_id);
while (1)
{
}
}
```
在这个示例中,我们使用了ESP8266-01s模块连接到OneNet平台,并发送了一个简单的JSON数据点。这个程序只是一个示例,你需要根据自己的需求进行修改和扩展。同时,请确保你已经正确连接了ESP8266-01s模块到你的STM32开发板上。
