STM32F10x-标准外设库 - STM32F10x-StdPeriph-Lib-V3.6.0
首先,你需要在stm32中使用UART和esp8266进行通信。你可以使用标准外设库中的UART函数来实现。然后,在stm32中将要发送的数组存储在一个缓冲区中,使用UART函数将其发送到esp8266。在esp8266中,你需要编写一个代码来接收通过UART发送的数据,并将其发送到Andriod Studio。
具体地,你可以使用AT指令来配置esp8266为TCP服务器,并将其连接到Andriod Studio使用的WiFi网络。然后,在Andriod Studio中,你可以编写一个TCP客户端代码来连接到esp8266,并接收其发送的数据。
在stm32中,你可以使用以下代码将数组发送到esp8266:
```c
#include "stm32f10x.h"
#include "stdio.h"
#include "string.h"
#define BUFFER_SIZE 50
uint8_t buffer[BUFFER_SIZE] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
void UART_send(uint8_t *data, uint16_t len)
{
for(int i = 0; i < len; i++)
{
USART_SendData(USART1, data[i]);
while (USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET);
}
}
int main(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_Init(USART1, &USART_InitStructure);
USART_Cmd(USART1, ENABLE);
while (1)
{
UART_send(buffer, BUFFER_SIZE);
delay_ms(1000);
}
}
```
在esp8266中,你可以使用以下代码将接收到的数据发送到Andriod Studio:
```c
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
WiFiServer server(80);
void setup()
{
Serial.begin(115200);
delay(10);
WiFi.begin("your_SSID", "your_PASSWORD");
while (WiFi.status() != WL_CONNECTED())
{
delay(500);
Serial.println("Connecting to WiFi...");
}
Serial.println("Connected to WiFi");
server.begin();
}
void loop()
{
WiFiClient client = server.available();
if (client)
{
while (client.connected())
{
while (client.available())
{
char c = client.read();
Serial.write(c);
}
}
client.stop();
}
}
```
在Andriod Studio中,你可以使用以下代码连接到esp8266并接收其发送的数据:
```java
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.Socket;
public class TcpClient {
public static void main(String[] args) {
try {
Socket socket = new Socket("esp8266_ip_address", 80);
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
}
socket.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
```
当然,这只是一个简单的示例,你可以根据你的具体需求进行修改和扩展。
