好的,我会为你提供代码,并附上中文注释。请注意,这里的代码仅供参考,具体实现可能需要根据实际情况进行调整。
```c
#include "main.h"
#include "stm32f0xx_hal.h"
#include <string.h>
UART_HandleTypeDef huart1;
void SystemClock_Config(void);

static void MX_USART1_UART_Init(void);
void esp8266_send_cmd(char *cmd);
void esp8266_receive_data(void);
int main(void)
{

MX_USART1_UART_Init();
char cmd[] = "AT\r\n"; // 测试AT指令是否可用
esp8266_send_cmd(cmd);
while (1)
{
esp8266_receive_data(); // 接收数据并输出到串口1
}
}
void esp8266_send_cmd(char *cmd)
{
HAL_UART_Transmit(&huart1, (uint8_t*)cmd, strlen(cmd), 1000); // 发送命令
}
void esp8266_receive_data(void)
{
char data;
if(HAL_UART_Receive(&huart1, (uint8_t*)&data, 1, 100) == HAL_OK) // 接收数据
{
HAL_UART_Transmit(&huart1, (uint8_t*)&data, 1, 1000); // 将接收到的数据输出到串口1
}
}

```
其中,`esp8266_send_cmd`函数用于发送指令,`esp8266_receive_data`函数用于接收数据并输出到串口1中。在主函数中,我们先发送一个测试AT指令的命令,然后不断接收数据并输出到串口1中。需要注意的是,这里仅实现了接收数据的功能,如果你需要发送数据到esp8266模块,还需要实现相应的函数。
希望这份代码对你有所帮助!
