以下是基于STM32F103C8T6和HC-05蓝牙模块的通信代码示例:
首先需要初始化串口和蓝牙模块:
```c
#include "stm32f10x.h"
#include "stdio.h"
UART_HandleTypeDef huart1;
void UART1_Init(void)
{
huart1.Instance = USART1;
huart1.Init.BaudRate = 9600;
huart1.Init.WordLength = UART_WORDLENGTH_8B;
huart1.Init.StopBits = UART_STOPBITS_1;
huart1.Init.Parity = UART_PARITY_NONE;
huart1.Init.Mode = UART_MODE_TX_RX;
huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE;
HAL_UART_Init(&huart1);
}
void HC05_Init(void)
{
char buf[32];
HAL_Delay(1000);
sprintf(buf, "AT\r\n");
HAL_UART_Transmit(&huart1, (uint8_t *)buf, strlen(buf), 0xFFFF);
HAL_Delay(1000);
sprintf(buf, "AT+NAME=HC05\r\n");
HAL_UART_Transmit(&huart1, (uint8_t *)buf, strlen(buf), 0xFFFF);
HAL_Delay(1000);
sprintf(buf, "AT+ROLE=0\r\n");
HAL_UART_Transmit(&huart1, (uint8_t *)buf, strlen(buf), 0xFFFF);
HAL_Delay(1000);
}
```
然后可以实现数据发送和接收:
```c
void Send_Data(uint8_t *data, uint16_t len)
{
HAL_UART_Transmit(&huart1, data, len, 0xFFFF);
}
void Receive_Data(uint8_t *data)
{
HAL_UART_Receive(&huart1, data, 1, 0xFFFF);
}
```
最后在main函数中调用初始化函数和数据收发函数:
```c
int main(void)
{
HAL_Init();
UART1_Init();
HC05_Init();
uint8_t data[50];
while (1)
{
Receive_Data(data);
Send_Data(data, strlen((char *)data));
}
}
```
需要注意的是,HC-05模块的波特率要与初始化函数中的波特率保持一致,上述代码中波特率为9600。此外,在实际使用中需要根据需要修改蓝牙模块的名称、角色等参数。
