下面是一个简单的STM32串口接收程序示例:
```c
#include "stm32f10x.h"
void USART1_IRQHandler(void)
{
if(USART_GetITStatus(USART1, USART_IT_RXNE) != RESET)
{
uint8_t data = USART_ReceiveData(USART1);
// 处理接收到的数据
}
}
int main(void)
{
// 初始化串口
USART_InitTypeDef USART_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_Rx;
USART_Init(USART1, &USART_InitStructure);
USART_Cmd(USART1, ENABLE);
// 使能串口接收中断
USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);
NVIC_EnableIRQ(USART1_IRQn);
while(1)
{
// 主循环中可以执行其他任务
}
}
```
