在C语言中,为STC15W204S单片机的串口1设计一个接收字符串并通过串口中断的方式将它存入数组,需要按照以下步骤编写:
1. **包含头文件**:
```c
#include "stm8s.h" // 假设是STM8S系列单片机的头文件,包含串口库
```
2. **初始化串口**:
```c
void UART1_Init()
{
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9 | GPIO_Pin_10; // RX和TX引脚
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
USART_InitStructure.USART_BaudRate = YOUR_BAUD_RATE; // 设置波特率
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_Mode_Tx;
USART_Init(UART1, &USART_InitStructure);
USART_Cmd(UART1, ENABLE); // 启动串口
}
```
3. **设置串口中断**:
```c
void UART1_IRQHandler(void)
{
static char received_char = '\0';
if (USART_GetFlagStatus(UART1, USART_FLAG_RXNE) == SET)
{
received_char = USART_ReceiveData(UART1); // 接收字符
if (received_char == '\n' || received_char == '\r')
{
received_char = '\0'; // 收到换行符后认为字符串结束
// 将字符串存入数组
your_array[received_index++] = received_char; // 注意检查数组边界
if (received_index == ARRAY_SIZE(your_array))
break; // 字符串已满,中断接收
}
else
your_array[received_index++] = received_char; // 否则继续接收
}
}
void enable_UART1_interrupt() // 中断开中断
{
NVIC_EnableIRQ(UART1_IRQn);
}
```
4. **主函数中调用**:
```c
int main(void)
{
UART1_Init();
enable_UART1_interrupt();
while (1) { /* 等待接收字符串 */ }
return 0;
}
```
注意:你需要替换 `YOUR_BAUD_RATE` 和 `ARRAY_SIZE(your_array)` 为你实际使用的波特率以及数组的实际大小。
