stm32f103zet6怎么同时设置两个串口,一个用于接收蓝牙的数据,一个用于接收openmv的数据

在STM32F103ZET6上，可以同时设置两个串口来接收蓝牙和OpenMV的数据。具体步骤如下：

1. 配置UART1和UART2的时钟使能。

2. 配置UART1和UART2的GPIO引脚，设置为复用推挽输出模式。

3. 配置UART1和UART2的波特率、停止位、数据位等通信参数。

4. 配置UART1和UART2的中断，使它们能够接收数据并进行处理。

5. 在中断处理函数中，分别处理UART1和UART2接收到的数据，并进行相应的操作。

下面是一个简单的示例代码：

#include "stm32f10x.h"

void UART1_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    USART_InitTypeDef USART_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    // 使能UART1和GPIOA的时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE);

    // 配置UART1的GPIO引脚
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9; // TX
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10; // RX
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 配置UART1的通信参数
    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_Mode_Tx;
    USART_Init(USART1, &USART_InitStructure);

    // 配置UART1的中断
    NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);

    // 使能UART1
    USART_Cmd(USART1, ENABLE);
}

void UART2_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    USART_InitTypeDef USART_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    // 使能UART2和GPIOA的时钟
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_USART2, ENABLE);

    // 配置UART2的GPIO引脚
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2; // TX
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;

    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_3; // RX
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 配置UART2的通信参数
    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_Mode_Tx;
    USART_Init(USART2, &USART_InitStructure);

    // 配置UART2的中断
    NVIC_InitStructure.NVIC_IRQChannel = USART2_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    USART_ITConfig(USART2, USART_IT_RXNE, ENABLE);

    // 使能UART2
    USART_Cmd(USART2, ENABLE);
}

void USART1_IRQHandler(void)
{
    if (USART_GetITStatus(USART1, USART_IT_RXNE) != RESET)
    {
        // 处理UART1接收到的数据
        uint8_t data = USART_ReceiveData(USART1);
        // ...
    }
}

void USART2_IRQHandler(void)
{
    if (USART_GetITStatus(USART2, USART_IT_RXNE) != RESET)
    {
        // 处理UART2接收到的数据
        uint8_t data = USART_ReceiveData(USART2);
        // ...
    }
}

int main(void)
{
    // 初始化UART1和UART2
    UART1_Init();
    UART2_Init();

    while (1)
    {
        // 主循环
