    匿名四轴上位机使用手册

    1、串口功能

    软件界面

    串口功能和串口助手等软件功能类似,设置也差不多。

    1.设置接收格式、端口、波特率即可。

    2.打开基本收码功能。

    3.打开串口。 

    4.测试:

     2、高级收码

    高级收码设置选项卡:

     

    1.1-10对应0XA1-0XAA,我们只需要按定义帧设置即可,我这里使用0XA2,选择2,并打开开关。

    2.因为我需要查看的有三个数据,pitch,roll,yaw,并为float类型,所以如此设置。

    3.最后打开高级收码功能,如果你需要实时查看上传的数据可以打开收码显示。

    4.打开串口。 

    5.测试:

     

     3、波形显示

    波形显示功能需要在高级收码的功能上做修改。

    波形显示设置选项卡如下:

     

    1.1-20序号对应的是波形序号,也就是说最多能指定显示20个波形,我们这里有pitch,roll,yaw三个波形,所以设置1,2,3。

    2.设置第一个波形1,它来源于数据帧2的第一位。

    3.设置第一个波形2,它来源于数据帧2的第二位。

    4.设置第一个波形3,它来源于数据帧2的第三位。

    5.打开数据校验,数据显示。

    6.打开波形显示。

    7.在波形显示页面勾上前三个即可:

    8.打开串口。

    9.测试:

     

    4、飞控状态

    使用到此功能再补充。

    5、上传数据的单片机程序

    以下为上传三个角度的代码,串口初始化等略过:

    void usart1_send_char(u8 c)
    {
        while((USART1->SR&0X40)==0);//等待上一次发送完毕  
        USART1->DR=c;   
    }
     
    //fun:功能字. 0XA0~0XAF
    //data:数据缓存区,最多28字节!!
    //len:data区有效数据个数
    void usart1_niming_report(u8 fun,u8*data,u8 len)
    {
        u8 send_buf[32];
        u8 i;
        if(len>28)return;    //最多28字节数据
        send_buf[len+3]=0;  //校验数置零
        send_buf[0]=0X88;   //帧头
        send_buf[1]=fun;    //功能字
        send_buf[2]=len;    //数据长度
        for(i=0;i<len;i++)send_buf[3+i]=data[i];         //复制数据
        for(i=0;i<len+3;i++)send_buf[len+3]+=send_buf[i];    //计算校验和
        for(i=0;i<len+4;i++)usart1_send_char(send_buf[i]);   //发送数据到串口1
    }
     
    void mpu6050_send_data(float pitch,float roll,float yaw)
    {
        u8 tbuf[16];
        unsigned char *p;
        p=(unsigned char *)&pitch;
        tbuf[0]=(unsigned char)(*(p+3));
        tbuf[1]=(unsigned char)(*(p+2));
        tbuf[2]=(unsigned char)(*(p+1));
        tbuf[3]=(unsigned char)(*(p+0));
         
        p=(unsigned char *)&roll;
        tbuf[4]=(unsigned char)(*(p+3));
        tbuf[5]=(unsigned char)(*(p+2));
        tbuf[6]=(unsigned char)(*(p+1));
        tbuf[7]=(unsigned char)(*(p+0));
         
        p=(unsigned char *)&yaw;
        tbuf[8]=(unsigned char)(*(p+3));
        tbuf[9]=(unsigned char)(*(p+2));
        tbuf[10]=(unsigned char)(*(p+1));
        tbuf[11]=(unsigned char)(*(p+0));
         
        usart1_niming_report(0XA2,tbuf,12);//自定义帧,0XA2
    }  

    注意:最后一个函数把float拆成四个字节发送(由于串口只能一个字节一个字节的发送),用指针获得float型变量的首地址,然后强制转换为unsigned char型,地址逐渐加大把float的四个字节分别发出即可。
