描述

注：* 为必填项

请在报名阶段填写 ↓

* 1、项目功能介绍

通过STM32微控制器与SG90舵机结合，打造一款迷你桌面宠物狗。该宠物狗具备坐下、行走、撒娇、摇摆等不同的动作姿态表演，增加互动乐趣。通过红外遥控器对宠物狗进行控制，用户可以方便地操控宠物狗进行动作表演。采用可充电锂电池供电，使用方便，具备一定的续航能力，确保长时间的使用。

这个简单有趣的入门小项目，不仅可以提高电子diy的乐趣，也可以作为入门教育项目，帮助小白了解单片机开发、舵机控制和红外传感技术等相关知识。

*2、项目属性

首次公开，原创

* 3、开源协议

GPL3.0

*4、硬件部分

4.1 系统框架

从图中可以看出该项目并不复杂，只需会使用红外通信技术，单片机定时器产生pwm波，舵机的驱动和oled图像显示，就可以制作这个简单的迷你桌面宠物狗。

4.2 主要构成

stm32单片机作为主控单元

sg90舵机作为运动控制单元

oled屏幕作为显示单元

通信方式采用红外通信

4.3 3D部件

用来给舵机装载oled屏幕

固定四个舵机

实物上身图：

4.4 原理图

只有五个舵机接口引出和一个红外接收头插口以及oled屏幕插口。

使用sg90舵机以及5v电源供电的话不需要加降压模块，用焊锡短路连接就行，添加一个可调降压模块是考虑到电源电压和舵机工作电压的多样性。

*5、软件部分

5.1 程序流程图

5.2 源码部分

5.2.1 主要文件

5.2.3 舵机驱动

定时器配置

PWM输出配置

基本配置完成后，可以通过这个公式，直接对舵机进行转动角度赋值

最后通过对四个舵机的协调就可以完成动作的实现的了：

5.2.2 红外通信

使用的正点原子红外遥控代码，定时读取Remote_Scan（）函数获得键值，再做出相应的动作处理

void TIM3_IRQHandler(void)

{

if(TIM_GetITStatus(TIM3,TIM_IT_Update)!=RESET)

{

if(RmtSta&0x80)//上次有数据被接收到了

{

RmtSta&=~0X10;//取消上升沿已经被捕获标记

if((RmtSta&0X0F)==0X00)RmtSta|=1<<6;//标记已经完成一次按键的键值信息采集

if((RmtSta&0X0F)<14)RmtSta++;

else

{

RmtSta&=~(1<<7);//清空引导标识

RmtSta&=0XF0;//清空计数器

}

if(TIM_GetITStatus(TIM3,TIM_IT_CC3)!=RESET)

{

if(RDATA)//上升沿捕获

{

TIM_OC3PolarityConfig(TIM3,TIM_ICPolarity_Falling); //CC4P=1 设置为下降沿捕获

TIM_SetCounter(TIM3,0);//清空定时器值

RmtSta|=0X10;//标记上升沿已经被捕获

}else //下降沿捕获

{

Dval=TIM_GetCapture3(TIM3);//读取CCR4也可以清CC4IF标志位

TIM_OC3PolarityConfig(TIM3,TIM_ICPolarity_Rising); //CC4P=0 设置为上升沿捕获

if(RmtSta&0X10)//完成一次高电平捕获

{

if(RmtSta&0X80)//接收到了引导码

{

if(Dval>300&&Dval<800)//560为标准值,560us

{

RmtRec<<=1;//左移一位.

RmtRec|=0;//接收到0

}else if(Dval>1400&&Dval<1800)//1680为标准值,1680us

{

RmtRec<<=1;//左移一位.

RmtRec|=1;//接收到1

}else if(Dval>2200&&Dval<2600)//得到按键键值增加的信息 2500为标准值2.5ms

{

RmtCnt++; //按键次数增加1次

RmtSta&=0XF0;//清空计时器

}

}else if(Dval>4200&&Dval<4700) //4500为标准值4.5ms

{

RmtSta|=1<<7;//标记成功接收到了引导码

RmtCnt=0;//清除按键次数计数器

}

RmtSta&=~(1<<4);

}

TIM_ClearITPendingBit(TIM3,TIM_IT_Update|TIM_IT_CC3);

}

//处理红外键盘

//返回值:

// 0,没有任何按键按下

//其他,按下的按键键值.

u8 sta;

u8 Remote_Scan(void)

{

u8 t1,t2;

if(RmtSta&(1<<6))//得到一个按键的所有信息了

{

t1=RmtRec>>24;//得到地址码

t2=(RmtRec>>16)&0xff;//得到地址反码

if((t1==(u8)~t2)&&t1==REMOTE_ID)//检验遥控识别码(ID)及地址

{

t1=RmtRec>>8;

t2=RmtRec;

if(t1==(u8)~t2)sta=t1;//键值正确

}

if((sta==0)||((RmtSta&0X80)==0))//按键数据错误/遥控已经没有按下了

{

RmtSta&=~(1<<6);//清除接收到有效按键标识

RmtCnt=0;//清除按键次数计数器

}

return sta;

}
