前言

如今智能信息时代发展迅猛，年轻一代享受着时代红利，而上了年纪的长辈却越来越迷茫，对于智能手机根本搞不清使用方法，很多老人只能退而求其次，使用老人机满足打电话这样的就基本需求，同时老人机存在很多局限：有时老人家会因为心痛电话费刻意控制时长；大多数老人机只能打电话，不能视频通话。如今网络如此发达，微信作为全球统一的及时通讯软件，不但通话免费，还能打视频电话，为何不开发针对老人的微信版本呢？只知道儿童智能手表可以打微信电话，但还是无法满足所有痛点，开造：

项目说明

思路：基于STM32的USB鼠标控制手机完成自动化控制操作，一般的手机都支持USB OTG功能。但OTG功能存在一个很大的弊端，就是无法边充电边使用，本文设计功能切换电路解决了这一问题，可闲时给手机充电。制作此项目需要参考我的前两篇博文。

所需材料

旧安卓智能手机
5pin的MicroUSB接头
矩阵键盘
STM32F103C8T6最小系统板
手机支架
mos管或继电器

二、硬件设计

1 接线示意图

1.1 矩阵键盘

矩阵键盘内部接线示意图如下：

1.2 MicroUSB OTG接口功能切换电路

MicroUSB有5个引脚，其中两个用来供电（VCC、GND），两个用来传输数据（D+、D-）,还有一个ID引脚是用来选择OTG功能的。当ID接地时，手机会启用OTG功能，当ID悬空时为普通数据线功能。经过反复实验，发现手机在MicroUSB刚插入时才检测是否开启OTG功能，为了**模拟插入和拔出的操作，用MOS管来断电，用单片机控制ID引脚的电平，实现功能切换，达到空闲时充电的目的。**手头只要一颗IRF540N的N型MOS管，只能用如下电路控制。

根据数据手册，此MOS管过于大材小用，VDSS = 100V RDS(on) = 44mΩ ID = 33A。
同时VGSth在2-4V之间，而单片机IO在输出电压为3.3V,虽然在这个范围内，但为了使MOS能够完全导通，利用开漏输出功能配合上拉电阻可将IO口输出电压提高到5V。

2 焊接

为了省去焊接的麻烦，画了一个PCB板，第一板存在一些小问题（没有画入MOS管，加入了音频功放功能作为拓展可以忽略），以上述接线图为准。

1 引脚配置

根据以上配置好USB鼠标后配置键盘引脚和USB OTG功能切换控制引脚。
将键盘的8个引脚全部配置为上拉模式，其中4个为输出口、4个为输入口

将USB OTG控制的两个引脚配置为开漏输出，可修改名称方便阅读

2.1 修改usb_device.c文件

在编写鼠标控制程序时发现鼠标只能相对移动，无法移动绝对位置，而点击屏幕最重要的时移动到屏幕指定位置。为了解决这一问题，本文采用的方案为：

相对移动

计算绝对位置

添加静态变量

/* USER CODE BEGIN 0 */
static int16_t Px=0,Py=0;//绝对位置
static uint8_t L=0,R=0,M=0;//鼠标上三个按键状态
/* USER CODE END 0 */

添加鼠标基本控制函数

	HAL_Delay(100);
}
//滚轮滚动
void Scroll(int8_t z)
{
	Set_Mouse(0,0,z,L,R,M);
}
//鼠标相对移动

	Set_Mouse(x,y,0,L,R,M);
}
//鼠标移动到最左上角
void Move_Reset(void)
{
	uint8_t i=16;
	while(i--)Move(-120,-120);
  Px = Py = 0;
}
//鼠标绝对移动
void Move_To(int16_t x,int16_t y)

}
//单击左键

回到微信主页

点击通讯录

点击字母A

点击A分组下的联系人

void Choose_Name(int8_t num)
{
	//点击5次返回图标，确保当前页面为微信主页，为了防止程序在微信中点错
	Move_To_Click(40,100);
	Move_To_Click(40,100);
	Move_To_Click(40,100);
	Move_To_Click(40,100);
	Move_To_Click(40,100);
	Move_To_Click(400,1740);//点击通讯录
	HAL_Delay(1000);//等待1s
	Move_To_Click(1050,410);//点击A
	HAL_Delay(1000);//等待1s
	Move_To_Click(200,num*133+350);//点击联系人名字 A0是350 A9是1550 均分1200/9=133
}

开始呼叫
这一步较简单。

添加USB OTG功能切换函数

}

/* USER CODE END 4 */

声明USB OTG状态标志位变量

/* USER CODE BEGIN PV */
static uint8_t USB_OTG_FLAG=0; 
/* USER CODE END PV */

声明以上三个函数

/* USER CODE BEGIN PFP */
static void USB_OTG_ON(void);
static void USB_OTG_OFF(void);
uint8_t Key_Scan(void);
/* USER CODE END PFP */

编写主函数程序
