a3a5dc2af9 开发进行中：添加输入捕获实验支持 
在ultrasonic_driver项目中，此次提交标志着向主目录添加新的源文件和头文件，旨在支持输入捕获实验。修改了CMakeLists.txt以包含新的input_capture_exp.c文件，同时在src和inc目录下分别创建了相应的源码和头文件。此外，此次提交还引入了输入捕获相关的硬件配置和初始化例程，为后续的功能开发和测试奠定了基础。

# XLSW-3DP-Ultrasonic-300K
## 传感器数据传输与样式
- USART
- baudrate 115200
- 8N1
- 数据格式
```cap_val:183 Distance: 7361 Temp:2735```
- cap_val:183 超声死区外的ToF数据
- Distance: 7361 距离数据，100倍mm距离值
- Temp:2735 温度数据，100倍摄氏度值
## 供电与数据
本项目支持12V/24V供电，默认编译选项为12V供电。主要相关部分为超声的驱动部分。
主要校准数据也会以12V为主。如果需要24V供电，请自行修改编译选项。
## 条件编译与输出
- 条件编译共有两个地方需要修改：
1. `ProjectDir/inc/ultrasonic_driver.h` 中配置12V/24V供电，默认为12V供电。
`#define POWER_SUPPLY_12V`
2. `ProjectDir/CMakeLists.txt` 中配置编译选项，默认为12V供电。
`set(POWER_VOLTAGE "12V")`
- 输出文件命名：
`XLSW_US-IR_FW_12V_V0.0.13_2024-x-x.bin/hex`
1. XLSW_US-IR_FW: 表示该项目为300K模拟超声波测距与IR非接触式测温方案的MCU固件
2. 12V: 表示目前编译固件为12V供电情况下优化的校正参数，建议与实际对应，这样可以获得更好的测距准确度
3. 2024-x-x: 表示编译日期
## TODO List
### 超声
- [x] 超声驱动信号（300KHz 50%duty 5cycles）发送
- [x] PA2/PA3配置为USART0
- [x] LED配置存活状态闪烁
- [x] 超声反射回波接受与精准计时
- 超声波反射回来后到sensor成功接收，GPIO上的反应主要分为两部分，
1. 超声波在发送时产生的余震，24V下大概为230us，12V下大概为210us。（前面所说的时间均为比较保守的时间）
2. 超声波会在接触到目标后反射回sensor上，并产生一个低电平，主要就是检测这部分。
- [x] 产生一个210-230us可调节的准确延时。（TIMER15配置为1us计一个数，设置重载为需要的时间，产生中断即可。）
- [x] 在产生指定时间的中断服务函数中，开启EXTI0（PA0,sensor信号接收引脚），开启TIMER14（计时计数器，1us计一个数，计算接收到外部中断的时间）
- [ ] 在外部中断服务函数中，产生一个事件或中断，进入到TIMER14的中断
- [x] TIMER14不存在F4x系列，改用TIMER16.
- [x] 放弃上述流程，多一层中断层，直接在EXTI0的中断服务函数中，直接读取TIMER16的CH_0计数值。
### IR
- [x] 配置IIC接口到PF0/1
- [x] 移植读取目标温度的函数
- [ ] 设置不同反射率下的校准
- [ ] 读取环境温度
### 条件编译
- [ ] 自动判断某一个条件编译是否开启，并在CmakeList中添加对应选项，输出文件时加以标识
- [ ] 超声反射回波接受与精准计时
