STM32知识每日更新
**Time:2024.4.281.GPIO端口进行编程作为模拟输入功能，内部操作包括:1.输出缓存器被禁止 2.施密特触发器输入停用，I/O引脚的每个模拟输入的功耗变为零 3.弱上拉和下拉电阻被关闭 4.对输入数据寄存器的读访问值为'0'2.stm32GPIO支持4种输出模式:开漏输出，开漏复用输出，推挽输出，推挽复用输出。 Tips: 下拉只能用来输入'
STM32GPIO支持三种最大翻转速度:2MHz,10Mhz,50Mhz，所以最大不能超过50Mhz， Tips:不存在GPIO_IN_INIT_LOW,实际上当引脚设置为输入时，其状态对应当时引脚外部的电平状态。
Vdd—-器件内部工作电压
VBAT—-电池工作模式专用引脚
VSS,VCC分别代表接地电压和输入电压
VEE—-负电压
flutter类的细节
Flutter近日学习所遇到的问题
是关于flutter里遇到的抽象类里面，关于继承和多态的应用。其中的语言是关于dart
首先，我创建一个class Person的类
1.第一种:继承---class Man extengds Person 对于它而言便是Person里面的方法以及属性都需要实现， 而第二种便是:多态---class Man implements Person，对于它来说是来实现接口的，若各位学有余力可以去自学一下"设计模式"这门课，废话不多说，我们来具体看看它的具体代码实现
比如说这个代码:1234567891011121314151617class person{ eat(); run(); //我在这里进行了抽象函数的设定}//然后我定义一个子类叫作manclass Man extends Person{ eat(){ print("我吃饭了"); //必须是具体的实现操作 } run() { print("吃 ...

POEM—-To find,and Not to yield2024-5-10 Some day I shall sing to you in the sunrise of some other world “I have seen you before in the light of the earth,in the love of man.” —-Tagore
2024-5-19 I love you,you are like the corolla of autumn candlelight of the light,and daily food in my empty soul.
2024-5-19 If you remember everything ,I wanted to say ,and if you are really like me ,then before you leave tomorrow,or when you are just ready to shut the door of the taxi and have already said goodbye ...
