函数是 C 中最常用的结构概念。它们应用于实现“自顶向下的”问题解决方法 ― 即，将问题分解成越来越小的子问题，直到每个子问题都能够用代码表示。这对程序的模块化...

在STM32单片机上实现长按4S按键进入待机模式，并且可以用RTC报警唤醒单片机(In the STM32 microcontroller to achieve long press 4S button to enter standby mode, and you can wake up with a single-chip RTC alarm)

说明：  硬件资源: 1,DS0(连接在PA8)，DS1(连接在PD2上) 2,串口1(波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面) 3,ALIENTEK 2.8/3.5/4.3寸LCD模块(仅支持MCU屏) 4,按键KEY0(PC5)/KEY1(PA15)/KEY_UP(PA0,也称之为WK_UP) 实验现象: 按下KEY_UP键申请内存，内存申请成功以后就可以使用了，按下KEY0键 就是使用申请到的内存。当内存使用完成以后就可以按KEY1键将内存 释放掉。(Hardware resources: 1, DS0 (connected to PA8), DS1 (connected to PD2) 2. Serial port 1 (baud rate: 115200, PA9/PA10 connected on board USB to serial chip CH340) 3, ALIENTEK 2.8/3.5/4.3 inch LCD module (only supporting MCU screen) 4. Keyboard KEY0 (PC5)/KEY1 (PA15)/KEY_UP (PA0, also known as WK_UP) Experimental phenomena: Press KEY_UP key to apply for memory, memory application can be used after success, press KEY0 key That is to use the applied memory. When the use of memory is complete, you can press KEY1 to store the memory. Release.)

《算法导论》，是一本十分经典的计算机算法书籍，与高德纳（Donald E.Knuth）的《计算机程序设计艺术》（《The Art Of Computer Programming》）相媲美。 《算法导论》由Thomas H.Cormen、Charles E.Leiserson、Ronald L.Rivest、Clifford Stein四人合作编著（其中Clifford Stein是第二版开始参与的合著者）。本书的最大特点就是将严谨性和全面性融入在了一起。(原书名——《Introduction to Algorithms》)
