Vigenere
实现维吉尼亚密码,用键盘接收明文和密钥,屏幕打印密文和解密后的明文。
可以实现:大小写敏感,明文小写则密文大写,明文大写则密文小写输出,注意输入的健壮性控制,明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

STM32-USART-send-and-receive-data-
本程序目的是提供使用stm32串口收发一帧数据的一种方法,采用中断方式接受和发送,每进一次中断接收或发送一字节,可以实现pc机与板子通信或板子与板子间通信。注意本程序中外接高速晶振为12M赫兹,而大部分板子为8M赫兹,本程序所用芯片是stm32RBT6(The purpose of this procedure is to provide a method of using STM32 serial port to send and receive a data, using interrupt mode to receive and send, every one into the time interrupt receiving or sending a byte, can realize PC and the communication or board and board communication. Note that this procedure the external high-speed crystal oscillator for the 12M Hz, while the majority of board is 8M Hz, the chip used in this procedure is stm32RBT6)

1,、设置变量和参量:
X(n)为输入向量,或称为训练样本
W(n)为权值向量
e(n)为偏差
d(n)为期望输出
y(n)为实际输出
η为学习速率
n为迭代次数
2、初始化,赋给w(0)各一个较小的随机非零值,令n=0
3、对于一组输入样本x(n)和对应的期望输出d,计算
e(n)=d(n)-X^T(n)W(n)
W(n+1)=W(n)+ηX(n)e(n)
4、判断是否满足条件,若满足算法结束,若否n增加1,转入第3步继续执行(, set the variables and parameters:
X (n) is the input vector, otherwise known as the training sample
W (n) for the weight vector
e (n) for the deviation
d (n) is the desired output
y (n) is the actual output
η is the learning rate
n is the number of iterations)
