lax-wendroff求前台阶超声速流动(lax-wendroff format)

使用51单片机，用其内部定时中断，和外部中断只找一个可控脉宽调制信号PWM(Using 51, with its internal timer interrupt, and external interrupt only to find a controllable pulse width modulation signal PWM)

stm32，通过spi总线实现对于TI的2543AD进行读写操作，串口uart输出数据(stm32, achieved through the spi bus for read and write to TI s 2543AD, serial uart output data)

基于STM32的双串口通信程序，能实现两个串口的收发，程序默认采用串口2接收数据，串口1发送(Based on the STM32 dual serial communication procedures, can achieve two serial transceivers, the program defaults to the serial port 2 receives the data, send the serial port 1)

使用DataAdapter对数据库进行操作 将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作. 程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object. )

固高运动控制卡GE-400-SG随机光盘(GoogolTech GE-400-SG accompany CD)

将十进制数转换为二进制数和16进制数，可用于单片机初值设定时的计算(convert decimal to binary and hexadecimal ，Can be used to calculate the initial set of single chip microcomputer)

C++ SDK绘图。涉及函数：WinProc Draw(C++ SDK graphics. Related to function: WinProc Draw)

电子万年历设计，有程序和电路图，已经经过调试成功，希望对需要的人们，提供这一资料(Electronic calendar design, there are programs and schematics, has been successful commissioning hope that people need to provide this information)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)
