买的一块开发板的开发文档、原理图还有PCB板，并且附有PCI9054的驱动程序及上位机测试应用程序，调试时需要安装Windriver。(Development board to buy a piece of the development of documents, there are PCB board schematics, and with the PCI9054 PC drivers and test applications, when the need to install debug Windriver.)

基于STC89C52写的蜂鸣器唱歌程序，可以控制开发板上的蜂鸣器唱歌，适合初学者(Based on the STC89C52 write buzzer singing procedures, can control the development board of the buzzer singing, suitable for beginners)

PIC （PIC16F886） 做的简单频率计 用TMR0定时1s，将待测信号从T1CKI脚输入，用TMR1进行计数，读出TMR1H，TMR1L的值就是频率 单片机：PIC16F886 显示：LCD1602 编程语言：PIC C 附Proteus仿真。(PIC (PIC16F886) to do a simple frequency counter TMR0 timer with 1s, the test signal input pin from T1CKI with TMR1 count, read TMR1H, TMR1L value is the frequency of the microcontroller: PIC16F886 display: LCD1602 with Proteus simulation.)

at89c52的示例程序，简单的介绍了led的是使用(At89c52 example program, little led is used)

铸造过程中温度场的描述的仿真模拟，可以写到文件中(Casting process described temperature field can be written to a file)

一个电表行业专用的基于645规约的电表485通讯抄表程序，可以进行485总线抄表，645规约测试。程序技术要点就是规约数据传输协议的处理，如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)

新华龙公司c8051f源码，用于cp2200(Hualong company c8051f source for cp2200)

51单片机的闪烁灯代码一，非常适合初学者的使用，在这分享给大家。(51 MCU flashing lights code, very suitable for beginners to use, in this share to everyone. )

3． 参考void Reverse(LinkQueue &Q)函数，定义新的函数int Palindrome_Test(char str[])，判断字符串str是否回文序列,若是则返回1,否则返回0。写出程序或用文字描述算法的执行步骤。(3. Reference void Reverse (LinkQueue & Q) function, define a new function int Palindrome_Test (char str []), to determine whether the string str palindromic sequence, if it returns 1, otherwise it returns 0. Written procedures or describe in words the steps of the algorithm.)
