单片机计算机设计，实现加减乘除，包括小数点的运算，用的是4*4的键盘(Single chip computer design, realization add, subtract, multiply and divide, including the operations of the decimal point, with 4* 4 is the keyboard)

串口0通信-查询方式实验向串口发送子节数据，并等待数据发送完成，使用查询方式(Serial 0 communication- ways to experiment sub-section to the serial port to send data and wait for the data transmission is complete, use the query mode)

一个很实用的Listctrl，可以加图标（连Header都可以加图标），可以单Item的编辑，有下拉框，可以改变底色和文字颜色(A very practical Listctrl, can be added icon (with Header icon can be added), can single-Item editor, has drop-down box, you can change the background color and text color)

MICROSOT 做ACTIVE MOVE FLASH的东东,此说明是其SDK的一部份(MICROSOT make the ACTIVE MOVE FLASH Dongdong, this note is a part of its SDK)

pt100高精度测量电路，精度误差小，速度快，arm9 c51均可实现 ，仅供学习 参考(PT100 high precision measurement circuit, precision error is small, fast, C51 ARM9 can be achieved, only for learning reference )

超声波测距，可以通过串口助手显示，当小于设定值时，显示0，当大于设定值时，显示1(Ultrasonic Ranging, through serial aides showed that when less than the set value, 0, when greater than the set value, indicating a)

C8051F120和C8051F130的基础例程源码，学习该系列单片机的号资料(C8051F120 and C8051F130 source based routine, learning the number of the MCU data)

zigbee无线定位系统的相关程序代码。很有用 都有相关解释(zigbee location code)

说明：  51单片机用1602液晶显示串口接收到的数据(51 1602 MCU with LCD serial data received)

上位机，与51单片机进行通信，将从单片机发送过来获得的信息显示在显示界面上。(PC, with 51 single-chip communication, sent from the information obtained from the microcontroller is displayed on the display screen.)
