通过单片机按键选择输出信号类型及要求输出量,在LED显示器件上指示信号类型及设定数值.系统工作电源±15V ， ±5V 。恒流电流输出0.0～8.0mA, 负载电阻≤500Ω。3． 稳压电压输出0.0～5.0V，电流负载能力≤100mA.电压及电流输出在充许负载范围内误差小于5％FS。电压及电流输出须共用一个输出正端, 输出负端为地。输出电压及电流设定精确到二位十进制数。 (Through Singlechip button to choose the type and requirements of the output signal output, in the LED display on the instructions of the signal type and set the value. System power supply ± 15V, ± 5V. Constant current output 0.0 ~ 8.0mA, the load resistance ≤ 500Ω. 3. Regulator output voltage 0.0 ~ 5.0V, current load capacity ≤ 100mA. Voltage and current output in the framework allow the load error is less than 5 FS. Output voltage and current output is required to share a client, the output of negative side for the land. Output voltage and current settings accurate to two decimal number.)

vc用驱动接口开发的,可以禁用usb,光驱,软驱,可以作为动态库使用.(vc-driven interface with development, you can disable the usb, drive, floppy drive, you can use as a dynamic library.)

本文系统的介绍了TQ2440开发板相关知识，对这方面的读者很有作用。(This article describes the system development board TQ2440 knowledge, useful in this respect the role of the reader.)

用VC++编写一个简单的基于UDP通信实例！实现了客户端与服务器端的通信源代码！(Using VC++ to write a simple UDP based communication instance! To achieve the client and server-side communication source code! )

端口扫描器。 本扫描器实现了：TCP Connect 扫描，TCP SYN扫描，TCP Fin扫描，TCP ACK扫描及UDP端口扫描,这些扫描能够实现扫描特定IP地址范围内端口和扫描某IP地址范围内全部主机特定端口两种模式，并且SYN扫描能够区分端口开放、端口关闭和被防火墙过滤三种状态。(Port scanner. The scanner realized: TCP Connect Scan, TCP SYN Scan, TCP Fin Scan, TCP ACK scan and UDP port scan, the scan can scan a specific IP address range of ports and scanning a range of IP addresses all host two specific ports mode, and can distinguish SYN scan open ports, port closed and the three states firewall filters.)
