在有线电视中实现程控有源滤波器设计。为了充分利用设备和传输线,需要一种具有频率选择的网络―滤波器,将同一线 路上不同的信号分开,在电视机中也需要不同的滤波器(即选择有用信号,抑制无用信号) 。下面利用8051 单片机与12 位分辨率的DAC1208 数模转换芯片相结合的系统实现时间常数可程控有源滤波器设计,阐述了硬件结构与软件设计-In cable television in the realization of program-controlled active filter design. In order to make full use of equipment and transmission lines, the need for a frequency selective network- filter, the same lines separate different signal in the TV also requires a different filter (ie, choice of useful signals and suppress unwanted signals). Following the use of 8051 and 12-bit resolution digital-to-analog converter DAC1208 chip combining system time constant can be program-controlled active filter design, the hardware structure and software design

基于51单片机系统，实现能用接口1602 LCD的显示现控制。电脑主机通过串口给51发送控制指令，51根据指令对LCD进行相应的控制与显示操作。编程环境：Keil-Based on 51 single-chip system, 1602 LCD interface can display the current control. Mainframe computer through the serial port to send control commands 51, 51 follow the instructions on the LCD for the corresponding control and display operations. Programming Environment: Keil

软件中包含了Cypress的SL811 USB接口芯片的固件程序以及如何51单片机进行操作的例子，并且有Linux下的驱动程序，阅读并借鉴这个程序就可以做出支持USB HOST的系统了。-software includes the Cypress SL811 USB interface chip firmware procedures and how to 5 a microprocessor operating examples, as well as Linux drivers, read and learn from this procedure can make USB HOST support of the system.
