功能： 1、作为下位机采集8255数据并将此数据通过通讯送出， 2、采集数据为BCD，先转换成二进制，处理后再转换成BCD 3、通讯采用方式3，多机通讯，上位机发地址时TB8=1，其他TB8=0 下位机SM2=1，RB8=1时产生中断后使SM2=0收发数据，结束后SM2=1-Features: 1, as under the 8255-bit machine data collection and communications sent through this data, 2, collected data for the BCD, first converted into binary, and then converted to deal with BCD 3, communication using methods 3, multi-machine communication, PC-fat address TB8 = 1, other TB8 = 0 under the digital machine SM2 = 1, RB8 = 1 when the failure to make SM2 = 0 to send and receive data, after the end of SM2 = 1

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
