这是点阵程序 个人认为先学点阵再学lcd比较好 p0 p2分别接16*16点阵的高八位和低八位(纵向取模) p3口低四位接4-16线译码器（74ls154）译码器低电平为列选 消除鬼影的方法：-This is the program individual lattice lattice before you think lcd is better to learn p0 p2, respectively, then 16* 16 lattice of high and low 8 8 (vertical modulus) p3 I received a low four 4-16 Line Decoder browser (74ls154) low-level decoder for the elimination of ghosting out the election approaches:

一种实现载波监听多点接入／冲突检测的多主RS485总线-A carrier sense realize multi-point access/Collision Detection RS485 multi-master bus

单片机程序，计算开关次数并保存次数，并能调用显示时间，清除纪录。-Single-chip process, calculating the number and save the number of switches, and can call the show time to clear the record.

LCD测试程序,内有键盘,显示等.大家不防看看.-LCD test procedure, which has a keyboard, display and so on. We do not look at the anti-.

AVR和PC机并口以EPP方式通信的源代码，与大家共享-AVR and the PC parallel port to EPP mode machine communication source code, and share

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
