这是一个51单片机控制语音芯片ISD33240放音的一端程序…

时钟芯片12c887非常实用，现奉上它的程序仅供参考。-12c887 chip clock is very useful, now offering its program is for reference only.

51系列单片机实验课程：串口 （通过计算机与试验箱相连，互相收发信息）-51 Series single-chip experimental curriculum: serial (through the computer and the chamber connected to each other to send and receive information)

实时时钟芯片DS1302的C51程序-real-time clock chip DS1302 the procedures C51

利用动态扫描和定时器1在数码管上显示 出从765432开始以1/10秒的速度往下递减 直至765398并保持显示此数，与此同时利 用定时器0以500MS速度进行流水灯从上至 下移动，当数码管上数减到停止时，实验 板上流水灯也停止然后全部开始闪烁，3秒 后（用T0定时）流水灯全部关闭、数码管上 显示出"HELLO"。到此保持住。 设晶振频率为12MHz。-The use of dynamic scanning and Timer 1 in the digital control to show from the beginning of 765,432 to 1/10 seconds until the speed of descending down 765,398 and maintain display this number, at the same time the use of Timer 0 to 500ms the speed of light from the flowing water to Under the move, when reduced to a few digital tube stop, the experiment on-board water stop and then all the lights started to flicker, 3 seconds later (T0 regularly used) closed water lights, digital tubes show
