代码大全，给我们提供了大量的单片机程序，除了学习外，还可缩减我们的开发时间...

数字电压表设计，单片机AT89S51与ADC0809设计，能够测量0－5V之间的直流电压值，四位数码显示。完整的C语言代码和电路图-Digital voltage meter design, microcontroller AT89S51 with ADC0809 design, capable of measuring between 0-5V DC voltage value, four digital display. Complete C language code and circuit diagram

一个本人编写的时钟程序，用stc芯片，四位数码管，74ls164译码器。-I prepared a clock procedures, using STC chips, four digital tube, 74ls164 decoder.

根据键盘的控制，移动字符串Hello或者华东师范大学,行列键盘的7用于字符串左移,8用于字符串下移，9用于字符串右移，5用于字符串上移。按键每按一下向各自的方向移动一个点阵的位置。-Under the control of the keyboard, move the string Hello, or East China Normal University, the ranks of the keyboard for the string to the left of 7, 8 for string down, 9 for string shifted to right, 5 for the string to move. Click the button for each move to their respective location of a dot matrix.

STM32电路图，有原理图和PCB，稍微处理即可直接去制作。-STM32 circuit, there is schematic and PCB, you can go straight to making a little deal.

单相电子式复费率电表解决方案,是很好的电表方案！也是很那找到的方案-Single-phase electronic multi-rate meter solutions, is a very good meter program! It is found that the program

44780字符液晶屏驱动演示程序总线方式-44,780 Character LCD Driver Bus Demonstration Program

实现电动机的软启动控制，modbus通信，LCD带字库显示，软件容错和抗干扰设计不错-Achieve soft-start motor control, modbus communication, LCD display with font, software fault-tolerance and anti-jamming design good

由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong

用C语言写的PS2代码，有比较好的通用性，并且在实际项目中用过-Using C language to write code of PS2, has a relatively good general, and used in actual projects
