用proteus仿真的数字电压表 有8051单片机和adc0809以及4位数码管实现...

PC机与单片机串口通讯可以通过多种方式来实现，在这里只介绍使用MSCOMM控件进行通讯。-PC and microcontroller serial communications to be many ways to achieve here in only MSCOMM controls on the use of communication.

完全正确的频率计供大家参考（1602显示),非常适合单片机学习和使用-Completely correct frequency for your reference (1602 show), very suitable for the learning and use of single-chip microcomputer

C8051f020是基于51核的业界8位单片机最高速的，指令执行速度25MIPS。这个程序包是新华龙公司提供的，需要购买900元的开发系统才会赠送此文件包，先上传。可以用keil软件打开或者去www.xhl.com.cn下载IDE软件打开工程ps－－－c文件直接用记事本就ok啦^_^，里面有温度传感，步进电机等等源代码，方面移植！^_^-C8051f020 is based on the 51 nuclear industry eight most high-speed microcontroller, instruction execution speed MIPs. This package is a new company providing the Hualong, you need to buy 900 yuan development system will give this package, the first upload. Keil software can be used to open or download IDE www.xhl.com.cn open software engineering-- c ps documents directly on the notebook ok-- ^ _ ^, inside temperature sensor, stepper motors, etc. source code, area transplant! ^ _ ^

单斜率模拟数字（ A / D转换）演示代码-Single-Slope Analog-to-Digital (A/D) Conversion

这是电容的制作图，我们可以用单片机作一个电容表，这样就可以测量一些没有标明的电容-This is the capacitance of the production of maps, we can use single-chip capacitance for a table, so that can be measured are not marked with the capacitance

拷拷贝到你的Keil安装目录下的c51in文件夹中。 工程文件中需设置一下: project->Option for Target Target1 选Debug页 左侧最下面 Dialog Dll 一般是DP51.DLL，不用修改 Parameter 中是 -P51 在其后加入 -dledkey 即该行看起来应该是这样的： -p51 -dledkey 保存即可 进入调试后，点击：Peripherals，其中多出一个“键盘LED实验仿真板”选择该项即可。-emboss your copy of the Keil installation directory under the decoder bin folder. The project document to be provided as follows : project-gt; Option for Target Target1 election Debug bottom of the left page is generally Dialog Dll DP51.DLL, need not be amended Parameter is- P51 add after-dledkey that the bank should look like this :-p51-can be preserved into dledkey to debug and click : Peripherals, in which more than a "keyboard LED simulation board," which can be chosen.

8*8键盘检测，我用keilc进行开发的-8* 8 keyboard detection, I used to carry out the development of keilc

实时时钟M41T0源程序,你只要定议好引脚,便能使用,主程序是一个应用试验-M41T0 real-time clock source, as long as you set a good discussion pin can use, the main program is a pilot application

利用单片机实现简单音乐发生器，可以尝试实践一下，比较简单-MCU use simple music generator, may try to practice that is relatively simple
