单片机是52的，P0口连到四个数码管的七个管脚，其中两个冒号点为最后两个数码管的DOP点，P1.0至P1.3为四个数码管的选通端，低电平有效。程序2较完整，可实...

avr单片机，4*4键盘源程序-avr microcontroller, 4* 4 keyboard source

遥控数字钟应用程序，应用于多种数字钟接口，可以遥控设备，省力。自制LED电子钟在很多电子报刊杂志上都可以见到，但大多数在断电后都要重新设置时间等 参数，给使用带来很多不便。也有用后备电池作为备用电源的，但往往体积较大。本文介绍 的LED电子钟克服了以往的弊端，而且采用了家电通用的红外遥控器进行控制，方便使用。 有一路闹铃输出，可以通过遥控器设置闹铃时间及允许与否。-digital clock remote control applications, digital clock used in a variety of interface, remote-control equipment, effort. Homemade LED electronic bell in many electronic newspapers and magazines can all, but most of the power outages after the re setup time and other parameters to use in many ways. Also useful as a standby battery backup power, but often larger. This paper introduces the LED electronic clock to overcome the shortcomings of the past, and the use of common household appliances infrared remote control, and ease of use. A way Alarms output, the remote control can set the alarm time and allow it or not.

太阳能充电与逆变控制包括电路图和值得参考的内容

DAC1230是一个12位的模数转换的芯片!而使用时候是在8位的单片机上运行,所以需要注意高四位和低八位的写入时序-DAC1230 is a 12-bit analog-digital conversion chips! Use of time in the 8-bit single-chip run, so it is necessary to pay attention to the high four and low eight write timing

使用89S52为核心做的USB键盘,注意修改了一下windows设备描述符以及端点处理等就行了。用了一个4*4的小键盘,有0-9十个数字键, Num Lock键,Caps Lock键,Shift键,Ctrl键,Alt键,回车键等。 最多可以有三个键同时按下，如果相交的话，最多只能两个键按下-89S52 use as the core of the USB keyboard to do, pay attention to modify the look and the windows device descriptor, such as treatment endpoint on the list. Used a 4* 4 small keyboard, has the number keys 0-9 10, Num Lock keys, Caps Lock key, Shift key, Ctrl key, Alt key, enter key and so on. Can have up to three keys pressed at the same time, if the intersection, then a maximum of only two keys pressed

自已编的程序.能通过RS485总线更新单片机中的应用程序,带一程序流程图和一些说明希望能对大家有所帮助!-Made their own procedures. Through RS485 Bus update MCU applications with a process flow chart and some that I hope can be helpful to everyone!

c8051f020 内部12位的ADC0 效果比较啊好,调通了 如果不行 我还有其他人写的一个程序.我传的代码都有比较爱完整的注释啊-C8051F020 within 12 compared the effect of the ADC0 ah well, if the transfer had not I still have other people write a program. I have compared the code Chuan Love Notes integrity ah
