51单片机实现数字时钟带闹钟 使用6个弹跳按钳和4个共阴七段显示器组合而成-51 MCU digital clock with alarm

这是用于proteus仿真软件的程序源码，当然也可以在单片机上用，请努力学习嵌入式吧-This is for the Proteus simulation software program source code, of course, can also be used in SCM, please study hard embedded bar

此程序是我用AT89S52单片机来控制显示屏FYD12864,采用C语言编写的可以显示图形,我调试了一周,在此和大家一起分享-this procedure is used to control the microcontroller AT89S52 FYD12864 screen, using the C language can display graphics, I debugged week, the share with everyone

该程序是AD9856的驱动部分，驱动部分调试通过，稍作修改即可运用在产品中-AD9856 The program is part of the drive, drive through part of debugging, with some slight modifications can be used in products

我用单片机8952和电压比较器339做了一个简单的电容容量测量表，参数大 致如下： 电容测量范围为1pF-9999.99uF，最小分辨力为1pF。分为5个量程，可以自 动切换量程，也可手动切换。 另外，有简单的频率计功能，能测量0-60MHz的数字信号频率（TTL电平）； 还可以产生几个单点频率的方波信号（比如1KHz）。 采用1602LCD作为显示器；4个按键控制；使用24C01保存当前设置值，不用 每次开机重新设置。可单5V供电，也可9V交流供电 -I used the single-chip 8952 and the voltage comparator 339 to do a simple capacitance measurement table, parameters are as follows: capacitance measurement range 1pF-9999.99uF, the minimum resolution for the 1pF. Divided into five ranges, you can automatically switch range can also be manually switched. In addition, a simple frequency meter function, capable of measuring 0-60MHz frequency digital signal (TTL level) can also lead to several single-point-frequency square-wave signal (for example, 1KHz). 1602LCD used as a monitor 4 button control use 24C01 to preserve the current settings, do not reset each boot. Can be a single 5V power supply, 9V AC power supply can also be

51单片机控制的红外遥控的接收部分的程序，可实现解调、解码和现实的功能，很实用！-51 MCU controlled by infrared remote control receiver part of the process, can be realized demodulation, decoding and realistic features, very practical!
