用单片机C语言编的日历芯片PCF8563的实时时间显示C程序源代码，可供单片机开发人员参考。-MCU series of the C language PCF8563 calendar chip real-time hours of C source code available to developers SCM reference.

说明：此程序使用标准PS2键盘输入，LCD1602液晶屏输出显示。此样例仅作测试使用 晶振使用12M或者11.0592M,本键盘使用部分字母和数字测试，其他按键不能使用，用 户可以自行扩展。由于开发板和程序的各种参数，程序中没有使用奇偶校验，不保证没有 误码,校验程序请自行添加。-Description: This program uses the standard PS2 keyboard input, LCD1602 LCD output display. This sample is only used for testing the use of crystal 12M or 11.0592M, this keyboard to use part of letters and numbers tests, other buttons can not be used, users can expand their own. As the development board and procedures for various parameters, the program does not use parity, does not guarantee that there is no error, verification procedures to add your own.

51开发板仿真平台提供的串口调试软件(sscom32.exe)和虚拟串口软件 (vspdxp.exe)，-51 development board to provide the serial simulation platform debugging software (sscom32.exe) and virtual serial port software (vspdxp.exe),

HMC6253 interfacing with atmega

非常好的项目代码，对你来说可以说是可遇不可求的代码-A very good project code, for you can be said that the code can not make the event

单片机串口程序，有一定的难度，适合串口使用比较熟练的人-Single-chip serial procedures, have a certain degree of difficulty, suitable for serial use more skilled people

这个程序是控制2401模块一直发送字节，和上一次的可以配合使用，实现发射接收并且上传到电脑串口-This procedure is to control module has been sent 2401-byte, and the last can be used in conjunction to achieve the launch reception and uploaded to the computer serial port

比较经典的独立键盘及时扫描方法。51单片机中运行-Comparison of classic and timely independent keyboard scanning method. 51 Single-chip running

利用51单片机及其接口电路模拟DMA的控制过程，由于数据的传输实际上不经过CPU而直接由A/D转换芯片传送到存储器，从而实现了数据的高速传送。-The use of 51 single-chip circuit simulation and its interface DMA control process, because the data transmission does not actually read the CPU and directly from the A/D conversion chip is sent to memory, thus realizing high-speed data transmission.

DS18B20实时测量温度，并通过单片机控制显示，显示装置用数码管 -DS18B20 real-time measurement of temperature, and through single-chip control shows that display devices with digital control
