用单片机实现电子钟功能，供初学者学习单片机使用

8051微控制器上的 DES encryption/decryption used in IC smart cards. Software hasn t been validated and lacks in-line documentation.-8051 Microcontrollers on the DES encryption/decryption us ed in IC smart cards. Software hasn t been valida ted and lacks in-line documentation.

单片机C8051F221读取DS18B20温度值，温度显示在液晶屏屏LCM046上，单片机根据温度值来控制风扇的关和开。-C8051F221 Singlechip DS18B20 read temperature value, temperature displayed on the LCD screen LCM046, the single-chip microcomputer according to the temperature value to control the fan and open relationship.

本程序运行于C8051F330，功能为接收遥控器发出的红外信号，然后等待上位机通过I2C总线来读取。IR数据接收完毕后，不再采集新的IR数据，一直等待上位机将数据取走后才开始准备接收新的IR数据-this program running on the C8051F330, functional remote control device to receive the infrared signal, Then wait for the PC through the I2C bus to read. IR data receiving end, not the acquisition of new IR data have been waiting for the PC will be removed after data began preparing to receive the new IR data
