This is common with the design of 51 series single

使用89S52设计的电子钟，C51 编写，本例没有使用1302等时钟芯片，但本例完全具有时钟芯片的功能。比如基本的年月日，时分秒和星期功能，而且还有平闰年的天数自动补偿。由于采用的是全软件算法，时钟误差较大，采用高质量晶振可以减少误差。本例重在培养与训练初学者对C51的学习。-89S52 designed using an electronic clock, C51 preparation, in this case did not use 1302 clock chip, etc., but in this case complete with a clock chip functions. For example the basic date, time, and every second week of features, but also the number of days flat leap automatic compensation. As a result of the full software algorithms, the clock error of greater use of high-quality crystal can reduce the error. In this case focuses on training and training for beginners to learn on the C51.

程序文件包括CMOS摄像头寄存器控制程序、VGA显示程序、IIC通讯协议程序，适用于一般图像传感器图像采集应用前端部分。读者可在此程序的基础上修改、添加内容以适合自己设计应用。

1．在发送端通过一个编码系统对待传数据预先编码，在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双向传输信息的通道），每端都需要一个完整的编/译 码系统。 2．本程序的目的是大大提高通信的信道利用率，缩短信息传输时间，降低传输成本。 -1. In the transmitter through a coding system for pre-treatment data-coding the receiving end of data from the decoding (recovery). For dual-channel (two-way transmission of information can access), each side needs a complete encoding/decoding system. 2. The procedures are designed to greatly enhance the communication channel utilization, reduced transmission time, and lower transmission costs.
