本人编写的FPGA光电编码器输入模块,没有实验,但仿真基本实现,希望有参考价值.-FPGA optical encoder input module, there is no experimental, but simulation technology, hope to have reference value.

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.

温度监视器，通过按键来设定温度上下限，用DB18B20来显示温度，越限灯亮，蜂鸣器响，在KEILC下编译调试成功-Temperature monitor, through the button to set the temperature of the upper and lower limits, DB18B20 used to display the temperature, the more limited light, buzzer sound, in the debug compile successfully under KEILC
