高精度频率计
本系统基于 C8051F020 实现等精度的频率测量， 利用该单片机灵活的控制功能及速
度优势，大大提高了性能和测量精度。以往的测频都是采用高频段直接计数、低频段间接测周
的方法，其测量精度往往会随着被测频率的改变而受到影响。为了克服测频中高低频段测量精
度不等的缺陷，采用双计数器设计，实现等精度的频率测量。等精度的测量方法不但具有较高
的测量精度，而且在整个测频区域内保持恒定的测量精度。

This program is in a room where a cat
本程序是在一个房间里猫捉老鼠的游戏。通过键盘上的上、下、左、右方向键控制一只猫，十只老鼠在窗口中自由活动，可随时改变行走方向，遇窗口边界则改变方向。猫碰到老鼠后就吃掉它（该鼠不再显示）。若猫吃掉所有老鼠，游戏结束并显示游戏所剩时间；若时间用完，猫没有吃掉所有老鼠， 游戏结束并显示所剩老鼠数目。-This program is in a room where a cat-and-mouse game. Through the keyboard up, down, left and right arrow keys to control a cat, 10 mice in the window to freely travel at any time to change the direction of the window border, however, to change the direction of the event. Encountered after the cat mouse eat it (the mouse is no longer displayed). If the cats eat all the rats, the game is over and displays the time remaining for the game if time runs out, the cat did not eat all the rats, the game is over and displays the number of the remaining mice.
