汇编中调用钩子函数的例子。-compilation called hook function examples.

晶振采用6M，P1口为数码管段输出口，P3.0~P3.2为数码管位输出口，P3.5超声波发送输出，P3.7超声波接收。

一个显示嚣控制程序，可以立即使显示器处于省电模工，用TASM32汇编的win32程序-a show clamor control procedures, can immediately display at a power-saving mode for use although the compilation process win32

hex 转 二进制-hex binary switch

运行可执行程序testword.exe，出现菜单主界面，按回车键出现由26个字母组成的乱序行，这时其中任一字母落下，在键盘上敲入该字母，如果输入正确，字母消失；按ESC键返回主界面；按空格见暂停；按‘E’退出。 -running executable testword.exe, there main menu interface, press the Enter key emerging from the 26 letters of the alphabet disorder OK, then any one of the letters fall into nice in the letter, if the importation is correct, the letters disappeared; According to the ESC key to return to the main interface; See box suspended by ; according to "E" withdrawal.

本实例可以实现数制转换，输入输出显示，大小写转换-This example system can achieve a number of conversion, input and output show that the conversion case

本程序采用了汇编语言实现HOOK技术，有完整源代码，采用RadASM进行工程组织-the procedures used assembly language to achieve HOOK technology, complete source code, RadASM used for engineering organizations

用汇编写的 CRC的算法代码，里面包含16位和32位的，大家可以嵌入到高级语言中使用，有助于提高程序的效率！内有嵌入例子。-With the compilation of the CRC algorithm to write the code, which contains 16-bit and 32-bit, and they can be embedded into high-level language used to enhance the efficiency of the procedure! Example, there are embedded.
