Verilog HDL编写的键盘扫描程序，考虑了判断按键弹起的问题。程序按一定的频率用低电平循环扫描行线，同时检测列线的状态，一旦判断有一列为低则表示有键被按下，停止扫描并保持当前行线的状态，再读取列线的状态从而得到当前按键的键码；等待按键弹起：检测到各列线都变成高点平后，重新开始扫描过程，等待下一次按键。-Written in Verilog HDL keyboard scanner, taking into account to determine key bounce problem. Program according to a certain frequency of scan lines with low-level circulation lines, while testing out the state line, once the judge has said there is a classified as low-key is pressed, stop the scan and to maintain the current line-line state, and then read out line state to get the current keys key codes to wait for key pop-up: To detect the lines at all out into a high level after the re-start the scanning process, waiting for the next key.

the CD
本CD-ROM包括《Verilog-HDL实践与应用系统设计》一书中的全部例子，这些例子全部通过了验证。第七章以后的设计实例，不仅有Verilog-HDL的例子，也附了包括VB、VC++等源程序,甚至将DLL的生成方法也详尽地作了说明。
-the CD-ROM include "Verilog-HDL Practice and Application System Design," a book the whole Examples of these examples were passed certification. After the seventh chapter, a design example is not only Verilog-HDL example, the report include VB, VC and other source files, even DLL generator also described in detail.
