基于FPGA的4＊4键盘扫描电路的改进设计
资料介绍
介绍了基于FPGA的4＊4键盘扫描电路的基本原理,并用VHDL语言对常见的设计方法进行了改进,使其更加稳定;通过＂组合键＂扩展了键盘编码,扩大了其适用范围;可作为基础输入模块,为其他模块提供有力的控制输入与数据输入支持.
This article deals not only with the introduction of the principle of scanning circuit for 4＊4 keyboard based on the FPGA,but also with the improvement of the common design by means of VHDL in order to make it more stable.With the design the keyboard code,together with its application range,has been extended by means of ＂Combination key＂.It can be used as a basis for input module,and provide a strong support of control input and data input for the other modules.
