摘要
为了实时获取生产线上大量按键并发动作状态,提出一种基于FPGA的多按键状态识别系统设计。该系统设计采用VHDL语言描述,有效地解决远距离、分散、多键并发状态识别问题,并减小电路板面积和单片机的信号连接,易于对大量按键并发输入操作。给出了该系统设计方案的硬件电路设计和仿真结果。该设计已成功应用于某项目中。
In order to real-time access to the concurrent action status of multiple keys in the production line,a new muhi-key action identification system is proposed based on FPGA device and VHDL language,which is an effective solution to the concurrent state identification of long-distance,scattered and multiple keys,as well as reduces the PCB area and the number of MCU＇s signal connections.The design has more superiority to such operations.The hardware circuit design and simulation results are given. The design has been successed application.
