EP2C5T144 驱动 LCD1602液晶(LCD1602 LCD driver EP2C5T144)

本文设计了基于加速度传感器的计步器，并通过仿真以及实际调试得到了相应的结果的记录。本实验首先通过加速度传感器检测目标物体的运动，产生脉冲，将脉冲放大后经过施密特触发器整型为方波，并给出了方波的调试电路图。然后编写程序，利用D触发器检测方波的上升沿，当上升沿到来时，计数，并对十位、个位分别编码，然后由使能信号交替控制数码管输出结果。本文给出了仿真以及调试的程序、结果。(This article is designed pedometer-based acceleration sensor and the corresponding results recorded by simulation and debugging. The experiments by first acceleration sensor detects the movement of the target object, generates a pulse, the pulse amplification is a square wave after the Schmitt trigger integer, and gives the the debug circuit diagram of a square wave. Then write procedures, the use of the rising edge of the detection of the square wave of the D flip-flop, when the rising edge, the count, and ten bits are encoded, and then alternately by the enable signal output of the digital control. In this paper, a simulation and debugging procedures, results.)

说明：  采用FPGA（现场可编程门序列）编写VHDL语言设计多路同步脉冲发生器，对信号进行分频处理，实现四路信号相位相差T/16和T/8的延迟相位输出，实现的四路脉冲与传统的脉冲同步器不同，它具有高集成度，高通用性，容易调整和高可靠性等特点。(Using FPGA (field programmable gate sequence) to write VHDL language to design multi-channel synchronous pulse generator, to divide the frequency of the signal, to achieve the four-way signal phase difference T / 16 and T / 8 delay phase output, the realization of the four-way pulse is different from the traditional pulse synchronizer, it has the characteristics of high integration, high-throughput, easy adjustment and high reliability.)
