FPGA部分源代码，关于dsp48的应用，从一本很好的书上下的

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.)

篮球24s计时。计时器递减计数到零时，数码显示器显示‘0’并停止，同时发出报警信号(basketball 24 seconds)

网上分享的一段100例子，适合FPGA学习的初学者。内部还有一些经典实用技巧。                                                                        

可以用于按键去抖动的电路应用，采用vhdl编写-Button can be used to jitter circuit applications, the preparation of the use of VHDL

例程是基于quartus的，FPGA通过EMIF给DSP发送数据，里面包含了一个简单的状态机和一个基于IP核的fifo，适合初学者(Routine is the FPGA to send data to the DSP via EMIF, which contains a simple state machine and an IP-based core fifo, suitable for beginners)

FPGA SPI 主要模块全部涵盖 时序解释 与DSP通信(FPGA SPI Timing interpretation covering all main modules communicate with the DSP)

说明：  内附几十种小程序，有状态机、比较器、波形发生器、乘法器、加法器、步进电机控制器等，希望大家能用的上。(Containing dozens of small programs, for reference，This is about FPGA,a tool ,we can study,but in ourselves.)
