wirebus总线nand flash controller

软件环境：TI的zstack协议栈 硬件：CC2530无线单片机 功能：利用超声波模块实现测距（该模块型号：HC-SR04 在淘宝上非常常见） 可测2厘米到3米距离(Software environment: TI' s zstack protocol stack hardware: CC2530 wireless microcontroller features: use of ultrasonic ranging module (the module Model: HC-SR04 on Taobao very common) can be measured 2 cm to 3 meters)

说明：  通过spi实现加速度计adxl357读取xyz三轴方向的加速度值(Accelerometers adxl357 read the acceleration value of XYZ three-axis direction through SPI)

本代码是异步FIFO的VERILOG HDL代码，代码除了实现基本的异步FIFO跨时钟域数据传输以外，代码简单易读，可以作为笔试或者面试手写代码的备考代码，本人华为FPGA逻辑开发工程师岗位面试手写的异步FIFO程序就是出自本代码

This is the update firmware for CVFX-C02, 7" motorized touch screen car dvd player gps

emmc控制芯片CMD命令线主机接口模块,(emmc control chip CMD command line host interface module)

8位并行输入的数转换成串行输出，是基于高级硬件编程语言VHDL编写的。(8-bit parallel input into serial output digital conversion is based on the high-level hardware programming language VHDL prepared.)

自己编写的C++的类的测试程序，有详细的注注释，对初学者有很大帮助！！！(The own written C++ class test program, detailed annotation of Note of great help for beginners! ! !)

这是一个LCD1602底层驱动代码，TI公司LM3S系列的(This is a LCD1602 underlying driver code, TI company LM3S series)

使用cordic算法，基于verilog实现的atan功能，经过仿真验证，适宜工程使用。(ATAN,implemented with cordic.)

采用xilinx的ROMIP核产生类似正弦信号，经过FFt后可以观察结果(Using the xilinx ROMIP nuclear generating similar sinusoidal signal can be observed through the results after FFt)
