Description: UART是一种广泛应用于短距离、低速、低成本通信的串行传输接口.由于常用UART芯片比较复杂且移植性差,提出一种采用可编程器件FPGA实现UART的方法, 实现了对UART的模块化设计.首先简要介绍UART的基本特点,然后依据其系统组成设计顶层模块,再采用有限状态机设计接收器模块和发送器模块,所有功能的实现全部采用VHDL进行描述,并用Modelsim软件对所有模块仿真实现.最后将UART的核心功能集成到FPGA上,使整体设计紧凑,小巧,实现的UART功能稳定、可靠. -UART is a widely used short-range, low-speed, low-cost serial transmission interface communication. Because of the complexity of common UART chip and poor transplant, using a programmable FPGA devices to achieve UART way of the realization of the UART modular design. First of all, a brief introduction of the basic characteristics of UART, and then according to their top-level module system design, and then the design of finite state machine receiver module and transmitter module, the realization of all the features to describe the use of VHDL and Modelsim software used Simulation of all modules. Finally, the UART core functionality into the FPGA, so that the overall design of compact, compact, the UART function of the realization of stable and reliable. Platform: |

Description: 为增加系统稳定性，减小电路板面积，提出一种基于FPGA的异步串行口IP核设计。该设计使用VHDL硬件描述语言时接收和发送模块在Xilinx ISE环境下设计与仿真。最后在FPGA上嵌入UART IP核实现电路的异步串行通信功能。该IP核具有模块化、兼容性和可配置性，可根据需要实现功能的升级、扩充和裁减。-In order to increase system stability, reduce board space, presents a FPGA-based asynchronous serial port IP-core design. The design using the VHDL hardware description language to receive and transmit modules in Xilinx ISE design and simulation environment. Finally, embedded UART IP core on the FPGA circuit implementation of the asynchronous serial communications. The IP core has a modular, compatibility and configurability, can achieve the functionality needed upgrade, expansion and reduction. Platform: |

Description: 本系统设计利用FPGA设计了一个接在电脑串口上的一个DMX512协议的转接卡，它可以让你的电脑变成一台超强的电脑灯控制台或者调光台、LED控制器等。通过电脑软件，可以控制电脑灯或者其他DMX512协议的设备，比如LED灯、激光灯、PAR灯、DJ设备等等。
本系统还有体积小巧携带方便等特点，足够一般的娱乐场所、多功能厅、会议厅等场所使用，同时采用电脑进行灯光的控制，也可以提升工程的技术含量，显得更高科技。通过简单更改DMX模块的UART部分，还可以将串口转换usb接口，不过由于手头上的FPGA开发板没有USB接口，所以使用UART接口进行测试。
-The system design using FPGA, a serial port on the computer then a DMX512 protocol adapter, it can make your computer into a super computer console or lighting console lights, LED controller. Through computer software, can control lights or other DMX512 protocol computer equipment, such as LED lights, laser lights, PAR lamps, DJ equipment. The system also features compact, portable and so on, is sufficient for most of the entertainment, function rooms, conference rooms and other places to use, while using computer control of lighting can also enhance the project s technical content, appears to higher technology. DMX module by simply changing the UART portion can also convert usb serial interface, however, because the FPGA development board on hand no USB interface, so tests using the UART interface.

Description: In embedded systems, the processor that we choose for our design may not come with built-in peripherals. Therefore, designers will have to implement these devices in hardware keeping in mind that they will need to interface to the processor. In this lab we will design a simplified UART (Universal Asynchronous Reciever Transmitter) in VHDL and download it to the FPGA on the XS40 baord.
Serial communication is often used either to control or to receive data from an embedded microprocessor. Serial communication is a form of I/O in which the bits of a byte begin transferred appear one after the other in a timed sequence on a single wire. Serial communication has become the standard for intercomputer communication. In this lab, we ll try to build a serial link between 8051 and PC using RS232.
