uart implementation and documentation, this describes the basic steps in building your own uart module on verilog and programming them on an fpga device

1、用状态机设计A/D转换器ADC0809的采样控制电路，并在数码管上显示转换结果； 2、设置有复位和启动/保持开关，要求 ⑴ 复位开关用来使A/D转换器复位，并做好A/D转换准备； ⑵ 启动/保持开关用来控制A/D转换器开始连续转换或停止转换保持结果，即按一下启动/保持开关，启动A/D转换器开始转换，再按一下启/停开关，停止转换并保持结果。 3、采用Verilog HDL语言设计符合上述功能要求的控制电路。(1, with the state machine design A/D converter ADC0809 sampling control circuit and display the results on the digital conversion 2 is provided with a reset and start/hold switch, reset switch is used to make the request ⑴ A/D converter reset and do A/D conversion ready ⑵ start/hold switch is used to control the A/D converter starts converting or stop the conversion to maintain a continuous result that by clicking Start/hold switch, start the A/D converter to start the conversion, and then Click the start/stop switch stops the conversion and keep the results. 3, using Verilog HDL language designed to meet the functional requirements of the above-mentioned control circuit.)

卫星信道模拟器能够模拟卫星信道的传播特性，用于设备的通信调试，节 约研发成本。目前，很多卫星信道模拟器在参数设置上存在问题：有的参数难 以调节；有的采用上位机进行参数设置，通过上位机设置参数需要连接电脑， 适应性差。针对上述问题提出了一种基于FPGA可触控卫星信道模拟器，FPGA 作为算法实现和控制单元，通过控制触摸屏方便快捷的实现参数设置。(Literature of Satellite Channel Simulation Based on FPGA)
