数字示波器实验，利用AD、DA和VGA三个外设来实现简易示波器，DA外设发送正弦波给AD外设，AD外设解析成数字信号将数据送给VGA外设进行显示。在VGA上可以看到DA外设发送的波形、波形频率和波形峰峰值。(In the experiment of digital oscilloscope, AD, DA and VGA are used to realize simple oscilloscope. DA peripheral transmits sine wave to AD peripheral. AD peripheral resolves into digital signal and sends data to VGA peripheral for display. The waveform, waveform frequency and peak value of DA peripheral can be seen on VGA.)

picoblaze实现串口通信...难道一定要20个字吗?-implement uart communication base on picoblaze

基于FPGA芯片，在Nios II IDE软件的开发环境下写的NIos II 软核uart源代码！-Based on FPGA chip, the Nios II IDE software development environment written in NIos II soft-core uart source code!

1．初始状态为4个方向的红灯全亮，时间1秒。 2．东、西方向绿灯亮，南、北方向红灯亮。东、西方向通车，时间30秒。 3．东、西方向黄灯闪烁，南、北方向红灯亮。时间2秒。 4．东、西方向红灯亮，南、北方向绿灯亮。南、北方向通车，时间15秒。 5．东、西方向红灯亮，南、北方向黄灯闪烁。时间2秒。 6．返回2，继续运行。 -1. Initial state for four whole direction of the red lights lit up, a second time. 2. East and West to the green, in the south, north to the red light. West and the East to open in time for 30 seconds. 3. East and West to the blinking yellow light, in the south, north to the red light. Time 2 seconds. 4. East and West to the red light, in the south, north to the green. South and North to the opening time of 15 seconds. 5. East and West to the red light, in the south, north to the flashing yellow light. Time 2 seconds. 6. Return 2, continued to operate.

设计一个由一条主干道和一条支干道的汇合点形成的十字交叉路口的交通灯控制器： 1)       主、支干道各设有3个方向的绿、黄、红指示灯（左转、直行和右转），每个行驶方向均配有时间显示数码管；2)       主干道处于常允许通行状态，而支干道有车来才允许通行（由外部信号通知）。3)       当主、支道均有车时，两者交替允许通行，主干道每次放行90s，支干道每次放行60s，在每次由亮绿灯变成亮红灯的转换过程中，要亮5s黄灯作为过渡，并进行减计时显示。

通信系统帧同步信号的设计与实现，巴克码识别器系统完整VHDL程序，本人课程设计，完全能正常运行，程序运行环境为Quartus II 7.2 (32-Bit)，win7系统。编译码模块、分频模块、门限设置模块、仿真电路和程序都有。相互交流，共同学习！！
