基于EPM1270

This tutorial explains how the SDRAM chip on ltera’s DE2 Development and Education board can be used with a Nios II system implemented by using the Altera SOPC Builder.

这是我毕业设计做的一个SVPWM同步永磁交流电机的控制系统，里面除了一个SVPWM的驱动算法之外，还有一个步进电机的控制器，以及基于QUARTUS7.2的NIOS II控制核心，通过PC的串口可以控制同步永磁交流电机和步进电机进行精确的定位。该系统较复杂，运用的知识也比较多，在SVPWM算法，PID算法，步进电机控制方面，NIOS II的串口编程等都有值得参考的地方。最好使用QUARTUS7.2编译，目标芯片是选用EP1C6Q240-This is my graduation project SVPWM make a permanent magnet AC synchronous motor control system, which apart from a driver SVPWM algorithm, there is a stepper motor controller, as well as QUARTUS7.2 based on the NIOS II control core, through PC serial port can be controlled permanent magnet AC synchronous motor and stepper motor for accurate positioning. The system is more complicated, the use of more knowledge, in the SVPWM algorithm, PID algorithm, stepper motor control, NIOS II serial programming, such as places are worth considering. QUARTUS7.2 compile the best use of the target chip is optional EP1C6Q240

ModelSim的波形比较的功能可以将当前仿真与一个参考数据（WLF文件）进行比较，比较的结果可以在波形窗口或者列表窗口中查看，也可以将比较的结果生成一个文本文件-ModelSim waveform can be compared to the current functional simulation with a reference (WLF paper ), the results can be compared in the waveform window or window List View, it will also compare the results generate a text file

这是我用vhdl语言，在fpga内部做了一个双口ram的程序。我的邮箱：wleechina@163.com-This is the language I used vhdl in fpga done an internal dual-port ram procedures. My mail : wleechina@163.com

用VHDL语言实现一个能显示时、分、秒的时钟：可分别进行时和分的手动校正；12小时、24小时计时制可选，12小时制时有上下午指示；当计时到预定时间（此时间可手动设置）时，扬声器发出闹铃信号，闹铃时间为10秒，可提前终止闹铃。-VHDL language used to achieve a display hours, minutes and seconds of the clock: when can be manually corrected and points 12 hours, optional 24-hour time system, 12-hour on the afternoon of instructions from time to time when the time to the scheduled time (This time can be manually set), the speaker sent alarm signals, alarm time was 10 seconds, the alarm can be terminated prematurely.
