FPGA数码管显示秒表实验
说明: FPGA数码管显示秒表实验
三种方法实现:
方法一: 对秒计数,得到(秒显示)0~9,
对(秒显示)计数,得到(分秒显示)0~5,
对(分秒显示)计数,得到(分钟显示)0~5,
注意进位时机
方法二: 对秒计数,得到(秒显示)0~9
对秒计数,得到(分秒显示)0~5
对秒计数,得到(分钟显示)0~5
方法三:
只对秒计数,分别取模
%60得到分钟显示 ************************
余数%10得到分秒显示 (据说)取模运算占资源!!!!(也能接受?好像...)
再剩下的余数为秒显示 ************************(Experiment of Digital Tube Display Stopwatch Based on FPGA
Three ways to achieve)

mux21a
在VHDL结构体中用于描述逻辑功能和电路结构的语句分为顺序语句和并行语句两部分,顺序语句的执行方式十分类似于普通软件语言的程序执行方式,都是按照语句的前后排列方式顺序执行的。(VHDL structure in the body used to describe the logic function and circuit structure of the order of statements and expressions are divided into two parts in parallel statement, modalities for the implementation of the order of statement is very similar to ordinary language software program implementation, are in accordance with the statements before and after the arrangement of the order implementation.)

这是我的毕业设计的SVPWM使永磁交流同步电动机…
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
