20bitBINtoBCD
- 在50MHz时钟下实现自增计数并驱动6位数码管进行显示-50MHz clock and drive six digital tube display increment count
led_key_beep
- 输入四路独立按键,输出四路独立LED和一个蜂鸣器。按下按键,对应的LED变量,同时蜂鸣器响,松开按键,对应的LED灭,蜂鸣器不响。蜂鸣器的功能是用四输入与门完成。这个四路很重要,整个电路扩展性很好。-Independent keys of the input four output four separate LED and a buzzer. Key is pressed, the corresponding LED variable, while the buzzer sounds, rel
fpxz
- 分频选择系统。inclk0端输入25MHz信号,通过altpll倍频为400MHz信号C0端输出,需求不一样自己改倍频器参数。分频器clkdiv用来二分频、四分频、八分频、十六分频,分别分频为200MHz、100MHz、50MHz、25MHz四种频率信号输入到选择器中。选择器的TCLK是外部输入信号,A[3..0]是四个独立按键,选择器是用按键的不同组合来从四个分频喜好和一个TCLK中选择一路输出。代码清晰易懂,不符合需求请自行扩展-Frequency selection system. the
pinlvji_LCD1602
- 一个完整的已经过测量和验证的VHDL程序,测量范围从1Hz到1GHz的频率计,也可以当做计数器,通过LCD1602显示频率值,四路独立按键可以控制输出不同的频率值、控制对应的独立LED亮灭、控制蜂鸣器发声。输入的晶振频率是25MHz,不符合请自行在倍频器中更改参数。-Has been a complete VHDL program measurement and verification, measurement range from 1Hz to 1GHz frequency counter
uartest
- uart发送模块测试,包含波特率转换和uart发送模块。系统时钟为50M。-uart transmit module test, including the baud rate conversion and the uart send module. The system clock is 50M.
cide_c2
- 以太网芯片dm9000a测试,程序配置了DM9000a,使该芯片完成以太网口的数据发送。-The Ethernet chips DM9000A test, the program is configured DM9000a, allows the chip to complete the Ethernet port to send data.
klt1
- klt算法的fpga实现,使用altera公司的开发环境。-the klt algorithm of the fpga implementation, altera company s development environment.
extreme_point
- 极值点遍历算法,将n次一维极值点遍历结果比较,输出。-Traversal algorithm for extreme points, the n-th one-dimensional extreme points traverse the results of the output.
clock2-
- 用硬件描述语言在modelsim中实现时钟的双边沿触发,分别在上升沿和下降沿都输出一个方波-Use hardware descr iption language in modelsim realized in the clock bilateral along the trigger, respectively, on the rise and decline of all along the output a square wave
gray_data
- 本程序可自动产生数据,存入存储器中并转化为格雷码,按时序输出。-This program can be automatically generates data such as the memory of deposit and translated into gray code, and the output time sequence.
