Description: Spartan 3 Digilent Demo:This demo drives the perphrials on the Spartan 3 board. This drives a simple pattern to the VGA port, connects the switches to the LEDs, buttons to each anode of the seven segment decoder. The seven segment decoder has a simple counter running on it, and when SW0 is in the up position the seven segment decoder will display scan codes from the PS2 port. This demo how ever does not drive the RS-232 port or the memory. This is a simple design done entirely VHDL not microblaze. Platform: |

Description: 7段数码显示译码器设计7段数码是纯组合电路,通常的小规模专用IC,如74或4000系列的器件只能作十进制BCD码译码,然而数字系统中的数据处理和运算都是二进制的,所以输出表达都是十六进制的,为了满足十六进制数的译码显示,最方便的方法就是利用译码程序在FPGA/CPLD中来实现。例子作为七段译码器,输出信号LED7S的7位分别接数码管的7个段,高位在左,低位在右。例如当LED7S输出为“1101101”时,数码管的7个段g、f、e、d、c、b、a分别接1、1、0、1、1、0、1;接有高电平的段发亮,于是数码管显示“5”。-7 digital display decoder design 7 Digital is pure combinational circuits, usually of small-scale dedicated IC, such as 74 or 4000 Series devices can only be used to decimal BCD decoder, but digital systems in the data processing and computing are binary, so the output expression are hexadecimal, and hexadecimal number in order to meet the needs of the decoding shows that the most convenient way is to use decoding process in FPGA/CPLD in to achieve. Seven-Segment decoder as an example, the output signal of the seven were LED7S access digital pipe 7 above, high in the left, low in the right. For example, when LED7S output as Platform: |

Description: 3位BCD码的计数显示电路。BCD码计数电路从0计到9然后返回到0从新计数。3位BCD码计数器可以实现从0到999的十进制计数。要将计数过程用七段显示LED数码管显示出来,这里采用动态分时总线切换电路对数码管进行扫描,对数码管依次分时选中进行输出计数的个、十、百位的数据。-3 BCD code count display circuit. BCD code counting circuit count from 0 to 9 and then back to 0 from the new count. 3 BCD code counter can be achieved from 0 to 999 decimal count. Counting process with seven segment displays to LED digital tube displays, where dynamic time-sharing digital bus switch circuit to scan, followed by time-sharing of digital output selected for a count of ten, hundred bits of data.
