多个发光二极管封装在一起的七段数码显示器按其连接形式可分为共正极显示器和共负极显示器。图7-1所示的共阳极和共阴极七段数码管,除显示数字必须是七笔外,还提供小数点。共阳极显示器的阳极连接在一起,向阳极提供正电压,阴极由限流电阻控制为高电平或低电平,以确定其是暗还是亮。共阴极显示器的阴极连接在一起,...

I want to display different numbers on the 7-segment display of the altera de1 cyclone 2 board, but it has to be every second or every 2 seconds. For example at time t0 = 0s, number 1 should be displayed on the 7-seg display, at t1 = 1s or 2s, number...
If SW7 = 1 then use SW0, SW1, SW2 and SW3 to display the numbers 0 - 9 and the letters A, b, C, d, E and F (all the digits on the seven-segment should display) on your 7-seg display (Hex) I have a code but it is giving m...

下面分别举两个使用for循环语句的例子。 例1用for语句来初始化memory。 例2则用for循环语句来实现前面用repeat语句实现的乘法器。 [例1]: begin: init_mem reg[7:0] tempi; for(tempi=0;tempi<memsize;tempi=tempi+1) memory[tempi]=0; end
The purpose of this exercise is to learn how to connect simple input and output devices to an FPGA chip and implement a circuit that uses these devices.We will use the switches SW17−0on the DE2board as inputs to the circuit.We will use light emitting diodes(LEDs)and7-segment display...
