学EDA时做的实验，工具为QuartusII7.0 ，使用VHDL语言，编完后下载到LED板上实现要求的功能——计数，时钟，循环显示。

m32f103r6仿真计数器程序+Proteus 单片机源程序如下: #include "stm32f10x.h" #include "Delay.h" #include "smg.h" #include "sys.h" #include "timer.h" #include "led.h" #include "fmq.h" #include "key.h" #include "stm32f10x_tim.h" uint16_t table[] = { /* 0, 1, 2, 3, 4, 5, 6, 7, 8, */ 0x3F, 0x06, 0x5B, 0x4F, 0x66, 0x6D, 0x7D, 0x07, 0x7F, /* 9, A, B, C, D, E, F, ., none */ 0x6F, 0x77, 0x7C, 0x39, 0x5E, 0x79, 0x71, 0x80, 0x00 }; uint16_t t; uint16_t num[3],inc = 0x00; int main(void) { SMG_Init(); GPIO_Write(GPIOA, 0x3f3f); GPIO_Write(GPIOB, 0xff3f); while (1) { t=KEY_Scan_KEY_INC(); //得到键值 if(t) //if(条件)t!=0真 { inc++; if(inc <= 0xff) { num[2]=inc%10; num[1]=inc/10%10; num[0]=inc/100; GPIO_Write(GPIOB,((~inc) <<8) + table[num[2]]); GPIO_Write(GPIOA,(table[num[1]] <<8) + table[num[0]]); } else { inc = 0xff; } } } }
