單片機(jī)源程序如下:
- #include "stm32f10x.h"
- uint16_t temp,i;
- uint8_t table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
- uint16_t disp[2];
- void Delay(unsigned int count)
- { unsigned int i;
- for(;count!=0;count--)
- { i=5000;
- while(i--);
- }
- }
- int main(void)
- {
- GPIO_InitTypeDef GPIO_InitStructure;
- RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOC,ENABLE);
- GPIO_InitStructure.GPIO_Pin=0xffff;
- GPIO_InitStructure.GPIO_Mode=GPIO_Mode_Out_PP;
- GPIO_InitStructure.GPIO_Speed=GPIO_Speed_50MHz;
- GPIO_Init(GPIOC,&GPIO_InitStructure);
- while(1)
- {
- for(i=0;i<=99;i++)
- {
- disp[1]=table[i/10];
- disp[0]=table[i%10];
- temp=(disp[1]<<8)|(disp[0]&0x0ff);
- GPIO_Write(GPIOC,temp);
- Delay(100);
- }
- }
- }
