单片机的实现多任务程序(8)

在51单片机如何实现多任务的程序

if (( Move_Num == 1 ) && ( CDis_Flag ))

XiSu_Dian = 1;

for ( i = 0;i < 20; i++);

Shi_bit = 1;

Ge_bit = 0;

Shu_Ma_Data = Led_Byte[SMG_Value[0]];

if (( Move_Num == 0 ) && ( CDis_Flag ))

XiSu_Dian = 1;

for ( i = 0;i < 20; i++);

Ge_bit = 1;

}

// 将主程序里面延迟时间在该子程序里面减去 循环时间 void Delay_Sub1(void)

{

if(Key1_Delay1 > Add_Ms)

Key1_Delay1 -= Add_Ms;

else

Key2_Delay1 -= Add_Ms;

else
