[mw_shl_code=c,true]uCOS执行中断函数play1();完成后  跳不出switch函数  屏蔽 play1();以后就正常了 把play1();单独放在 一个任务函数里面的话开始任务就卡死 下面是主任务、play（）；和中断服务函数代码 纠结了老半天了 求大神们帮忙看看[/mw_shl_code] [mw_shl_code=c,true][/mw_shl_code] [mw_shl_code=c,true]void main_task(void *pdata) { // u16 key=0; // u8 err; // u8 res[5]; OSTaskSuspend(LED1_TASK_PRIO); OSTaskSuspend(LED2_TASK_PRIO); OSTaskSuspend(LED4_TASK_PRIO); OSTaskSuspend(LED5_TASK_PRIO); OSTaskSuspend(LED6_TASK_PRIO); OSTaskSuspend(LED7_TASK_PRIO); k=0; y1=150;y2=150; // u8 sem_led; //LCD_ShowNum1(40,70,Choose,4,Red,White); while(1) { LCD_ShowxNum(0,0,Res,2,16,16); LCD_ShowxNum(0,20,Main_Control,2,16,16); LCD_ShowxNum(0,40,First_One_Control,2,16,16); LCD_ShowxNum(0,60,First_Two_Control,2,16,16); LCD_ShowxNum(0,80,Second_One_Control,2,16,16); LCD_ShowxNum(0,100,Second_Two_Control,2,16,16); LCD_ShowxNum(0,120,Second_Three_Control,2,16,16); LCD_ShowxNum(0,140,Second_Four_Control,2,16,16); LCD_ShowxNum(0,180,Choose1,2,16,16); LCD_ShowxNum(0,200,Choose2,2,16,16); // key=(u32)OSMboxPend(msg_key,10,&err); switch(Res) //~~~~~~~~~~~~~~~~ { case 1: //×ó if(Main_Control==1) { if(Choose==0) { Right(); Choose++; } else { Left(); Choose--; } LCD_ShowxNum(10,20,Choose,2,16,16); } else if(First_One_Control==1) { if(Choose1==0) { Right(); Choose1++; } else { Left(); Choose1--; } } else if(First_Two_Control==1) { if(Choose2==0) { Right(); Choose2++; } else { Left(); Choose2--; } } Res=0; // OSTaskSuspend(LCD_TASK_PRIO); break; case 2: //??
