本次实验是为了了解RT-thread的工作流程以及简单的实验RT来进行一个学习
实验材料：STM32c8t6+1.44寸TFT显示屏+红外传感器+分光棱镜
实验结果：可以进行红外定时选择，实验成功分为三个线程做任务
线程一：开机时间显示
//APP1

Demo_Menu();
while (1)
{

second++;
}
else
{

munite++;
if(munite==60)
{
second=0;
munite=0;
hour++;
if(hour==24)

hour=0;
}
}
}
sprintf(dispBuff,"-%02d:%02d:%02d-",hour,munite,second);
Draw_Font24B(4,30,RED,dispBuff);
// Draw_Font16B(4,40,YELLOW,dispBuff);//8*16 “ABC”
rt_thread_delay(1000); /* 延时500个tick */
}
}?线程二：红外遥控判断
