附录二：部分源程序
一、主函数源程序
#include \
u8 State_Machine = 6;//状态标志，初始化时自动跳转到桌面状态 void INIT_ALL(void);//硬件的所有初始化操作 u8 State6_zhuomian(void); int main(void) { INIT_ALL();
Acquisition_Calibration();//获得触摸屏校准参数 while(1) {
switch(State_Machine) {
case 0:State_Machine = State0_Calendar();//万年历
break;
case 1:State_Machine = State1_Clock();//闹钟
break;
case 2: State_Machine = State2_Stopwatch();//计时器
break;
case 3: State_Machine = State3_Map();//地图
break;
case 4: State_Machine = State4_Drawing_Board();//画板
break;
case 5: State_Machine = State5_Pedometer();//计步 break;
case 6: State_Machine = State6_zhuomian();//桌面
}
}
} 二、桌面状态源程序
