有没有人用过凌阳单片机？ 有没有知道凌阳61系列的单片机，在C编程时如何调用中断。。。 休 闲 居 编辑 >>>>>>>>休闲养生网回答： 我这里有一个定时器A的中断调用,程序本身你不需要去理解它到底想要做什么....你只需要参考下格式,大概就是这样的: #include"hardware.h" #include"unSPMACRO.h" main() { int a,b,c; INT_OFF(); *Port_IOA_Dir=0xffff; *Port_IOA_Attrib=0xffff; *Port_IOA_Data=0xffff; *Port_IOB_Dir=0xffff; *Port_IOB_Attrib=0xffff; *Port_IOB_Data=0x00ff; a=C_D8; c=C_B1; b=C_Fosc_256; *Port_TimerA_Ctrl=a+b+c; *Port_TimerA_Data=0xffff; *Port_INT_Ctrl=0x1000; INT_IRQ(); while(1) {*Port_Watchdog_Clear=0x0001; } } int a[200]={0xFFF0,0xFFEF,0xFFF1,0xFFEE,0xFFF1,0xFFED,0xFFF2,0xFFEC,0xFFF3,0xFFEB,0xFFF4,0xFFEA,0xFFF5,0xFFE9,0xFFF6,0xFFE8,0xFFF7,0xFFE8,0xFFF8,0xFFE7,0xFFF8,0xFFE6,0xFFF9,0xFFE5,0xFFFA,0xFFE5,0xFFFA,0xFFE4,0xFFFB,0xFFE3,0xFFFC,0xFFE3,0xFFFC,0xFFE2,0xFFFD,0xFFE2,0xFFFD,0xFFE2,0xFFFD,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE0,0xFFFE,0xFFE0,0xFFFE,0xFFE0,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFD,0xFFE2,0xFFFD,0xFFE2,0xFFFC,0xFFE3,0xFFFC,0xFFE3,0xFFFB,0xFFE4,0xFFFB,0xFFE4,0xFFFA,0xFFE5,0xFFF9,0xFFE6,0xFFF9,0xFFE6,0xFFF8,0xFFE7,0xFFF7,0xFFE8,0xFFF6,0xFFE9,0xFFF6,0xFFEA,0xFFF5,0xFFEB,0xFFF4,0xFFEB,0xFFF3,0xFFEC,0xFFF2,0xFFED,0xFFF1,0xFFEE,0xFFF0,0xFFEF,0xFFEF,0xFFF0,0xFFEE,0xFFF1,0xFFED,0xFFF2,0xFFEC,0xFFF3,0xFFEB,0xFFF4,0xFFEB,0xFFF5,0xFFEA,0xFFF6,0xFFE9,0xFFF6,0xFFE8,0xFFF7,0xFFE7,0xFFF8,0xFFE6,0xFFF9,0xFFE6,0xFFF9,0xFFE5,0xFFFA,0xFFE4,0xFFFB,0xFFE4,0xFFFB,0xFFE3,0xFFFC,0xFFE3,0xFFFC,0xFFE2,0xFFFD,0xFFE2,0xFFFD,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE0,0xFFFE,0xFFE0,0xFFFE,0xFFE0,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFE,0xFFE1,0xFFFD,0xFFE2,0xFFFD,0xFFE2,0xFFFD,0xFFE2,0xFFFC,0xFFE3,0xFFF7,0xFFE3,0xFFFB,0xFFE4,0xFFFA,0xFFE5,0xFFFA,0xFFE5,0xFFF9,0xFFE6,0xFFF8,0xFFE7,0xFFF8,0xFFE8,0xFFF7,0xFFE8,0xFFF6,0xFFE9,0xFFF5,0xFFEA,0xFFF4,0xFFEB,0xFFF3,0xFFEC,0xFFF2,0xFFED,0xFFF1,0xFFEE,0xFFF1,0xFFEF,0xFFF0}; int i=0; void IRQ1(void)__attribute__((ISR)); void IRQ1(void) { *Port_TimerA_Data=a[i]; i=i+1; if(i==200) {i=0;} *Port_IOA_Data^=0xffff; *Port_INT_Clear=0x1000; } |
