28335进入中断后给片选空间赋值

定时器, 空间, 软件

主要代码如下，为什么我把&nbsp;&nbsp;*ExRamStart=i&nbsp;&nbsp;注释掉之后就可以进入中断函数，可以仿真运行，LED闪烁正常；而未注释掉就不能进入中断函数了，仿真运行时软件卡死？

Uint16&nbsp; &nbsp; *ExRamStart = (Uint16 *)0x274000;//操作地址
Uint16 i=0x00;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;//变量

interrupt void ISRTimer0(void)&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp; //定时器0中断函数
{
&nbsp; &nbsp; CpuTimer0.InterruptCount++;
&nbsp; &nbsp; PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;
&nbsp; &nbsp; CpuTimer0Regs.TCR.bit.TIF=1;&nbsp; &nbsp;&nbsp; &nbsp;
&nbsp; &nbsp; CpuTimer0Regs.TCR.bit.TRB=1;

&nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;LED1=~LED1;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;&nbsp; &nbsp;//指示灯
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;
&nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; i++;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(i==0x3f)
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; i=0x00;
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }

&nbsp; &nbsp; &nbsp; &nbsp; //&nbsp; &nbsp; &nbsp; &nbsp; *ExRamStart=i;&nbsp; &nbsp;&nbsp; &nbsp; // 在这个地址中写入变量i

}
