关于28335编译

while(Ecap1Regs.ECFLG.bit.CEVT1!=1){}
Tst1=Ecap1Regs.CAP1;
while(Ecap1Regs.ECFLG.bit.CEVT2!=1){}
Tst2=Ecap1Regs.CAP2; //检测周期

while(Ecap2Regs.ECFLG.bit.CEVT1!=1){}
Tst3=Ecap2Regs.CAP1;
while(Ecap2Regs.ECFLG.bit.CEVT2!=1){}
Tst4=Ecap2Regs.CAP2; //检测周期;

error #20: identifier "Ecap1Regs" is undefined
 error #20: identifier "Ecap2Regs" is undefined

编译时为什么这个会出现未定义呢

我有对ECAP1ECAP2进行初始化了

回复 Eric Ma:

我在这个文件里看到了这个

//—————————————-#ifdef __cplusplus#pragma DATA_SECTION("ECap1RegsFile")#else#pragma DATA_SECTION(ECap1Regs,"ECap1RegsFile");#endifvolatile struct ECAP_REGS ECap1Regs;

//—————————————-#ifdef __cplusplus#pragma DATA_SECTION("ECap2RegsFile")#else#pragma DATA_SECTION(ECap2Regs,"ECap2RegsFile");#endifvolatile struct ECAP_REGS ECap2Regs;

原来是我把ECap写成Ecap了.. 谢谢你Eric
