我要两路pwm输出移相，但是我配置了，还是两路一模一样，怎么回事啊-TI中文支持网

我这样配置 EPwm1Regs.TBCTL.bit.PHSEN = TB_ENABLE;
EPwm1Regs.TBPHS.half.TBPHS = 0;
EPwm2Regs.TBCTL.bit.PHSEN = TB_ENABLE ;
EPwm2Regs.TBPHS.half.TBPHS =100;

下面是我的初始化：

main里面：

EALLOW;
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 0;
EDIS;

InitEPwm1Example();
InitEPwm2Example();

EALLOW;
SysCtrlRegs.PCLKCR0.bit.TBCLKSYNC = 1;
EDIS;

void InitEPwm1Example()
{
EPwm1Regs.TBPRD = 600;

EPwm1Regs.TBCTR = 0x0000;

EPwm1Regs.CMPA.half.CMPA = 300;
EPwm1Regs.CMPB = 300;

EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
EPwm1Regs.TBCTL.bit.PHSEN = TB_ENABLE ;
EPwm1Regs.TBPHS.half.TBPHS = 0;
EPwm1Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1;
EPwm1Regs.TBCTL.bit.CLKDIV = TB_DIV1;

EPwm1Regs.CMPCTL.bit.SHDWAMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.SHDWBMODE = CC_SHADOW;
EPwm1Regs.CMPCTL.bit.LOADAMODE = CC_CTR_ZERO_PRD;
EPwm1Regs.CMPCTL.bit.LOADBMODE = CC_CTR_ZERO_PRD;

EPwm1Regs.AQCTLA.bit.CAU = AQ_CLEAR;
EPwm1Regs.AQCTLA.bit.CAD = AQ_SET;
EPwm1Regs.AQCTLB.bit.CAU = AQ_SET;
EPwm1Regs.AQCTLB.bit.CAD = AQ_CLEAR;

EPwm1Regs.ETSEL.bit.INTSEL = ET_CTR_ZERO;
EPwm1Regs.ETSEL.bit.INTEN = 1;
EPwm1Regs.ETPS.bit.INTPRD = ET_1ST;

}

void InitEPwm2Example()
{
EPwm2Regs.TBPRD = 600;

EPwm2Regs.TBCTR = 0x0000;

EPwm2Regs.CMPA.half.CMPA =300;
EPwm2Regs.CMPB = 300;

EPwm2Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN;
EPwm2Regs.TBCTL.bit.PHSEN = TB_ENABLE ;
EPwm2Regs.TBPHS.half.TBPHS =100;
EPwm2Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1;
EPwm2Regs.TBCTL.bit.CLKDIV = TB_DIV1;

EPwm2Regs.CMPCTL.bit.SHDWAMODE = CC_SHADOW;
EPwm2Regs.CMPCTL.bit.SHDWBMODE = CC_SHADOW;
EPwm2Regs.CMPCTL.bit.LOADAMODE = CC_CTR_ZERO_PRD;
EPwm2Regs.CMPCTL.bit.LOADBMODE = CC_CTR_ZERO_PRD;

EPwm2Regs.AQCTLA.bit.CAU = AQ_CLEAR;
EPwm2Regs.AQCTLA.bit.CAD =AQ_SET;
EPwm2Regs.AQCTLB.bit.CAU = AQ_SET;
EPwm2Regs.AQCTLB.bit.CAD = AQ_CLEAR;

EPwm2Regs.ETSEL.bit.INTSEL = ET_CTR_ZERO;
EPwm2Regs.ETSEL.bit.INTEN = 1;
EPwm2Regs.ETPS.bit.INTPRD = ET_1ST;

}

rookiecalf：

可以把波形也贴出来
