在EPWM中初始化了各子模块，具体如下：
EPwm1Regs.TBPRD = 1500; //1430;// // 20kHz //1430=21k
EPwm1Regs.TBPHS.half.TBPHS = 0x0000; // Phase is 0
EPwm1Regs.TBCTR = 0x0000; // Clear counter
EPwm1Regs.TBCTL.bit.CTRMODE = TB_COUNT_UPDOWN; // Count up to down
EPwm1Regs.TBCTL.bit.PHSEN = TB_DISABLE; // Disable phase loading
EPwm1Regs.TBCTL.bit.HSPCLKDIV = TB_DIV1; // Clock ratio to SYSCLKOUT
EPwm1Regs.TBCTL.bit.CLKDIV = TB_DIV1; //
EPwm1Regs.TBCTL.bit.SYNCOSEL = TB_CTR_ZERO;
。。。。。。
if((wCurrentRef >= 2048) && (dwVoltOutTemp < 0)) //area4
{
if(dwVoltOutTemp > -50)
{
dwVoltOutTemp = -50;
}
EPwm1Regs.CMPA.half.CMPA = -dwVoltOutTemp;
EPwm1Regs.CMPB = 1500;
}
请问当条件满足时输出的模型是怎么样的？ |
