DSP tms 28335 以下epwm配置能不能实现电流滞环控制以及软件强制输出6路pwm

[qq_42156112]

求各位懂DSP得大佬帮助下
这是关于软件强制输出高低电平的配置 ：

下面是电流滞环的逻辑
void F2833X_PWM_Update(PWMGEN *p)
{

float32 A;
float32 B;
float32 C;
A=(float32)p->MfuncC4 - (float32)p->MfuncC1;//C1,C2,C3是指输入电流 , C4，C5，C6是指反馈电流
B=(float32)p->MfuncC5 -(float32) p->MfuncC2;
C=(float32)p->MfuncC6 -(float32) p->MfuncC3;

if( A>=0.316)
{
EPwm1Regs.AQCSFRC.bit.CSFA = 1; // Forcing a continuous Low on output A of EPWM1
EPwm1Regs.AQCSFRC.bit.CSFB = 2;
}
else
{

EPwm1Regs.AQCSFRC.bit.CSFA = 2; // Forcing a continuous Low on output A of EPWM1
EPwm1Regs.AQCSFRC.bit.CSFB = 1;
}

if( B>=0.316)
{
EPwm2Regs.AQCSFRC.bit.CSFA = 1; // Forcing a continuous Low on output A of EPWM1
EPwm2Regs.AQCSFRC.bit.CSFB = 2;

}
else
{
EPwm2Regs.AQCSFRC.bit.CSFA = 2; // Forcing a continuous Low on output A of EPWM1
EPwm2Regs.AQCSFRC.bit.CSFB = 1;

}

if( C>=0.316)
{
EPwm3Regs.AQCSFRC.bit.CSFA = 1; // Forcing a continuous Low on output A of EPWM1
EPwm3Regs.AQCSFRC.bit.CSFB = 2;

}
else
{
EPwm3Regs.AQCSFRC.bit.CSFA = 2; // Forcing a continuous Low on output A of EPWM1
EPwm3Regs.AQCSFRC.bit.CSFB = 1;

}
