Dear team:
I used two methods to update the CMPA value in CLA, but none succeeded:
Method 1：
interrupt void Cla1Task1 (void)
{
//Local Variables
//i=fGridVoltRatio;
//Code
__mdebugstop();
//int i;
Num = 100.0;
Den = 10.0;
//i++;
GpioDataRegs.GPATOGGLE.bit.GPIO20 = 1;
__meallow();
EPwm12Regs.CMPB.bit.CMPB = 10;
EPwm1Regs.CMPA.bit.CMPA = 100;
__medis();
//
/*if(EPwm1Regs.CMPA.bit.CMPA >= 400)
{
EPwm1Regs.CMPA.bit.CMPA--;
}
if(EPwm1Regs.CMPA.bit.CMPA <= 40)
{
EPwm1Regs.CMPA.bit.CMPA++;
}*/
// Res = CLAdiv(Num,Den);
Res = Num/Den;
}It can be sure that the program has entered the CLA task, because the GPIO20 has been inverted and the RES value has been calculated. But when single step debugging, register“ EPwm1Regs.CMPA.bit.CMPA ”The value in is always the value I initialized, not 100
Method 2:
interrupt void Cla1Task1 (void)
{
//Local Variables
//i=fGridVoltRatio;
//Code
__mdebugstop();
//int i;
Num = 100.0;
Den = 10.0;
//i++;
GpioDataRegs.GPATOGGLE.bit.GPIO20 = 1;
__meallow();
EPwm12Regs.CMPB.bit.CMPB = 10;
EPwm1Regs.CMPA.bit.CMPA = Num;
__medis();
//
/*if(EPwm1Regs.CMPA.bit.CMPA >= 400)
{
EPwm1Regs.CMPA.bit.CMPA--;
}
if(EPwm1Regs.CMPA.bit.CMPA <= 40)
{
EPwm1Regs.CMPA.bit.CMPA++;
}*/
// Res = CLAdiv(Num,Den);
Res = Num/Den;
}I use Num to assign a value to EPwm1Regs.CMPA.bit.CMPA. when single step debugging, Num becomes 10.0 , but the value of EPwm1Regs.CMPA.bit.CMPA has not changed. It's still the value of my initialization.
Is there anything else I need to pay attention to when I update the value of CMPA register in CLA?
Best regards
