在INTERRUPT.C文件里面
void fast_interrupt(void) { volatile int32 temp;
fir_index = CimRegs.FIQIVEC.all;
if(fir_index == 28) //index =27
{ vloop_filter = (signed int) (Filter0Regs.FILTERYNREAD.bit.YN);
iloop_filter = (signed int) (Filter1Regs.FILTERYNREAD.bit.YN);
if (iloop_filter > vloop_filter)
{ FeCtrl1Regs.EADCDAC.bit.DAC_VALUE = (pmbus_dcdc_config_translated[0].cpcc_imax +350);
LoopMuxRegs.EXTDACCTRL.bit.DAC2_SEL = 4; //voltage loop
LoopMuxRegs.PCMCTRL.bit.PCM_FILTER_SEL =0; //select filter0 for voltage loop slope source
Filter0Regs.FILTERCTRL.bit.KI_STALL =0;
vv_flag =1; if(cc_flag ==1)
{ cv_trans_flag =1;
cc_flag =0;
start_state = START_UP; }
}
里面 FeCtrl1Regs.EADCDAC.bit.DAC_VALUE = (pmbus_dcdc_config_translated[0].cpcc_imax +350);
这里选择的是恒压控制，为什么DAC_VALUE用的是cpcc_imax ，我理解的是电压环应该用的是电压值，而且还+350，请指教，谢谢
