Hi experts,
I'm using 280039C to realize CRM Boost control.
The CMPSS signal has been setup and send to EPWMXbar. Then i setup Digital Compare as this using DCBECT1.sync to reset counter of EPWM4.
But can't reset TBCTR at CMPSS high.
The code is as following:
CMPSS setup:
CMPSS_enableModule(base1);
CMPSS_configDAC(base1,CMPSS_DACVAL_SYSCLK | CMPSS_DACREF_VDDA | CMPSS_DACSRC_SHDW);
CMPSS_setDACValueHigh(base1,2048 +(int16_t)((float32_t)current_limit*(float32_t)2048.0/(float32_t)current_max_sense));
CMPSS_setDACValueLow(base1,2048 -(int16_t)((float32_t)current_limit *(float32_t)2048.0 /(float32_t)current_max_sense));
CMPSS_configHighComparator(base1, CMPSS_INSRC_DAC );
CMPSS_configLowComparator(base1, CMPSS_INSRC_DAC | CMPSS_INV_INVERTED);
CMPSS_configFilterHigh(base1, 2, 10, 7);
CMPSS_configFilterLow(base1, 2, 10, 7);
CMPSS_initFilterHigh(base1);
CMPSS_configOutputsHigh(base1, CMPSS_TRIPOUT_ASYNC_COMP | CMPSS_TRIP_FILTER);
CMPSS_configOutputsLow(base1, CMPSS_TRIPOUT_ASYNC_COMP | CMPSS_TRIP_FILTER);
CMPSS_clearFilterLatchHigh(base1);
CMPSS_clearFilterLatchLow(base1);
