Dears,
COPMB is configured as shadow mode, updating by downflow and peroid. SOCB trigger ADCA ADCB ADCC in increment mode.SOCA trigger ADCA ADCB ADCC in decrement mode. The value and triggering mode of COMPB are changed in the PWM interruption by peroid and downflow.
ADDC is working, but ADCA and ADCB is not working? below is my code.
// Disable SOCA
EPWM_disableADCTrigger(EPWM1_BASE, EPWM_SOC_A);
EPWM_setADCTriggerSource(EPWM1_BASE,EPWM_SOC_A,EPWM_SOC_TBCTR_D_CMPB);
EPWM_setADCTriggerEventPrescale(EPWM1_BASE,EPWM_SOC_A,1);
EPWM_enableADCTrigger(EPWM1_BASE,EPWM_SOC_A);
// Disable SOCB
EPWM_disableADCTrigger(EPWM1_BASE, EPWM_SOC_B);
EPWM_setADCTriggerSource(EPWM1_BASE,EPWM_SOC_B,EPWM_SOC_TBCTR_U_CMPB);
EPWM_setADCTriggerEventPrescale(EPWM1_BASE,EPWM_SOC_B,1);
EPWM_enableADCTrigger(EPWM1_BASE,EPWM_SOC_B);
