TMS320F28388D: EPWM触发ADC中断

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

EPWM触发ADC采样中断，是不是同时触发ADCA\B\C\D四个核采样，INT_ADCA1只是一个中断

Interrupt_register(INT_ADCA1, &PWM_Sample_Int_Hook);
EPWM_disableADCTrigger(EPWM1_BASE, EPWM_SOC_A);
EPWM_setADCTriggerSource(EPWM1_BASE, EPWM_SOC_A, EPWM_SOC_TBCTR_U_CMPA);
EPWM_enableADCTrigger(EPWM1_BASE, EPWM_SOC_A);

EPWM_setADCTriggerEventPrescale(EPWM1_BASE, EPWM_SOC_A,p->Sample_ratio);
Interrupt_enable(INT_ADCA1);

    关于此，建议您看一下C2000ware内的例程

    adc_ex11_multiple_soc_epwm 

    C:\ti\c2000\C2000Ware_3_04_00_00\driverlib\f2838x\examples\c28x\adc 

    //! This example sets up ePWM1 to periodically trigger a set of conversions on
    //! ADCA and ADCC. This example demonstrates multiple ADCs working together
    //! to process of a batch of conversions using the available parallelism
    //! accross multiple ADCs.
