Hi,
I have setup an ADC SOC event on the falling edge of PWMB, and I enabled interrupt1, as below:
EALLOW;
AdcRegs.INTSEL1N2.bit.INT1E = 1; /* Enabled ADCINT1 */
AdcRegs.INTSEL1N2.bit.INT1CONT = 0; /* Disable ADCINT1 Continuous mode */
AdcRegs.INTSEL1N2.bit.INT1SEL = 0; /* setup EOC0 to trigger ADCINT1 to fire */
AdcRegs.ADCSOC0CTL.bit.CHSEL = 0x8; /* Set SOC0 channel select to ADCINB0 */
AdcRegs.ADCSOC0CTL.bit.TRIGSEL = ADCTRIG_EPWM1_SOCB; //6; /* Set SOC0 start trigger on EPWM1B, due to round-robin SOC0 converts first then SOC1 */
AdcRegs.ADCSOC0CTL.bit.ACQPS = 6; /* Set SOC0 S/H Window to 7 ADC Clock Cycles, (6 ACQPS plus 1) */
AdcRegs.ADCCTL1.bit.INTPULSEPOS = 0; /* Configure early interrupts */
EDIS;
Can I start more than one conversion using ADCINT1 and PWMB, for example by adding this configuration?
EALLOW;
AdcRegs.INTSEL1N2.bit.INT1E = 1; /* Enabled ADCINT1 */
AdcRegs.INTSEL1N2.bit.INT1CONT = 0; /* Disable ADCINT1 Continuous mode */
AdcRegs.INTSEL1N2.bit.INT1SEL = 1; /* setup EOC1 to trigger ADCINT1 to fire */
AdcRegs.ADCSOC1CTL.bit.CHSEL = 0xA; /* Set SOC1 channel select to ADCINB2 */
AdcRegs.ADCSOC1CTL.bit.TRIGSEL = ADCTRIG_EPWM1_SOCB;
AdcRegs.ADCSOC1CTL.bit.ACQPS = 6; /* Set SOC1 S/H Window to 7 ADC Clock Cycles, (6 ACQPS plus 1) */
AdcRegs.ADCCTL1.bit.INTPULSEPOS = 0; /* Configure early interrupts */
EDIS;
