Need some help with ADC sequencer 0 with 3 analog inputs

Hello everyone,

I'm trying to set up ADC1 sequencer 0 to input from 3 analog channels. I assume this is possible, right?

I set up the sequencer and all the 3 steps, however the interrupts are not being generated.

I paste the setup code bellow:

void ADC_Light_sensor_init(void) //Initialize microphone input
{
SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC1); //The ADC1 peripheral must be enabled for use.
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOE); //Enable GPIO port E

GPIOPinTypeADC(GPIO_PORTE_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3); // Configure PE1, PE2, PE3 as analog input
GPIODirModeSet(GPIO_PORTE_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, GPIO_DIR_MODE_IN); //Set direction input for PE1, PE2, PE3
GPIOPadConfigSet(GPIO_PORTE_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, GPIO_STRENGTH_2MA,GPIO_PIN_TYPE_ANALOG); //Configure PUR for PE3

IntDisable(INT_ADC1SS0);

ADCIntClear(ADC1_BASE, 0); //Clear interrupt flag for ADC1 sequencer 0
ADCIntDisable(ADC1_BASE, 0); //Disable interrupts from ADC1 sequencer 0
ADCSequenceDisable(ADC1_BASE,0); //Disable ADC1 sequencer 0

//All sensor ADC configuration
ADCSequenceConfigure(ADC1_BASE,0, ADC_TRIGGER_PROCESSOR, 1); 
ADCSequenceStepConfigure(ADC1_BASE,0,0, ADC_CTL_CH0); //Configure step 0
ADCSequenceStepConfigure(ADC1_BASE,0,1, ADC_CTL_CH1); //Configure step 1 
ADCSequenceStepConfigure(ADC1_BASE,0,2, ADC_CTL_CH2 | ADC_CTL_IE | ADC_CTL_END); //Configure step 2

ADCSequenceEnable(ADC1_BASE,0); //Enable ADC1 sequencer 0
ADCIntEnable(ADC1_BASE, 0); //Enable interrupts from ADC1 sequencer 0

IntPrioritySet(INT_ADC1SS0,(Int_Prio_Light_Sens)<<5); 
IntEnable(INT_ADC1SS0); //Enable interrupts from ADC1 sequencer 0
}

And here I have the ISR:

void ADC1Seq0_Handler(void)	//ADC0 Seq3 ISR
{
	uint32_t Light;
	if(ADCIntStatus(ADC1_BASE, 0, false))
	{
		ADCIntClear(ADC1_BASE, 0); 	//Clear interrupt flag
		ADCSequenceDataGet(ADC1_BASE, 0, &Light);		
		Mx_LS_Value = (Light&0xFFF);
		Rx_LS_Value = ((Light&0xFFF000)>>12);;
		Lx_LS_Value = ((Light&0xFFF000000)>>24);*/
	}
}

The ADC is triggered by the software every 100ms with ADCProcessorTrigger(ADC1_BASE, 0);

If I eliminate two of the three steps, it works.

Also if I use a different sequencer for different analog input.

However I would like to have all 3 inputs on one sequencer, is this possible?

Thanks & Regards,

Alex
