MSP432E401Y: Reading analog output from INA210 with MSP432E401Y

Hi,

  Below is an example for configuring AIN7. 

    //
    // The ADC0 peripheral must be enabled for use.
    //
    SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC0);

    //
    // For this example ADC0 is used with AIN7 on port D4.
    // The actual port and pins used may be different on your part, consult
    // the data sheet for more information.  GPIO port D needs to be enabled
    // so these pins can be used.
    // TODO: change this to whichever GPIO port you are using.
    //
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOD);

    //
    // Select the analog ADC function for these pins.
    // Consult the data sheet to see which functions are allocated per pin.
    // TODO: change this to select the port/pin you are using.
    //
    GPIOPinTypeADC(GPIO_PORTD_BASE, GPIO_PIN_4);

    //
    // Enable sample sequence 3 with a processor signal trigger.  Sequence 3
    // will do a single sample when the processor sends a signal to start the
    // conversion.  Each ADC module has 4 programmable sequences, sequence 0
    // to sequence 3.  This example is arbitrarily using sequence 3.
    //
    ADCSequenceConfigure(ADC0_BASE, 3, ADC_TRIGGER_PROCESSOR, 0);

    //
    // Configure step 0 on sequence 1.  Sample channel 8 (ADC_CTL_CH8) in
    // single-ended mode (default) and configure the interrupt flag
    // (ADC_CTL_IE) to be set when the sample is done.  Tell the ADC logic
    // that this is the last conversion on sequence 1 (ADC_CTL_END).  Sequence
    // 3 has only one programmable step.  Sequence 1 and 2 have 4 steps, and
    // sequence 0 has 8 programmable steps.  Since we are only doing a single
    // conversion using sequence 1 we will only configure step 0.  For more
    // information on the ADC sequences and steps, reference the datasheet.
    //
    ADCSequenceStepConfigure(ADC0_BASE, 1, 0, ADC_CTL_CH7 | ADC_CTL_IE |
                             ADC_CTL_END);

    //
    // Since sample sequence 1 is now configured, it must be enabled.
    //
    ADCSequenceEnable(ADC0_BASE, 1);

    //
    // Clear the interrupt status flag.  This is done to make sure the
    // interrupt flag is cleared before we sample.
    //
    ADCIntClear(ADC0_BASE, 1);
