    TLE9879 Evaluation Kit

    Hi,
    I am trying to read ADC1 port P2.4. I went to IFXConfigWizard and select Sequence 1 - 6 and select channel 4 (P2.4). If want want to read the ADC only when require how do I do that. Currently I am able to read from the interrupt when I enable Interrupt Channel 4 (P2.4) like the example with Function name called Poti_Handler.
    If I use the interrupt enable when I run the motor the motor not able to run properly. Is there any other around this. I do not need to read ADC while I am running the motor.

    Thank you,
    Eugene

    Finally I managed to get the ADC working. Below is the code I used

    value_valid = ADC1_GetChResult_mV(&mV, ADC1_CH4);

    if (value_valid == true)
    {
    _ADC1 = mV;
    }

    if (_ADC1 > 3000)
    {
    PORT_ChangePin(LED7, PORT_ACTION_SET);
    }
    else
    {
    PORT_ChangePin(LED7, PORT_ACTION_CLEAR);
    }

    I configured all the sequencer 1 to Sequencer 6 with Channel 4(P2.4) check. After compiled I am able to read the ADC P2.4.

    Do I need to configure sequencer 1 to Sequencer 6 for P2.4?
