Hi

I have problem creating an AnalogInput on the Shieldbase...

using AnalogInput = SecretLabs.NETMF.Hardware.AnalogInput;
namespace MyNamespace
{
    public class MyClass : MyBaseClass
    {
        private AnalogInput input;

        public MyClass(NetduinoGo.ShieldBase shieldbase)
            : base(shieldbase)
        {
            this.input = new AnalogInput(this.shieldbase.Pins.GPIO_PIN_A0);
        }

The abowe throws ArgumentException. The code is exceuted immediately after another instace of "MyClass" is created with digital pins. The Pin has value 1014.

Running Netduino Go firmware 4.0.0.2.

Thanks in adavance

You can only grab hold of a pin once. So the second instance of MyClass will fail as the first instance is still referencing A0.

Hi Mark

Thanks, but it's not.. I've simplified the code by removing parameters and replaced pin variable with actual value.

Hi Nicky, Are you okay with switching to the new NETMF AnalogInput class? Then instead of the shieldBase.Pins enumeration, you can use the shieldBase.AnalogChannels enumeration.

Hi Nicky,

Nice! Works like a charm!

I actually tried using it, and deleted the using AnalogInput in the top, but apparently VS didn't change the reference. using AnalogInput = Microsoft.SPOT.Hardware.AnalogInput did the magic.
