Hi I have recently upgraded to RC5 but I can't get some basic functionality to work.

AnalogInput analogInput1 = new AnalogInput(Cpu.AnalogChannel.ANALOG_0);
    	AnalogInput analogInput2 = new AnalogInput(Cpu.AnalogChannel.ANALOG_0, 8);

I keep getting the following exception.

A first chance exception of type 'System.Net.Sockets.SocketException' occurred in Microsoft.SPOT.Net.dll
A first chance exception of type 'System.ArgumentException' occurred in Microsoft.SPOT.Hardware.dll
An unhandled exception of type 'System.ArgumentException' occurred in Microsoft.SPOT.Hardware.dll

Any ideas?

Also does somebody have an RC5 pwm example? I am not sure of the mapping between the Netduino Pin numbers and the SPOT pins.

For analog inputs I'm using:

static SecretLabs.NETMF.Hardware.AnalogInput accX = new SecretLabs.NETMF.Hardware.AnalogInput(Pins.GPIO_PIN_A1);

Here is something I'm using for changing the background color of an RGB 4x20 LCD display in RC5. Works great. You should be able to extract what you need from the example. (Note, the PWM pins are 5,6,9,10)

    	// LCD RGB LED Constants
    	const Cpu.Pin LCD_LED_RED = Pins.GPIO_PIN_D10;
    	const Cpu.Pin LCD_LED_GREEN = Pins.GPIO_PIN_D6;
    	const Cpu.Pin LCD_LED_BLUE = Pins.GPIO_PIN_D5;

    	// The LCD's RGB LED (True for LCD, False for an RGB LED)
    	public static RGBLed Led = new RGBLed(LCD_LED_RED, LCD_LED_GREEN, LCD_LED_BLUE, true);

	public class RGBLed
	{
    	/// <summary>Reference to the red pin</summary>
    	private PWM _Red;
    	/// <summary>Reference to the green pin</summary>
    	private PWM _Green;
    	/// <summary>Reference to the blue pin</summary>
    	private PWM _Blue;
    	/// <summary>True when it's common anode, false if it's common cathode</summary>
    	private bool _CommonAnode;

    	public RGBLed(Cpu.Pin RedPin, Cpu.Pin GreenPin, Cpu.Pin BluePin, bool CommonAnode = true)
    	{
        	this._Red = new PWM(RedPin);
        	this._Green = new PWM(GreenPin);
        	this._Blue = new PWM(BluePin);
        	this._CommonAnode = CommonAnode;
    	}

	}

HI Dave But I could no longer see the SecretLabs Libraries so I assumed stupidly that they had rolled them into the Spot libraries. I am just installing the latest SDK now. Thanks for putting me on the right track. Yeah, all back up and running, no code changes thankfully.
