I might have to get one now that you've done all the hard work

LOL I ordered mine yesterday!

Is this evidence of the "issue" - or is it just a precision issue with the Saleae Logic Probe? Notice the highlighted gaps, which are regularly repeating.

I used this code:

namespace TightLoopTest1
{
    public class Program
    {
        public static void Main()
        {
            OutputPort d2 = new OutputPort(Pins.GPIO_PIN_D2, false);
            bool status = false;
            while (true)
            {
                status = !status;
                d2.Write(status);
            }


        }

    }
}

and got this @ 24Mhz:

3. (**WARNING.. no turning back after this point.) Using a jumper, Connect the 3V3 power header to the ERASE pin (gold pad directly underneath digital pin 0) for about 2-3 seconds. After doing this, disconnect the Netduino from your PC.

...

5. Run SAM-BA. Select the COM port that your device is connected to. In my case this was COM4. Select AT91SAM7X512-ex from the dropdown.

In case it's helpful:

for step 3, here's a pic of the erase pad on my netduino plus:

and for step 5, did not have AT91SAM7X512-ex, but a -ek, so I picked that and it seemed to work fine.

ok i think I got this right -- i believe the right most pin is the - and the center pin is the +:



Is that about what you're doing, with the multimeter/analog input hooked up after the resistor?

I'm sorry, I don't know. According to this picture:



If your room is 72 degrees F, which is 295 degrees K, you should have a reading of about 2.95V, I think.

When you're measuring with the multimeter, is the netduino involved in the circuit at all? I would start with the netduino out of the picture entirely a focus on getting the right readings on a multimeter, then focus on getting them well below 3.3V to be safe for the analog inputs.
