Is there a moisture sensor to put in the ground?

30 June 2011 - 02:05 AM

Hi, I'd like to take readings of the ground's moisture content. What type of sensor would work best for this application? Does the sensor need to be buried or is there a better way to go about this? Thanks in advance! -blubblub

Serial Interface with 5V?

23 January 2011 - 06:48 PM

Hello,
So I think that I’m a little over my head here. I bought the Sparkfun RGB LED Matrix controller. It requires a 5V power supply which can be provided from the netduino plus but the SPI interface description states that it requires 5V on it CS pin for “high”. The max ouput on the netduino i/o pins is 3.3V right? What’s the best way to interface with this controller? Did I mention I’m a newb :)
Thanks in advance!

Xml Reader

Hello, I'm trying to find a way to read/grab attributes from xml. Is the XmlReader class from the System.Xml namespace available? If not, does an alternative exist?

CLR_E_OUT_OF_MEMORY

18 December 2010 - 10:47 PM

Hello,
I'm trying to load an xml file residing on the SD Card. The original file is 82kb in size and will not load. But if I reduce the file's size to 1kb it works. The error "CLR_E_OUT_OF_MEMORY" occurs when attempting to load the 82kb file. Does a limitation exist that I'm not aware of? Thanks in advance!!! My code below:

using (StreamReader r = new StreamReader("\\SD\\test.xml"))
                {
                    if (r.BaseStream.Length > 0)
                    {
                        do
                        {
                            
                            string line = r.ReadToEnd();
                            Debug.Print(line);
                            r.Close();


                        } while (!r.EndOfStream);
                    }
       
                }
