Chris,

Excuse me for this late reaction. No time this week.
This nigth I wake up with a possible solution. I just forget the 2 pullup resistors on the SDCL en SDA pin. I tried it with a 24lc256 EEPROM to test the I2C bus. With 2 pullups its works and also the I2C clock.
Thanks again,
Henk.

Hi hendrikdutje,

The DateTime constructor exception in the netduinohelpers library looks like it is caused by invalid input. Can you step into the code and find the exact line which throws the exception?

Chris

Nice such a forum to solve your own problems........

I solved the problem with the SD card.....

I updated the firmware and connected pin D8 with a single cable to Pin D10.
I format my sandisk micro sdcard to fat16 (standard format in windows 7) and I used the next code...

Debug and get....

The thread '<No Name>' (0x2) has exited with code 0 (0x0).
directory count: 1
directory: \SD1
file count: 2
filename: \SD1\hallo.txt
contents: first time...
filename: \SD1\Test.txt
contents: Regel 1
regel 2
regel 3
The thread '<No Name>' (0x1) has exited with code 0 (0x0).
Done.
Waiting for debug commands...
The program '[24] Micro Framework application: Managed' has exited with code 0 (0x0).

byte[] data = Encoding.UTF8.GetBytes("first time...");

Filehandle.Write(data, 0, data.Length);
Filehandle.Close();
Thread.Sleep(1000);

string[] directories = System.IO.Directory.GetDirectories(@"\");

Debug.Print("directory count: " + directories.Length.ToString());


for (int i = 0; i < directories.Length; i++)
{
Debug.Print("directory: " + directories[i]);
}

string[] files = System.IO.Directory.GetFiles(@"\SD1");
Debug.Print("file count: " + files.Length.ToString());

{
Debug.Print("filename: " + files[i]);
FileStream fs = new FileStream(files[i], FileMode.Open, FileAccess.Read, FileShare.None, 512);
StreamReader sr = new StreamReader(fs);
Debug.Print("contents: " + sr.ReadToEnd());
}
StorageDevice.Unmount("SD1");


}

}
}

I go further to solve the problm with the ds1307 . Firt testing the IC2 with a I2C EEPROM 24LC256.

I have updated the firmware to the last version :
When I use MFdeploy then I get the next information.....

I tried to debug the ds1307 project of netduinohelpers on a Sparkfun micro SDshield where I have made an Maxim ds1307 clock chip on it with a 32678 oscillator and a 3.3v backup battery. De clock runs on 3.3.V.
When I run it on a Arduino Uno it works.
When I debug the solution in Visual Studio 2010 professional edition I get the next error.

Whe I tried the sd card exactly with the sample on this forum http://forums.netdui...sd-card-sample/
then get the nex error. I use exact the same hardware.

Chris,

Thanks for your quick response.
I try first to update the firmware from my netduino to resolve the problem with the DS1307 e.v.
I disconnected my USB cable and I run my application with a extern 12v adapter en the not used analog pins connected to ground.
It is then much better and stabilized.
Thanks again.

Hi hendrikdutje,

To use an SD card, you need to be running the latest v4.1.1 alpha firmware. Also, what size is your SD card--and is the SD shield 3.3V compatible?

On the analog inputs, if you can post a diagram of what you're doing perhaps we can help diagnose. Also, the ADC on the Netduino is a full 10-bit ADC, so if you reduce your range to 8-bit using AnalogInput.SetRange(0, 255), you might get more traditional 8-bit results.

Chris

When I try to debug a program to read a ds1307 clock or a sd card I always get an error like CLR_E_NOT_SUPPORTED . I am using the examples from netduinohelpers. Also I try to read a lm335 temperature sensor on a analog port. Fluctuating value's are the result. So I am not impressed about the netduino. I Have experience with the arduino and I had no probem to read analog value's , micro-sd card e.v Somebody a solution for the ds1307 and sd-card? sd-card shield is a shield from sparkfun.
