Hi all,
I’m a new programmer on netmf but not new on .net. I want t thanks GHI innovation. The gadgeteer’s and ghi mainboard with their modules are a good issue for my developpement time.
on a project, I want to log informations on µSD. And this doesn’t work. I searched since days for a solution, in the forum and codeshare but no one samples work.
My sdcard is a kingston 4GB SDHC. Format in FAT32 / 4k per blocks.
The code :
using System;
using System.IO;
using Microsoft.SPOT;
using Microsoft.SPOT.IO;
using GT = Gadgeteer;
using GTM = Gadgeteer.Modules;
using Gadgeteer.Modules.GHIElectronics;
namespace GadgeteerApp1
{
public partial class Program
{
private static string szTextContent = "If I told you, I'd have to kill you...\r\n";
void ProgramStarted()
{
DebugPrint("Program Started");
sdCard.DebugPrintEnabled = true;
sdCard.SDCardMounted += new GTM.GHIElectronics.SDCard.SDCardMountedEventHandler(sdCard_SDCardMounted);

Microsoft.SPOT.IO.RemovableMedia.Insert += new Microsoft.SPOT.IO.InsertEventHandler(RemovableMedia_Insert);
}
void RemovableMedia_Insert(object sender, Microsoft.SPOT.IO.MediaEventArgs e)
{
DebugPrint("Insert - Mounted : " + e.Volume.Name);
}

}

}

}
and result in debug output
