Got some LCD shield code working now want to test out the SD…
Yes, it is in the free ebook! Have you looked?
Error 1 ‘GHIElectronics.NETMF.IO.PersistentStorage’ does not contain a definition for 'PersistentStorage_ID_SD"
Directory object doesn’t exist…
Basically a straight copy/paste…
Well I included some more assemblies (System.IO…thought it already was included)…that got the Directory class
MountFileSystem seems to succeed but VolumeInfo.GetVolumes returns empty array…
Still have to PersistentStorage sdPS = new PersistentStorage(“SD”); // Using string
aha! The book is not all updated for NETMF 4.0…we will update it once the new release is out (this week)
Take a look at example under persistent storage class in documentation http://ghielectronics.com/downloads/NETMF/Library%20Documentation/Index.html
Actually I’m looking at that now…
PersistentStorage sdPS = new PersistentStorage(“SD”);
string files = Directory.GetFiles(@ “\SD”)
Still nothing returned…
Maybe it’s the SD cards format…
VolumeInfo.GetFileSystems() returns a single item array "FAT"
SD card was probably formatted on my phone…seem to remember reading FAT32 is only supported format…
Reformatted the uSD to FAT32...VolumeInfo.GetFileSystems still returned single string "FAT"...
Got it working...here is the code
PersistentStorage luSD = new PersistentStorage("SD"); // Get the uSD
luSD.MountFileSystem(); // Mount the file system
// string lfs = VolumeInfo.GetFileSystems(); // Testing
VolumeInfo lVolumes = VolumeInfo.GetVolumes(); // Should get at least one volume
if (lVolumes.Length > 0)
string lRootDirectory = lVolumes.RootDirectory; // Assume SD is first volume
string lFiles = null;
lFiles = Directory.GetFiles(lRootDirectory); // Get list of files
luSD.UnmountFileSystem(); // Unmount uSD
Can now play with displaying files/directories on LCD shield...scrolling with the buttons...
nice! Let us know how it goes
