A FAT File System module:

Yes I know this two links for SPI and FAT File System, but anyway I can´t see any results on my display, for example a picture. Can you or somebody give me an example code to see a Picture on the display from my sd-card? Or someone help me on my Code?

''I can´t see any results on my display''

What? Not any?? But you said before that you see a warning message?!''Or someone help me on my Code?'' It's your code what debugging have you done?

Here are some debugging tips & techniques:

Sry I mean that I see only my warning message on the display, but I cant see a picture, what I have stored bevor on my microSD. So my program debug correctly, but I see only the messages. Could you look at my attechment program!?  Or give me an other idea, where I can see picture on the display...

thank you and regards marc

''my program debug correctly''

No - clearly it doesn't!''Or give me an other idea'' If the program is giving you a message saying that it can't find a picture, then it should be easy to find that message in the source code. It should then be easy to find what things could cause that message to be displayed. Then you'll have a good clue as to what needs fixing...
