ArduinoMega2560 und SD-Card Modul bringen mich zur Weissglut... ;)

[oderlachs]

Hallo Freunde !

Bestimmt hat wer von Euch auch schon von diesem Problem gehört, vielleicht selber gehabt und es gelöst. Ich hatte mich im Web glaube ich ausreichend belesen. So habe ich das Modul bei Ebay erstanden

Ageschlossen am Arduino ist es über einen Sparkfun 4Ch-PegelShifter BOB 12009.

Die Pins sind wie folgt beschaltet

SD        Arduino Mega
CS    =  53
SCK   =  52
MOSI  =  51
MISO  =  50

Ich habe zwei Module getestet und auch mehrere SD Karten, aber nur Fehlermeldungen, das die SD Card nicht Initialisiert werden kann...

Hat wer noch nen Tip für mich ??

Ich werde die Module nochmals am Arduino UNO testen, denn da ging es ja ...komisch

Gruss und Danke

Gerhard

Nachtrag :

Arduino UNO

Initializing SD card...Wiring is correct and a card is present.

Card type: SD2

Volume type is FAT16

Volume size (bytes): 1977286656
Volume size (Kbytes): 1930944
Volume size (Mbytes): 1885

Files found on the card (name, date and size in bytes):

ArduinoMega:

Initializing SD card...initialization failed. Things to check:
* is a card is inserted?
* Is your wiring correct?
* did you change the chipSelect pin to match your shield or module?

Hier der geänderte Source von Arduino Beispielen (Cardinfo)

/*
  SD card test 
   
 This example shows how use the utility libraries on which the'
 SD library is based in order to get info about your SD card.
 Very useful for testing a card when you're not sure whether its working or not.
     
 The circuit:
  * SD card attached to SPI bus as follows:
 ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila  51 ArduMega
 ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila  50 ArduMega
 ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila   52 ArduMega
 ** CS - depends on your SD card shield or module.      53 ArduMega
         Pin 4 used here for consistency with other Arduino examples
