Guten Tag,
ich habe eben das XD-204 XD-05 Data Logger Shield Arduino Uno Erweiterung SD Karte RTC Real Time Clock ausprobiert und leider funktioniert keine der microSD Karten (mit SD Karten Adapter) die ich besitze mit meinem Arduino UNO.
Habe mich eigentlich strikt an die Anleitung gehalten:
- Format the SD card using FAT16/FAT32 files system using SD Formatter to prevent issues
- Insert your SD card into the SD card slot
- Mount the Keyes Data logging shield into your Arduino
- Download SD library and extract it to library folder in your Arduino directory
- Open Cardinfo sketch "SD > CardInfo"
- Change this line const int chipSelect = 4; to const int chipSelect = 10;
Dann kommt der Fehler
Initializing SD card...initialization failed. Things to check:
* is a card inserted?
* is your wiring correct?
* did you change the chipSelect pin to match your shield or module?
im seriellen Monitor. Ich habe es mit 4 verschiedenen Karten, alle FAT16 bzw FAT32 mit dem verlinkten SD formatter Tool (Downloads | SD Association) formatiert, immer mit ChipPin 10, aber auch mal mit 4 und 8 probiert (SD Karten von 32 MB bis 4 GB).
Es ist eine 3V Batterie eingelegt und das RTC Modul funktioniert auch. Ich habe den Shield direkt auf meinen Arduino UNO gesteckt, also kann es auch nicht an der Verkabelung oder Lötstellen liegen.
Ansonsten ist auch überhaupt nichts anderes angeschlossen an beide Boards. Nur eben der Arduino per USB an meinen PC.
Code:
/*
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
** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
** CS - depends on your SD card shield or module.
Pin 4 used here for consistency with other Arduino examples
