since we're just testing if the card is working!
#CHANGE SD CARD SERIAL NUMBER CODE#
we'll use the initialization code from the utility libraries PinMode(10, OUTPUT) // change this to 53 on a mega or the SD library functions will not work. (10 on most Arduino boards, 53 on the Mega) must be left as an output Note that even if it's not used as the CS pin, the hardware SS pin
#CHANGE SD CARD SERIAL NUMBER SERIAL#
Open serial communications and wait for port to open: Adafruit SD shields and modules: pin 10 change this to match your SD shield or module set up variables using the SD utility library functions: ** Pin 4 used here for consistency with other Arduino examples ** CS - depends on your SD card shield or module. ** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila ** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila ** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila * SD card attached to SPI bus as follows: Very useful for testing a card when you're not sure whether its working or not. SD library is based in order to get info about your SD card. This example shows how use the utility libraries on which the' If none of that fixes the problem, try replacing the SD card. If an error occurs, please recheck all the previous steps, and make sure the SD card is working. You can see the follow image after Click the serial monitor. In the case of the SD card normal work, it will print the SD card type.Then print the type and size of the FAT-type volume.įinally, get the files information such as name, date and size in bytes that found on the card. If not, there will output some reasons that may lead to this result. There is a brief description to above code:įirst check if the card is working. There are also many other examples in this library, like “ReadWrite”. You are not sure whether its working or not. 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 Open "CardInfo"example via the path: File → Examples → SD → CardInfo.

When you complete the hardware installation, it should look like this When you use a Micro SD card, please insert Micro SD card into the adopter, and then insert the Micro SD card Adopter into the socket as shown below.

You can stack on other shields that work with the unused pins. Comparing to previous versions, it combines the standart SD slot and the Micro SD slot into a standard one, the included adaptor enables using of Micro SD cards. It will only occupy the SPI port of your Arduino. Users can read/write SD card via Arduino’s built-in SD library. It provides a storage space for your Arduino. This is the newly released SD card V4.0 shield.
