SD card test does not work .

Post by FROMJAPAN »

Thank you for your help .

Using the Adafruit Data Logger Shield and Arduino Leonardo, SD card test does not work .

SD card is not within
. 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?

It is , but has no reaction SD Card is entered .
It does not respond when you press the spacebar or Enter key .

SD holder of the library has been interchanged. // We'll use the initialization code from the utility libraries of sketch
// Since we're just testing if the card is working!
while (! card.init (SPI_HALF_SPEED, 10, 11, 12, 13)) {
I have also changed .
https://learn.adafruit.com/adafruit-dat ... d-leonardo

I also tried the SD card several species .
I have also confirmed format .

What is wrong

I will paste the sketch .

/*
  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:
 ** UNO:  MOSI - pin 11, MISO - pin 12, CLK - pin 13, CS - pin 4 (CS pin can be changed)
  and pin #10 (SS) must be an output
 ** Mega:  MOSI - pin 51, MISO - pin 50, CLK - pin 52, CS - pin 4 (CS pin can be changed)
  and pin #52 (SS) must be an output
 ** Leonardo: Connect to hardware SPI via the ICSP header
 		Pin 4 used here for consistency with other Arduino examples

Has been resolved .

Was operating normally as you open the serial monitor after you reboot after writing the sketch of Leonardo.
Thank you
