Hallo ich komme mit meinen Adruino Lenoardo nicht weiter.
Problem:
Er erkennt den SD-Kartenleser einfach nicht ich haben ihnen an verschieden Leonardos getestet immer mit dem ergebnis Erkennungs Fehler
Nun habe ich in meiner verzweiflung ihn an einen Uno Angeschlossen gleicher Skech und Siehe da er Läuft wie ein Uhrwerk
Ich also Pin für pin zurück an den Leonarde und wieder Fehler
Als Skech verwenden Ich:
/*
SD card read/write
This example shows how to read and write data to and from an SD card file
The circuit:
SD card attached to SPI bus as follows:
** MOSI - pin 11
** MISO - pin 12
** CLK - pin 13
** CS - pin 4 (for MKRZero SD: SDCARD_SS_PIN)

// so you have to close this one before opening another.
myFile = SD.open("test.txt", FILE_WRITE);
// if the file opened okay, write to it:
if (myFile) {
Serial.print("Writing to test.txt...");
myFile.println("testing 1, 2, 3.");
// close the file:
myFile.close();
Serial.println("done.");
} else {
// if the file didn't open, print an error:

// re-open the file for reading:
