Arduino Micro SD卡模块使用指南
/*
* MOSI - pin 11
** MISO - pin 12
** CLK - pin 13
** CS - pin 4 (for MKRZero SD: SDCARD_SS_PIN)

if (myFile) {
Serial.print("Writing to test.txt...");
myFile.println("testing 1, 2, 3."); // if the file opened okay, write to it:
myFile.close(); // close the file:
Serial.println("done.");
} else {
Serial.println("error opening test.txt"); // if the file didn't open, print an error:
}
myFile = SD.open("test.txt"); // re-open the file for reading:
if (myFile) {
Serial.println("test.txt:");
while (myFile.available()) {
Serial.write(myFile.read()); // read from the file until there's nothing else in it:
}
myFile.close();
} else {
Serial.println("error opening test.txt");
}
}
void loop() {
// nothing happens after setup
}
合着LZ是想锻炼我信息提取和英文水平呢 主要是为了记录一下自己做过的东西
