第一种方法 - 无视注释,直接用2560的SPI引脚对SD卡进行读写操作,2560 对应SPI引脚如下 #define PIN_SPI_SS (53) #define PIN_SPI_MOSI (51) #define PIN_SPI_MISO (50) #define PIN_SPI_SCK (52) 1. 2. 3. 4. 程序运行得到的结果是Initializing SD card...initialization failed!!! 第二种方法 ...
Arduino代码 – 使用CardInfo测试SD卡模块 与SD卡通信是一项繁重的工作，但对我们来说幸运的是，Arduino...
Serial.println(“SD card is ready to use.”); } else { Serial.println(“SD card initialization failed”); return; } 接下来我们打印“日期”,“时间”和“温度” “在串口显示器上。然后我们打开SD卡文件并在那里打印相同的东西。如果我们命名的文件不在那里,它将在那里创建。 在那里打印后,我们关闭SD...
// SD Card Initialization if (SD.begin()) { Serial.println("SD card is ready to use."); } else { Serial.println("SD card initialization failed"); return; } // Create/Open file myFile = SD.open("test.txt", FILE_WRITE); // if the file opened okay, write to it: if (myFile...
Serial.println("SD card initialization failed");return;} // Create/Open file myFile = SD.open(...
再把下面的代码传入arduino控制板,看看效果#include File myFile;void setup()Serial.begin(9600);Serial.print(Initializing SD card.); pinMod 13、e(10, OUTPUT); if (!SD.begin(4) Serial.println(initialization failed!); return;Serial.println(initialization done.);myFile = SD.open(test.txt, FILE...
#include <SD.h> File myFile; void setup() { Serial.begin(9600); while (!Serial) { ; } Serial.print("Initializing SD card..."); if (!SD.begin(10)) { Serial.println("initialization failed!"); return; } Serial.println("initialization done."); ...
Serial.println("SD card initialization failed"); return; } /// } voidloop() { /// sensorValue = analogRead(sensorPin);//Monitoring battery voltage floatvoltage = sensorValue*(5.0/1023.0); lcd.setCursor(0,3);//0,3 lcd.print("Voltage bat: "); lcd...
Serial.print("Initializing SD card..."); if (!SD.begin(4)) { Serial.println("initialization failed!"); while (1); } Serial.println("initialization done."); // open the file. note that only one file can be open at a time, ...
Serial.print("Initializing SD card..."); if (!SD.begin(4)) { Serial.println("initialization failed!"); return; } Serial.println("initialization done."); // open the file. note that only one file can be open at a time, // so you have to close this one before opening another. ...
