创建一个文件,然后通过创建一个例子`File@ class, 和调用FileSystem.open()(暗示你想创建程序的地方),来打开它。在"/tmp"(驻留在RAM,来保存闪存读/写电路的有限制的数值)保存程序。 void uploadScript() { File script = FileSystem.open("/tmp/wlan-stats.sh", FILE_WRITE); [Get Code] 用File.print(...
note that only one file can be open at a time, // 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("testi...
;myFile = SD.open(test.txt, FILE_WRITE);if (myFile) Serial.print(Writing to test.txt.); myFile.println(testing 1, 2, 3.); myFile.close(); Serial.println(done.); else Serial.println(error opening test.txt);myFile = SD.open(test.txt);if (myFile) Serial.println(test.txt:); ...
