Arduino Function: FileIO.read

Description

file.write(buf, len)

Parameters

  • file: an instance of the File class (returned by FileIO.open())
  • data: the byte, char, or string (char *) to write
  • buf: an array of characters or bytes
  • len: the number of elements in buf

Returns

 byte : write() will return the number of bytes written, though reading that number is optional
