SoftwareSerial: print(data)

描述

透过软体序列介面传送资料。运作方式与 Serial.print() 相同。

参数

详情请看 Serial.print()

回传

byte：print() 会回传传送资料的位元组数量

范例

SoftwareSerial serial(10,11);
int analogValue;

void setup()
{
  serial.begin(9600);
}

void loop()
{
  // 读取类比脚位 0 的值
  analogValue = analogRead(A0);

  // 以不同的格式送出
  serial.print(analogValue);         // print as an ASCII-encoded decimal
  serial.print("\t");                // print a tab character
  serial.print(analogValue, DEC);    // print as an ASCII-encoded decimal
  serial.print("\t");                // print a tab character
  serial.print(analogValue, HEX);    // print as an ASCII-encoded hexadecimal
  serial.print("\t");                // print a tab character
  serial.print(analogValue, OCT);    // print as an ASCII-encoded octal
  serial.print("\t");                // print a tab character
  serial.print(analogValue, BIN);    // print as an ASCII-encoded binary
  serial.print("\t");                // print a tab character
  serial.print(analogValue/4, BYTE); // print as a raw byte value (divide the
                                     // value by 4 because analogRead() returns numbers
                                     // from 0 to 1023, but a byte can only hold values
                                     // up to 255)
  serial.print("\t");                // print a tab character    
  serial.println();                  // print a linefeed character

  // 在每次读取资料间延迟 10 毫秒
  delay(10);
}
