meetAndroid修改問題?

dark-man

之前照著範例Multicolor Lamp tutorial做
Multicolor Lamp tutorial的控制端是用拉條控制LED亮度
#include <MeetAndroid.h>

MeetAndroid meetAndroid;


int redled = 9;   
int greenled = 10;
int yellowled = 11;

void setup()  
{
  Serial.begin(57600);
  

  meetAndroid.registerFunction(redled, 'r');
  meetAndroid.registerFunction(greenled, 'g');  
  meetAndroid.registerFunction(yellowled, 'y');


  pinMode(redled, OUTPUT);
  pinMode(greenled, OUTPUT);
  pinMode(yellowled, OUTPUT);
  

  digitalWrite(redled, HIGH);
  digitalWrite(greenled, HIGH);
  digitalWrite(yellowled, HIGH);

}

void loop()
{
  meetAndroid.receive();
}
void red(byte flag, byte numOfValues)
{
  analogWrite(redLed, meetAndroid.getInt());
}
void green(byte flag, byte numOfValues)
{
  analogWrite(greenLed, meetAndroid.getInt());
}
void blue(byte flag, byte numOfValues)
{
  analogWrite(blueLed, meetAndroid.getInt());
}

其中對以下這段的函數不是很懂
void red(byte flag, byte numOfValues)<-不是很懂它的宣告函數
{
  analogWrite(redLed, meetAndroid.getInt());

請懂這部份得大大 幫忙求解 !!
