我有一个带有4个盆的Arduino.另一个Arduino通过i2c接收这4个值并将它们打印在显示器上.问题是我不知道如何发送奴隶所知道的4个值,知道哪个值属于哪个Pot.

奴隶代码:

#include <Wire.h>
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup()
{
  Wire.begin(5);
  Wire.onReceive(receiveEvent);
  Serial.begin(9600);
  lcd.begin(16,2);

}

void loop()
{
}


void receiveEvent(int)
{

 while(Wire.available())
  {
           //How to create this part? How does the Slave know wich value belongs to which pot?
  }

}

主码:

#include <Wire.h>

void setup()

{
  Serial.begin(9600);
  Wire.begin();
  delay(2000);
}

void loop()
{
  int sensor1 = analogRead(A1);
  Wire.beginTransmission(5);
  Wire.write(sensor1);
  Serial.print(sensor1);
  Wire.endTransmission();
  delay(100);

  int sensor2 = analogRead(A2);
  Wire.beginTransmission(5);
  Wire.write(sensor2);
  Serial.print(sensor2);
  Wire.endTransmission();

  delay(500);


}
