Arduino 보드 간의 유선 직렬 통신 설정

이 블로그는 두 개의 Arduino 보드 간에 유선 직렬 통신을 설정하는 방법을 설명합니다.

This tutorial is meant for those with some knowledge of Arduino and IoT.
The purpose of building this blog is to write down the detailed operation history and my memo for learning the Arduino.
If you are also interested and want to get hands dirty, just follow these steps below and have fun!~

마스터 보드용 코드(Arduino 101):

Send integer data to slave board

void setup() {
  // Begin the Serial at 9600 Baud
  Serial.begin(9600);
  Serial1.begin(9600);
}

int thisByte = 33;

void loop() {
  Serial1.write(thisByte); //Write the serial data
  if (thisByte == 126) {    // you could also use if (thisByte == '~') {
     //This loop loops forever and does nothing
     // holds
    while (true) {
      continue;
    }
    //thisByte = 32;
  }
  // go on to the next character
  thisByte ++;
  //delay(1000);
}

Receive data from the master board, and print the data to console

int incomingByte = 0;  

void setup() {
  // Begin the Serial at 9600 Baud
  Serial1.begin(9600);
  Serial.begin(9600);
}
void loop() {
  // send data only when you receive data:
  if (Serial1.available() > 0) {
  // read the incoming byte:
     incomingByte = Serial1.read();
     // say what you got:
     Serial.print("Received:  ");
     Serial.write(incomingByte);
     Serial.print("    DEC:  ");
     Serial.print(incomingByte, DEC);
     Serial.print("    HEX:  ");
     Serial.print(incomingByte, HEX);
     Serial.print("    OCT:  ");
     Serial.print(incomingByte, OCT);
     Serial.print("    BIN:  ");
     Serial.print(incomingByte, BIN);
     Serial.println(" ");
   }
}
