겨울철 원격 시동시 OFF로 초기화 되는 순정 열선 모듈, 메모리 모듈로 따듯하게.

#include <IRremote.h>

int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;

void setup() {
  Serial.begin(9600);

FFFFFFFF 출력으로 문제된 대부분의 사람들이 위와 같은 예제 소스코드로 테스트를 했을 것이다.

그리고 IR 수신회로를 구성하여 리모컨을 눌렀을 때 위와 같이 FFFFFFFF의 데이터만 수신 했을것이다.

#include <IRremote.h>

int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);

void setup() {
  Serial.begin(9600);
  irrecv.enableIRIn();
}

void loop() {
  if (irrecv.decode()) {
    Serial.println(irrecv.decodedIRData.decodedRawData, HEX);
    irrecv.resume();
  }
}

소스코드를 위와 같이 수정하여 업로드 해보자

값이 제대로 출력되는 것을 확인할 수 있다.

수신된 데이터를 식별할 수 없는 상태에서 decode 함수에 인자 값이 전달되면 FFFFFFFF를 반환 하게된다. 이를 해결하기 위해 원시 데이터를 직접 출력하여 해결할 수 있다.

/* 
  A servo is activated by creating an instance of the Servo class passing 
  the desired pin to the attach() method.
  The servos are pulsed in the background using the value most recently 
  written using the write() method.

  Note that analogWrite of PWM on pins associated with the timer are 
  disabled when the first servo is attached.
  Timers are seized as needed in groups of 12 servos - 24 servos use two 
  timers, 48 servos will use four.
  The sequence used to seize timers is defined in timers.h

  The methods are:

    Servo - Class for manipulating servo motors connected to Arduino pins.

    attach(pin )  - Attaches a servo motor to an I/O pin.
    attach(pin, min, max  ) - Attaches to a pin setting min and max values in microseconds
    default min is 544, max is 2400  
 
    write()     - Sets the servo angle in degrees.  (invalid angle that is valid as pulse in microseconds is treated as microseconds)
    writeMicroseconds() - Sets the servo pulse width in microseconds 
    read()      - Gets the last written servo pulse width as an angle between 0 and 180. 
    readMicroseconds()   - Gets the last written servo pulse width in microseconds. (was read_us() in first release)
    attached()  - Returns true if there is a servo attached. 
    detach()    - Stops an attached servos from pulsing its I/O pin.

정말 최소한의 기본 설정 후 기본 소스에 컴파일 후 업로드를 했는데 에러가 뜬다.

컴퓨터는 잘못이 없다. 설정을 잘못한 다 내 잘못 ㅠ

프로세서를 ATmega328P (Old Bootloader)로 바꾸면 된다.(프로그래머는 건들지 않아도 됨)

그래도 최근에 구입한 보드인데.. 나노가 전부 전 버전 부트로더인가?

업로드 성공~~
