아이디 비번

됫다

자 그럼 스타트는 라즈베리파이를 먼져 열고 시작해 보겠습니다.

푸티를 열어주고

잘됫으

아두이노 설치부터 해야됨

끗!!

똭 써주고

뭔가 됫음 근뭔지는 모름 일단 됫음

그리고 파일하나 만들자

미쿡 형이 잘 설명도 써놧음 찬찬 히 읽으면 이해됨

나는 시리얼 보드벤드?? baud??? 이거 115200 이라 

바꿔줫음

그리고 실행!!

아 

이거 아두이누는 

이렇게 넣어주고

#include <DHT.h>
#define DHTTYPE DHT11

int pinGnd = 4;
int pinVcc = 3;
int pinDht = 2;

DHT dht(pinDht, DHTTYPE);

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  pinMode(pinVcc, OUTPUT);
  pinMode(pinGnd, OUTPUT);
  digitalWrite(pinVcc, HIGH);
  digitalWrite(pinGnd, LOW);

  dht.begin();
}

void loop() {
  // put your main code here, to run repeatedly:
  delay(2000);
  float fTemp = dht.readTemperature();
  float fHumi = dht.readHumidity();

  if(isnan(fTemp) || isnan(fHumi)) {
    Serial.println("Falled to read from DNT semsor!");
    return;

  Serial.print("Temperature : ");
  Serial.print(fTemp);
  Serial.print("[C]\t ");
  Serial.print("Humidity: ");
  Serial.print(fHumi);
  Serial.print("%\n");

이거 칩 셋팅은

이렇게 햇음

자그럼 작성도 다됫고

 $ dmesg|tail

아두이노 잘 읽히나 잘보고

$ sudo gcc test.c -o hello -l wiringPi -DRaspberryPi

  $ sudo ./hello

이렇게

잘 만들어주면

습도 보내기 완료!!

좋았스~

일단 FTP 서버를 설치 해야한다

비번 바꾸자

이제 File 넘겨보자

filezilla

https://filezilla-project.org/download.php?type=client

다운하고 

이거 실행해서 라즈베리 연결해준다

와 잘보내짐

편함

이거 압축 명령어 

압축하기 명령어 | 복사 해서 넣기 | 파일이름 | 뭐뭐넣을래 ?
tar cvfz tcp.tar.gz *

명령어  복사  이름  모두

압축됨

통신

우리의 브레인 퍽을 가져왓다

음 보내는게 안됨..

뭐지

다시시작하자

tar xvzf tcp.tar.gz

압축풀기

일단 파일 옴기고

https://www.raspberrypi.org/downloads/

빨리!빨리!!

ssh

찾았다 이놈 

BREACH 욕아닌가?

일단 시작

아디!!!!   pi 

비번!!!!!   raspberry

접속!!!!!!!!

sudo raspi-config

US!!!!! 소리질러!!!

와이파이 다써

비번도쳐

OK!!!!!

됫으

다됫어!!!

아아아아

iwconfig

 cat /etc/wpa_supplicant/wpa_supplicant.conf

ifconfig

써버 잡혓다 !!!!!!

https://webnautes.tistory.com/903

여기까지가

설치

이제 고정아이피

netstat -nr 로 확인부터

2018년 전꺼는 /etc/network/interfaces

2018년 후꺼는 /etc/dhcpcd.conf

static IP

이부분을 변경

음 잘써줫어

혹시 모르니깐 잘 저장해 놓고

sudo /etc/init.d/networking restart

자

됫어요

끗!!!!!!

https://withcoding.com/46

2018년이후는

https://baked-corn.tistory.com/39

IP v4 에 고정 ip를 쓰고

이제 라즈베리 파이는 

192.168.0.140로 해보자

 이제 조립하자

저거 케이쓰끼고 
방열판 만들어야 함
아님안들어감 ㅎㄸ

이제 메모리에
운영체제 저장해야함

컴터로 들어가자

https://www.raspberrypi.org/

여기서 이제 다운로드 해야함

여기로다운로드 하면 된다 

제일 큰거 하면 된다

https://sourceforge.net/projects/win32diskimager/

이제 

디스크를 써줘야 한다

두개가 있으면 된다

설치되면 ssh 를 추가해준다

저거 인터넷 알아서 열어줌

https://putty.ko.softonic.com/

PUTTY 설치하고

통신

주소 다시찾았더니 바껴있었음 그래서 다시 찾음

login as: 여기는 아이디(pi)

pi@192.168.30.148's password: 여기는 비번(raspberry)

저거다 초기 아이디 비밀번호임 

이제 고정 아이피를 만들어보자

뭔가 여러가지 뜬다

sudo raspi-config

일단 와이파이 설정좀 보자

잘따라와라

와이파이 이름

 집에 공유기 이름을 쳐주면 된다

와이파이 비번

집에 비번을 쳐주면 된다

그리곤 피니쉬

다시보니깐 와이파이 포트를 이제 인식한다

wlan0 는 와이파이를 의미한다

뭔가 됫다

설치과정 

두번쩨 메모리에

저장이 되어있고

처음 부트로드(bootloader)가 시작된다

커널띠워주는 역활 

운영체제의 핵심 

커널를 시작하여 

유니프로세스 0 번으로 운영체제를 시작하기함

커널의 메인함수가 시작됨

메모리가져오고 램띠우고 인터넷 열고

운영체게 키고 등등하는 일을한다
