IoT 뱃지 만져보기 (마이크로 파이썬 프로그래밍 GPIO & SPI (LCD, 버튼, LED))

 

환경 구성

• IoT Badge USB Driver 설치
• IoT Badge 연결 터미널 S/W 설치
• Network 연결
• Web REPL download 및 연결
• Web REPL로 연결 후 Python File 업로드
• Web REPL에서 execfile 명령으로 Python Code 실행

 

센서 연결하기 (I2C, PWM & ADC (피에조 부저, 조도 센서, 자이로 센서))

 

피에조 부저 동작 맛보기

Node-RED + IoT (Watson IoT 서비스 연동하기!)

 

IBM IoT Platform 구성

1. IBM Cloud의 서비스 카탈로그에서 스타터 킷 중 Internet of things platform starter로 선택

• 바로가기 : https://console.bluemix.net/catalog/starters/internet-of-things-platform-starter

1. Cloud Foundry App 생성

• IoT Platform Starter는 다음과 같이 구성
  • Node.js Runtime 및 Node-RED IoT 서버 애플리케이션
  • Node Flow 데이터 저장을 위한 Cloudant NoSQL Database
  • IoT 플랫폼인 Internet of Things Platform
• 애플리케이션 이름을 영문으로 입력
• 애플리케이션 이름에 따라 자동으로 hostname이 제시되지만 고유한 이름이 되도록 iot201812-{userid}로 변경한다. (예, iot2018-hongjs) 참고. 만약 중복되어도 애플리케이션은 생성되지만 생성한 앱으로 라우팅이 되지 않음

 

Node-RED 실행

1. IoT 서버 애플리케이션 (Node-RED) 접속

iot2018-hongjs 인 경우 Application URL은 다음과 같음

https://iot2018-hongjs.mybluemix.net/red

• 최초 접속 시 관리자 id 및 비밀번호 생성
• 이후 Node-RED에 접속 시 앞서 생성한 관리자 id 및 비밀번호 입력으로 로그인

1. Node-RED 기본 사용

• input - function - output 노드
• inject와 debug 노드
• IoT Quick Start 노드
• IBM IoT 노드

 

IoT Foundation Quickstart 용 예제

1. 마이크로파이썬 mqtt library 설치

Firmware에 기본으로 탑재되어 있으나 참고용으로 작성

import upip
upip.install("micropython-umqtt.simple")
