TinyOS Installition

Introduction TinyOS ? wireless embedded sensor network를 위해 디자인된 open-source operating system

설치 전 확인사항 C드라이브에 1GB의 용량이 있는지? Cygwin을 설치 한 적이 있는지? Windows 설정에서 temp 폴더의 위치를 1GB이상인 드라이브로 옮겨준다 Cygwin을 설치 한 적이 있는지? Uninstall & 레지스트리 삭제

Install Linux에 설치하기 Windows 에 설치하기

Windows에 설치하기 관련된 프로그램을 직접 설치 Installer 사용하기 완료 오류 체크 TinyOS & Tools : 무선 센서 네트워크를 위한 주요 OS 디버깅을 위한 Tool nesC : TinyOS를 위해 제작된 C 언어의 확장버전 Cygwin : Windows에서 Linux 와 같이 사용하기 위한 환경 AVR Tools : Atmel 의 AVR 프로세서를 위해 적합한 S/W 개발툴 java 1.4 JDK & java COMM 2.0 : Host PC application 과 포트 통신을 위한 것 Graphviz  : Make docs 로부터 만들어진 파일들을 보여주기 위한 것 Installer 사용하기 -http://webs.cs.berkeley.edu/users/users.php?download=1 완료 오류 체크 cd /opt/tinyos-1.x/tools/scripts; ./toscheck

TinyOS directory 구조(1)

TinyOS directory 구조(2) 기본 tinyOS application 과 테스트 프로그램  사용자 contribution 과 Xbow firmware  Document 와 온라인 가이드 개발자 유틸리티와 프로그램 ·TinyOS"Operation System", 모듈, 인터페이스  TinyOS 구성 인터페이스의 정의  Deluge, MinRoute 등  주요 라이브러리  Mote 플랫폼과 특정한 하드웨어 드라이버들  센서와 데이터 수집보드 드라이버  Timer 와 scheduler 같은 TinyOS 서비스  Active Message 같은 TinyOS 데이터 구조

Update Version 확인 Cvs 다운받기 “rpm –qa” 실행 후 tinyOS 홈페이지에 올라와 있는 최신버전과 비교한 후 다운로드 Cvs 다운받기 “cc2420dbk” 용 컴파일 플랫폼 받기위해 “cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/tinyos co tinyos-1.x“

환경 설정(1) Symbolic link 걸어주기 경로 변경해 주기 tinyos/tinyos-1.x/beta/platform/cc2420dbk ->/opt/tinyos1.x/tos/platform/cc2420dbk 경로 변경해 주기 /etc/profile.d/tinyos.sh 내용을 수정

환경 설정(2) “tinyos.sh” # script for profile.d for bash shells, adjusted for each users         # installation by substituting /opt for the actual tinyos tree         # installation point.         TOSROOT="/opt/tinyos-1.x"                                                   <<<<<<==========         export TOSROOT         TOSDIR="$TOSROOT/tos"         export TOSDIR         CLASSPATH=`$TOSROOT/tools/java/javapath`          export CLASSPATH         #We cannot set makerulesuntil we require make 3.8         makerules="$TOSROOT/tools/make/makerules"                         <<<<<<==========         export makerules                                                                    <<<<<<==========         # Extend path for java         type java >/dev/null 2>/dev/null || PATH=`/usr/local/bin/locate-jre --java`:$PATH         type javac >/dev/null 2>/dev/null || PATH=`/usr/local/bin/locate-jre --javac`:$PATH         echo $PATH | grep -q /usr/local/bin || PATH=/usr/local/bin:$PATH

Compile & 실행(1) Pc mote “make pc” 실행====compile /build/pc/main.exe 1(노드수)= 실행 “main.exe –h” ==== 실행 옵션 보기 mote “make cc2420dbk” 실행 실행은 mote에 다운로드 후

Compile & 실행(2) 그래픽 환경에서 시뮬레이션 보기 tinyos-1.x/tools/java/net/tinyos/sim/tinyviz

Compile & 실행(3) Mote(cc2420dbk)에 다운로드 하기 /build/cc2420dbk/main.ihex Avr studio 를 사용하여 다운로드
