install the Lab11 version of tinyos-main:\n\n    git clone https://github.com/lab11/tinyos-main.git\n    cd tinyos-main/tools\n    ./Bootstrap\n    ./configure\n    make\n    sudo make install\n\n\n### 2) Clone yours truly:\n\n    git clone https://github.com/lab11/hemera.git\n\n\n### 3) Add to `bash.rc`:\n\n    export TINYOS_ROOT_DIR=\u003cpath to\u003e/tinyos-main\n    export TINYOS_ROOT_DIR_ADDITIONAL=\u003cpath to\u003e/hemera/tinyos:$TINYOS_ROOT_DIR_ADDITIONAL\n\n\n### 4) Set up the RaspberryPi (optional, but recommended):\n\nA modified RaspberryPi can be utilized to receive and forward data to GATD. \nIf you choose to use one, you need the [Linux CC2520 Driver](https://github.com/ab500/linux-cc2520-driver) for the RPi.\nInstead of installing this manually, it is suggested to download \u0026amp; install the preinstalled image from [this torrent](https://github.com/lab11/raspberrypi-cc2520/tree/master/torrents).\nGo to https://github.com/lab11/raspberrypi-cc2520 for additional details on setup.\n\nClone the RPi repo:\n\n    git clone https://github.com/lab11/raspberrypi-cc2520.git\n\nAdd to `bash.rc`:\n\n    export TINYOS_ROOT_DIR_ADDITIONAL=\u003cpath to\u003e/raspberrypi-cc2520/tinyos:$TINYOS_ROOT_DIR_ADDITIONAL\n\n\n### 5) Get the compilers\n\nIn order to compile the TinyOS code you need the msp430 and the ARM compilers\n\n\nSense Stuff\n-----------\n\nAfter you have finsihed the above setup, you should be ready to install apps on the Hemera board.\n\nThe basic sense \u0026amp; broadcast app is HemeraAM. To install it, go to `\u003cpath to\u003e/hemera/tinyos/apps/HemeraAM` and follow the README. \n\nTo receive \u0026amp; forward data to GATD on the RPi, go to `\u003cpath to\u003e/hemera/tinyos/apps/RpiGatdForwarder` and follow the README.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbradjc%2Fhemera","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbradjc%2Fhemera","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbradjc%2Fhemera/lists"}
