This master will contain the Python scripts located in the \"src/master\" folder.\n\nThe other Pis will be \"slaves\". They will contain the Python scripts located in the \"src/slave\" folder.\n\nAfter copying the files, the result will (probably) be a star network topology in which slaves \"vomit\" data towards the master.\n\n![LittleSister logo](documentation/networkTopo.png)\n\n## How to set up \u0026 run LittleSister\n### Master Raspberry Pi\n1. Change the network settings (IP of master and UDP port) in PictureSettings.py of master source code folder, if necessary.\n2. On the master Raspberry Pi, launch **LaunchMaster.py**.\n\n### Slave Raspberry PI\n1. Change the settings in PictureSettings.py of source source code folder, if necessary.\n2. On a slave Raspberry Pi, launch **LaunchSlave.py**.\n\n## Python Dependencies\n\nLittleSister has the following Python dependencies:\n\n* imghdr\n* io\n* os\n* PIL\n* select\n* socket\n* sys\n* StringIO\n* time\n\n![LittleSister logo](documentation/logo.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdakostu%2Flittlesister","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdakostu%2Flittlesister","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdakostu%2Flittlesister/lists"}
