DistributedFenceMonitor

Repository for the Embry-Riddle Aeronautical University Distributed Fence Monitor Capstone.

In Association with ICARUS and ERP.

How to Use

• The node source file is 'src/dfm_mkr1310.cpp'.
• The central-node source file is 'src/dfm_recv_mkr1310.cpp'.
• The central server file is 'interpreter/dfm_recv.m'
• The "main.cpp" is set up so that PlatformIO can compile and upload multiple sources separately, depending on the environment.
