NeuroSky MindWave Mobile 2 and M5Stack Core2 connection

  • Semester work for subject ZPI at the faculty of applied sciences at the University of West Bohemia. Winter semester 2022.

  • M1: main controller that connects to the EEG headset, parse data and output them to Serial and to the second controller M2 through UART

    • /M1/M1/M1.ino - main, actual version
    • /M1/M1/icons.cpp - icons in bitmap for GUI
    • /M1/other_versions/2_threads - verison with 2 threads and loop but not working properly
    • /M1/other_versions/without_multithreading - older verison just with loop, it doesn't have all features

  • M2: second controller that send request to M1 for data (0-4) and output them on the screen

    • /M2/M2.ino - main, actual version
    • /M2/icons.cpp - icons in bitmap for GUI

  • M2Ext: second controller that send request to M1 for data (0-4) and output them on the screen and MQTT broker

    • /M2Ext/M2Ext.ino - main, actual version
    • /M2Ext/icons.cpp - icons in bitmap for GUI
    • /M2Ext/flows.json - Node-red flow exported via json. Uses Node-red Dashboard extension
