A repository containing the source code for my undergraduate senior project at the University of Pittsburgh at Johnstown. The Cycle Statistic Tool is a data recording device attached to the frame of a bicycle. From this position, the Cycle Statistic Tool's network of sensors collects live metrics about the vehicle. Subsequently, the data is transmitted to a companion mobile application that is installed on a user’s smartphone. The Arduino hardware was programmed using C++. The cross-platform mobile application was programmed using the .NET/Xamarin platform and C#.
The senior project final report provides an overview of the Cycle Statistic Tool's engineering process.
The Cycle Statistic Tool final demonstration was presented on 04/20/21. A YouTube video made by the project team was used to demonstrate the project's functionality at this time.
Written in C# using the Xamarin platform.
For documentation of the mobile application design, check out the Software Requirements Specifications.pdf file.
Written in C++.
Compiling Insructions:
You will need the following devices from the Arduio Device Manager: Arduino Nano IoT 33 Core
You will need the following libraries from the Arduino Library Manager: ArduinoBLE Adafruit_GPS Adafruit_EPD Adafruit_GFX SparkFunLSM6DS3
Delete 'main.cpp' from both the final and secondary microcontroller folders. Those files were placed there only for readability on GitHub. The files named 'final_primary_microcontroller_code.ino' and 'secondary_primary_microcontroller_code.ino' are equivalent to their respective 'main.cpp'.
Place both the /final_primary_microcontroller_code/ folder and /secondary_primary_microcontroller_code/ folder in /Documents/Arduino/
Open the .ino for the microcontroller that you want to program
Compile and upload code.
Comprehension:
main (primary) calls setup functions, polls BLE, and fires event-lists.
CSTDefinitions.h defines constants used throughout the code. includes bluetooth ID's, update frequencies, array indices
CSTExterns.h externs
display.h contains all of the code that operates the display. includes setup code and update code. just call updateDisplay(), the function will pull all necessary data.
PrimaryBLEHandling.h contains function for setting up BLE (adding services, characteristics, names etc.). defines handlers that are called by BLE.poll() in the main loop.
Stat.h simple wrapper that updates BLE characteristics and records a rolling avg.
updateEvent.h abstract class that is used to defines what happens when a sensor is updated. updateEvents should also update BLE Stats (and thereby characteristics) when new measurements are taken.
