EEE3097S Design Project

Welcome

Welcome to our EEE3097S design project. This project is proudly designed by Natasha Soldin and Rory Schram.

Introduction

The following project design is for an ARM based digital IP using an STM32F051-microcontroller. This design aims to retrieve, compress and encrypt data from an Inertial Measurement Unit (IMU) sensor. This type of sensor includes an Accelerometer, a Gyroscope, a Magnetometer and a Barometer. This design will be implemented as a buoy installed on an ice 'pancake' in the Southern Ocean to collect data about the ice and wave dynamics.

This data will then be transmitted using the Iridium communication network, which is a global satellite communications network. However, this is extremely costly and therefore the data would need to be compressed to reduce its size. The data is also encrypted for security purposes.

Repository Contents:

• A paper design: that outlines the theoretical planning for the project and inludes: a requirement analysis, subsystem design, acceptance test procedures and development timeline.
• A first progress report: that outlines the simulated practical experimentation for the project and includes: a data analysis, experiment setup, results and acceptance test procedures.
  • Data Analysis: jupyter notebook that plots the time and frequency domains and histograms of the provided sample 'Walking Around' data.
  • Code: includes the python scripts used in the simulated software implementation of the project.
• A second progress report: that outlines the practical experimentation for the project and includes: an IMU module, experiment setup, results and acceptance test procedures.
  • Code: includes the C scripts used in the practical hardware implementation of the project.
  • Excel Speadsheets: inlcuding the results of the IMU validation tests and IMU comparison included in the IMU module.
• A final report: that contains the final handin for this course.
  • Code: includes the entire code base for the project to work in a "testing state". This testing state is what was used to generate the final results for the compression and encryption tests.

Required Hardware

To get started working on this project, the following hardware is required:

Hardware	Quantity
ICM-20649 Module	x 1
STM32f051 Discovery Board	x 1
FTDI Adaptor	x 1
Micro-USB	x 1
Mini-USB	x 1
Male-to-Female Jumpers	x 10
Male-to-Male Jumpers	x 10
Computer to Code	x 1

Note: The quantity of the jumpers stated is far beyond what is actually needed, however, jumpers are a really useful tool for debugging and so having many of them is highly recommended.

Required Software

As well as the above mentioned hardware, the following software/tools are needed:

Hardware	Quantity
STM32 Cube IDE (Or equivalent such as VS Code)	x 1
Serial Port Monitor (Putty on Windows, or SerialTools on Mac)	x 1

Note: The latest STM software needs to be loaded onto the STM32f051 for this project, this can be done with the STM32 Cube IDE software.

Connecting the Hardware

The pins on the WaveShare SenseHAT that need to be connected to the STM32f051 are the following:

WaveShare HAT Pin	STM32f051 Pin
GND	GND
3.3V	3.3V
SDA	PB7
SCL	PB6

The pins on the FTDI adaptor that need to be connected to the STM32f051 are the following:

FTDI Adaptor	STM32f051 Pin
GND	GND
5V	5V
TX	PA10
RX	PA9

Run our Program

To run our program and test if all the connections are working properly, create a clone of the repository to your local machine, do this by running the following code:

cd storage_directory

git clone https://github.com/TashiSoldin/EEE3097S-Project.git

To get the latest version of the main branch, run:

git pull origin main

Open the STM32 Cube IDE or your preferred choice of development software and open the project file in the Final Report folder called "code". Build the code, and then upload it to your STM32f051 while it is plugged in to your computer.

The code should now be uploaded to the STM32f051. To moniter the ouput of the board connect the micro-usb from the HAT to your computer, a serial port monitor is needed. On a mac run the following command:

screen /dev/tty.usbserial-0001

This will open a serial monitor in the terminal which can be used to monitor the output of the HAT. Example output will look like the following:
