Onboarding-Task

A simple task to introduce the processes used in the Embedded subsection

Introduction

To begin, you will need to download the following software:

• Visual Studio Code
• C/C++ Extension
• PlatformIO

If you don't already have it, download Git as well

Repository Setup

Once you've installed the required software, proceed with setting up the sample repo:

1. Open a terminal and clone the repository:

git clone https://github.com/GryphonRacingFSAE/Onboarding-Task.git

2. Enter the repo directory:

cd Onboarding-Task

3. Create a new branch and switch to it:

git checkout -b YourName  # NOTE: please name the branch accordingly

4. Open the repo folder in Visual Studio Code
5. Ensure the correct branch is selected in the bottom-left (e.g. YourName)
6. Select the PlatformIO icon from the left toolbar and wait for the project to initialize

Task Instructions

You will be creating a simple morse code program using the ESP32's built-in LED:

• The built-in LED can be enabled through GPIO 2 → pinMode(2, OUTPUT);
• The LED can be turned on/off by setting the pin's voltage (HIGH/LOW) → digitalWrite(2, HIGH);
• The default program delay is based on milliseconds (1000ms = 1s) → delay(1000);

Program Parameters

1. The task will be to spell the word MISSISSIPPI
2. The morse code system should work on the basis of a default time unit (300ms)
3. The following time unit multiples should be used for each feature:

Feature	Time (units)
Dot	1
Dash	3
Space between dots/dashes	1
Space between letters	3
Space between words	7

Notes:

• The chosen word includes a variety of repeating letters, which should encourage functional programming
• Since there is only one word, please use a length of 7 time units at the end of the word and have it loop

Submission Instructions

Once your code is working, record a video or perform an in-person demo, then:

1. Stage your changes:

git add .

2. Commit your changes:

git commit -m "Add morse code implementation"  # NOTE: please name the commit accordingly

3. Push your changes:

git push origin YourName

4. Create a pull request for your branch here
