Embedded Coding Challenges

This repository is a collection of problem statements and supporting infrastructure to help you practise your "Embedded Systems Programming" muscle.

We will keep adding new problems from time to time.

Getting started

All problems need to be solved in the GitHub codespaces. Be sure to be logged into your GitHub account.

Create Codespace

To create/start the codespace, follow these steps:

1. click on <> Code button.
2. click the Create codespace on main button

wait for the codespace to be setup.

Reopen the codespace

In the <> Code button, you should see the name of the previous codespace that was created. Select Open in Browser from the dropdown menu next to it.

The Warmup Challenge

Important

Be sure to complete this challenge before anything else. It is designed to confirm that the setup works as expected.

Once the codespace is setup. Open a terminal and change the working directory to warmup.

cd warmup

Open the main.c and following the challenge details there. Most likely, you'll need to edit the // TODO to print Hello, World!.

If you are new to C/Embedded Programming, simply replace // TODO with printf("Hello, World!");

Next, from the terminal, compile and run the tests.

1. Compile the changes

   gcc main.c

2. Run tests

   checkbrah
   

The automated code checker will run tests on the compiled code and present you with stats.

Checker

checkbrah is a simple chacker we made that will feed inputs, capture the output and compare it to the expected ones. It uses the loacally saved tests.yaml to infer the inputs and expected outputs.

When you run it, you should see one of the following

Fail

$ checkbrah
PASS: 0/1
FAIL: 1/1
-------
Oh No!! Some tests failed 🥺

Pass

$ checkbrah
PASS: 1/1
FAIL: 0/1
-------
🎯 You Nailed it!!
Move on to the next challenge...
