Virtual Embedded Systems Lab

In this lab we will introduce you to some tasks that you will likely perform when you start working as an embedded systems engineer. We will cover the following in these labs:

1. GPIO Output
2. GPIO Input based on polling and interrupts
3. Emulating SPI using GPIO, for when a hardware SPI is not present in a device
4. Writing a device driver for a peripheral attached with SPI
5. Writing a state machine based orchestration system

What to do in the labs

In each of the labs you will have functions marked with @todo, you need to implement those functions.

But before we jump in let's Setup our systems so that we can run the labs themselves.

Setup

1. Install Docker and Docker-Compose

   Windows/Mac: Docker Desktop for Windows/Mac

   Linux: Docker CE and Docker Compose

2. Install VSCode

3. Install Remote Containers extension for VSCode

4. Download the lab materials.

5. Open the folder using VSCode containers

   Note: When you open the lab the very first time a Docker Image and container will be built. This takes quite some time based on your internet speed and computer's performance metrics; but subsequent runs will be only using the image as well as the container so will be much faster.

6. Run Lab 1 Part 1 by running the lab run task

   1. Bring up the commands menu by pressing Ctrl+Shift+P
   2. Write Tasks: Run Task
   3. Run the Run Lab Task
   4. Select and run Lab_1_Part_1
   5. Open "No VNC" in your browser by going to http://127.0.0.1:6080/vnc.html
   6. Enter the password "embedit" to connect and view the output
