LMU PEM2 20 21

This is the course PEM2 at LMU in Winter Term 2020/21.

Tasks

Current Task until 18.12.20

• Set up a web server on the Pi Zero that can be accessed from a computer/device in the same local network, i.e. calling a webpage.
  • Your web server should be able to read out GPIO states, e.g. you can read out how often a button was pressed in the last minute or when it was last pressed. Think about how to realize data persistence.
  • The user should be able to control actuators via the webpage, e.g. turning an LED on and off
  • Remember: You already collected and curated references for creating a webserver earlier (see Resources below)

• Explore options for sharing project source files within the team, e.g. versioning or continuous integration
  • You can use the LRZ gitlab: https://gitlab.lrz.de/
  • Alternatively, you could use a private or public GitHub repository (ask the other team members what they prefer)
  • One approach: Push code from your computer to the repository and pull the changes from the repository onto the Pi Zero
  • Alternatively setup a Continuous Integration / Continuous Deployment pipeline. This requires (way) more effort in the initial configuration but does not (ideally) require any manual intervention anymore afterwards when you push changes into your repo.
