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