SWE 4211 Labs

• Lab 1: Raspberry Pi
  • Virtual Box setup notes in case you've forgotten something
• Lab 2: Raspberry Pi Basic IO
  • Files for the lab (in case the classroom repository has not been set up for you): lab2-baseline.tgz Unpack with tar xf lab2-baseline.tgz. You can also unpack it with 7-Zip.
• Lab 3: Performance analysis for the Raspberry Pi
• Lab 4: Anticipation Game

Other notes:

• Connecting a Raspberry Pi 3 B+ to a laptop without Wi-Fi: direct Ethernet through the USB Ethernet adapter, plus a USB-to-serial console fallback. Note that USB gadget mode does not work on the Pi 3 B+.

It is often also useful to access your git repository on your pi or in your Linux VM. Steps:

• Use ssh-keygen to generate a key in your VM (or on your Pi). Press ENTER for each of the prompts, noting what file it creates.
• Type cat ~/.ssh/xxx.pub where xxx is the file created in the previous step.
• Log in to GitHub, open your account settings, find Access then SSH Keys. Add a new key, setting the name to the source (where it was generated) and the date. This helps you know what key is for what use. Paste the copied key into the appropriate window.
• In Linux, type

          eval `ssh-agent`
          ssh-add
  

  This will set you to use ssh to access your repository.
• Go to github, copy the SSH repository link, then clone it on your machine.
• Use sftp or any other appropriate method to copy the public and private keys to your other system. Pay attention to reproducing the directory and file permissions; these files cannot be visible to all users. chmod u=r is a good command to know. Then you should be able to check out the repository on that system as well.
