  • The script that sets up a Hardware Lab computer to connect to a Raspberry Pi: lab-network.py

    Download this script on the host computer, and run it with python lab-network.py. Then connect your Raspberry Pi and wait for it to assign an IP address to the host computer.

  • Connect to the Raspberry Pi from Linux or MacOS with the command:
    ssh -X compsci@172.16.1.1

  • Connect to the Raspberry Pi from Windows with the PuTTY program: PuTTY for Windows — IP address "172.16.1.1" ; account "compsci".

  • If you want to open GUI windows (such as the SciTE editor), then also install ; and in PuTTY, go to "connection→SSH→Enable X11 forwarding".

    The "Xming" software is an X Window server. "PuTTY" is an remote-connection tool that opens an SSH session to a host such as the Raspberry Pi. Once you are logged in, you can start a GUI program (such as an editor) that will connect to Xming to display the window.

  • 64-bit Devuan operating system for Raspberry Pi: devuan-mate

    Download this .img file, and burn it onto a 16GB microSD card. Use it for the Raspberry Pi.

Software

SPIM and Linux — MIPS architecture simulator
Linux-Spim.ova
Virtualbox "appliance" — a Linux virtual machine with QtSpim installed. Also includes mips-gcc cross-compiler.
SciTE — text editor
http://www.scintilla.org/SciTE.html — homepage for the SciTE software
The SciTE programmer's text editor. Cross-platform (Windows, Linux), a good replacement for "Notepad".
Vim — text editor
http://vim.org/ — homepage for the Vim editor
Cross-platform (Windows, Linux, MacOS); an upgrade of the basic editor found on Linux and MacOS. For real "heavy lifting". Very powerful but takes some getting-used-to.
