Raspberry Pi Setup

This is a quick guide to set up a Raspberry Pi for IO control shenanigans.

Pick an SD card and write an image plus SSH config on your laptop.

Image

https://www.raspberrypi.com/software/operating-systems/

Raspberry OS Lite, possibly 64-bit for Pi 3 or later

unxz the image, then dd; e.g.:

sudo dd status=progress \
    if=2024-11-19-raspios-bookworm-armhf-lite.img \
    of=/dev/mmcblk0

SSH

• copy .ssh dir; cp -r ssh-dir rootfs/home/pi/.ssh
• touch bootfs/ssh

Interfaces

This is done from the running system.

• raspi-config -> 3 Interface Options
• configure as you need :)
• reboot to apply (config is written to /boot/cmdline.txt / /boot/config.txt)

Scripts

Do your Python foo...

Services

Example:

You probably need the type exec or simple:
