Raspberry installation notes
Barebone installation (Raspbian GNU/Linux 11 (bullseye) as of July 2023)
Install Raspberry on blank SD-card
Use Raspberry pi imager (download from https://www.raspberrypi.com/software/)
rpi-imager
First configure settings: click the gear icon, and set:
- enable ssh, hostname, English language, Danish keyboard, possibly SSID, time zone, username (local) and password (remember to spell the password correctly).
then
Select operating system 'Raspberry Pi OS lite' and storage, an empty SD-flash of at least 16GB, then write.
When finished, mount the SD into the Raspberry
Get in contact with Raspberry
If everything is configured as above, then you just need to figure out the IP. On a Linux computer, you can find the Raspberry IP address using (if on the same local net):
sudo apt install net-tools nmap nmap -sP 192.168.2.0/24
else
You need a screen and keyboard.
Log on to the Raspberry Pi
$ ifconfig
eth0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
...
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
...
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.197.217.175 netmask 255.255.252.0 broadcast 10.197.219.255
inet6 fe80::f620:b431:69cc:44f4 prefixlen 64 scopeid 0x20<link>
ether dc:a6:32:f4:0e:a4 txqueuelen 1000 (Ethernet)
RX packets 486 bytes 41505 (40.5 KiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 421 bytes 43403 (42.3 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
In this case, the IP4 (inet) is 10.197.217.175.
If you don't get an IP, the wifi may not be set correctly (see the Network setup).
Additional packages
Install the following packages:
libreadline-dev libopencv-dev libgpiod-dev gpiod cmake subversion aptitude telnet ntp ntpdate nmap lsof libpaho-mqtt-dev libpaho-mqttpp-dev (if not available, then not needed) python3-paho-mqtt python3-opencv python3-setproctitle mosquito mosquitto-dev mosquitto-clients libusb-dev libcli11-dev (maybe not available) sudo apt install libreadline-dev libopencv-dev libgpiod-dev gpiod cmake subversion aptitude telnet ntp ntpdate nmap lsof python3-paho-mqtt libpaho-mqtt-dev python3-opencv python3-setproctitle mosquitto mosquitto-dev mosquitto-clients libusb-dev libcli11-dev
and, if libcli11-dev is not available
Install command line interface library (if not found by 'apt install libcli11-dev')
cd cd git git clone https://github.com/CLIUtils/CLI11.git
The library is 'header-only', and the makefile for Raspberry looks in ~/git/CLI11 for the file, so no need to build.
Configure Mosquitto
At installation, the Mosquitto server does not allow remote access.
A complete configuration file can be found here: https://github.com/eclipse-mosquitto/mosquitto/tree/master
Only two options are needed, so we make a set of local options:
sudo nano /etc/mosquitto/conf.d/robobot.conf
Insert these lines (insert from clipboard is Ctrl+Shift+v in nano)
listener 1883 allow_anonymous true
Save and restart mosquito
sudo service mosquitto restart
