Setting up wifi from command line

Hi, I installed a Gentoo (from here: https://github.com/sakaki-/gentoo-on-rpi-64bit) on my Raspberry Pi 4B. Having no screen and no keyboard, I took the Lite version and connected it to my router through Ethernet. I'm able to ssh to it. Now, I'm totally new to Gentoo (I picked it because it's the fi...

Re: Manjaro headless installation and wifi setup

Ah so I will need a screen and a keyboard if there are installation steps to follow before being able to ssh. Thanks.

ssh was enabled by default ...
So basically I can burn the Manjaro image on the SD card and hook up the Pi to my router through Ethernet, and get the wifi configured later?
What's the default root password?

Manjaro headless installation and wifi setup

I'm posting this in the Arch section since there isn't a section of Manjaro, I hope it's fine. I'm planning to install a Manjaro on my Raspberry Pi 4 (OS image here: https://manjaro.org/download/arm8-raspberry-pi-4-minimal/), but I don't have a screen nor a keyboard. With Raspbian I know how to enab...

Hi, I just got a Matrix Creator, which I want to use with a Raspberry Pi 3. I don't need MALOS, I just want to be able to program in C++, so using matrix-creator-hal. However I can't find any tutorial walking through all the steps from a clean Raspbian install to having matrix-creator-hal demos work...

Interacting with GPIO pins through /sys/class/gpio in C++

I have a function that gets me a file descriptor to /sys/class/gpio/gpioXX/value given a pin XX that I want to expose as an output. The goal is to then be able to write "1" or "0" on this file descriptor to control the pin. int setup(int number) { int fd = -1; // check is /sys/class/gpio/gpioXX exis...

When I use WiringPi and send a HIGH to this pin (in WiringPi this pin is numbered 0) the LED lights up,...

Getting the configuration screen again

Hello,

With Raspbian, the first time we start the Raspberry Pi we have a configuration screen where it is possible to select options (such as the keyboard layout). Once done, this screen never appears again. How can I get it again to change the configuration?

Thanks!
