After a bit of experimenting, it seems like pure java code to manage GPIO is too hard for my raspberry pi zero. It's under 100% cpu load pretty much after the tiniest loop. There can probably be optimizations but I thought "since all other libraries fall back to native calls, I'll just use PI4J ."

To install RPi.GPIO python library, type the following commands on terminal window of your Raspberry Pi − sudo apt-get install python-dev sudo apt-get install python-rpi.gpio Almost all the latest versions of distributions have RPi.GPIO already installed.
I know it's possible to write and read GPIO values using the command line: echo 1 > /sys/class/gpio/gpio0/value. for example, puts the GPIO 0 pin on high. Now, for reading, you use cat. However, this restricts me to polling and does not prevent me from missing a state inbetween poll events.
04.03.2021 · gpio readall reveals the current status of all GPIO pins. The meaning of the columns is as follows: BCM: This column refers to the nomenclature of the Broadcom CPUBCM2835, but which does not match the usual Raspberry Pi names! If you want to refer to this nomenclature for gpio commands, you must always use the -g option.

Raspberry Pi OS commands. Most of the commands from this post are basically Linux commands. But Raspberry Pi OS has some exclusive ones that I will introduce. These are not all essentials, but you may not know them even if you are good with Linux: raspi-config: This tool allows you to manage all the configuration from a terminal or an SSH ...
You can also use the tool with Configuring Remote GPIO to query remote Raspberry Pi’s: $ GPIOZERO_PIN_FACTORY = pigpio PIGPIO_ADDR = other_pi pinout Or run the tool directly on a PC using the mock pin implementation (although in this case you’ll almost certainly want to specify the Pi revision manually):
