This guide details my experience of installing i3wm on Ubuntu 22.04 LTS.
Note: My Ubuntu Desktop environment was already set up. All the apps available in the default Ubuntu window manager will also be accessible in i3wm, which is amazing because you can switch back to the default Ubuntu window manager anytime.
Open the terminal and run the following command:
| // A basic example of queue written in C | |
| // Useful for small microcontrollers | |
| // Tags: Arduino | Atmega | AVR | STM32 | |
| #include <stdio.h> | |
| #include <stdint.h> | |
| // Maximum number of items in queue | |
| #define QUEUE_MAX 5 |
| // Notice: 8 Mhz frequency is expected | |
| #define SONIC_DDR DDRC | |
| #define SONIC_PORT PORTC | |
| #define SONIC_PIN PINC | |
| #define SONIC_TRG_PIN PINC0 | |
| #define SONIC_ECHO_PIN PINC1 | |
| #include <avr/io.h> | |
| #include <util/delay.h> |
