xorchitecture code: byte.observer a 256b x86 Linux (ELF) framebuffer intro with sound for Outline 2021 watch here: https://www.youtube.com/watch?v=6CLNXC4yCD8 github: @nwoeanhinnogaehr https://byte.observer system requirements: 1. Framebuffer access. Press ctrl-alt-Fx to switch to a virtual terminal and log in. Make sure you are in the video group so that you can access the framebuffer. You can add yourself to the group with $ sudo usermod -a -G video $USER After adding yourself to the video group, you will need to log out and back in for the changes to take effect. You can test if you have framebuffer access by doing: cat /dev/urandom > /dev/fb0 2. Framebuffer resolution of 1024x768x32. You can set this using the fbset command. 3. Working ALSA audio with 8 channel support. This demo uses the aplay command for audio playback. You can test if it is working by running: $ aplay -c8 /dev/urandom Note: depending on your configuration, aplay may not work if you are logged in as root. after the above are satisfied, do: $ ./xorchitecture ALTERNATIVE TO FRAMEBUFFER: If your framebuffer isn't working or cannot be set to the required resolution, there is a simple C program included that uses SDL2 to emulate a framebuffer device. You will still need aplay working to use this emulated version. To run the framebuffer emulator version, do: $ fbe/xorchitecture-fbe.sh to build: $ nasm -f bin xorchitecture.asm -o xorchitecture $ chmod +x xorchitecture
