Description

Cet objet à été conçu sur les bases d’un témoignage perturbant à la date du 27 juin 2007 sur le forum ████ par l’utilisateur Chri████4. Il y fait mention d’un jeu à boire avec ses amis où ils auraient décidé d'invoquer Satan aux alentours de 23h42. La soirée aurait tourné en une cruelle mission de subjugation du malin avec pour seule arme l’alcool en grande quantité qu’ils avaient préparé pour faire la fête. Suite à cette affaire le service d’exorcisme V-696 (avec à sa tête Jean-███II) aurait procédé à une énorme commande de Sobieski.

À travers le projet Mega Drinking Machina Adventure™ nous voulons faire vivre à nos très chers futurs utilisateurs une simulation familiale de cette aventure hors du commun. Une compilation de jeux à boire allant de 1 à 5 joueurs sera proposée, avec une mise en place intuitive et rapide. Sur batterie, lumineux et facile à transporter, il deviendra votre meilleur outil pour pimenter vos soirées peu importe le contexte.

Installation (AVR)

Debian Based Linux :
- Install avr-gcc :
  sudo apt-get install gcc-avr binutils-avr avr-libc
- Install avr-dude :
  sudo apt-get install avrdude
Macos Unix :
- Install brew (for noobies) :
  rm -rf $HOME/.brew && git clone --depth=1 https://github.com/Homebrew/brew $HOME/.brew && export PATH=$HOME/.brew/bin:$PATH && brew update && echo "export PATH=$HOME/.brew/bin:$PATH" >> ~/.zshrc
- Install avr-gcc :
  brew tap osx-cross/avr
  brew install avr-gcc
- Install avr-dude :
  brew install avrdude

Usage

Setup port :
ls /dev/ > /tmp/file1
then connect board
ls /dev/ > /tmp/file2
diff /tmp/file1 /tmp/file2
will give you the port
paste the given port to the PORT variable of the makefile
Upload to board :
make coffee for build and upload
make debug for debuging
make help for other options

Visual Studio Code Linter

Install C/C++ extension
Configure C/C++ extension for avr :
Type C/C++: Edit Configurations (JSON) in Command Palette
- Linux :
  Add "/usr/lib/avr/include/**" line to includePath
- Macos :
  Add "/Users/tmp/.brew/Cellar/avr-gcc@9/9.3.0_2/avr/include/**"
  on labelec macs
  or
  /System/Volumes/Data/usr/local/Cellar/avr-gcc@9/9.3.0_2/avr/include/**
  (on real macs)
  to includePath.
  If this line doesnt work find "avr/io.h" file with find / -name io.h
  Add the containing folder to includePath (like Linux method)

Project Functionalities

Leds Control

Prerequisites

ft_pin_mode(led_pin, FT_OUTPUT);

Leds Variables

char buffer (size = number of leds * 3)

Color Attribution

The color format is uint32_t : 0xLLRRGGBB
LL : Luminosity (0x01 to 0xFF, or 0x00 to ignore)
RR : Red (0x00 to 0xFF)
GG : Green (0x00 to 0xFF)
BB : Blue (0x00 to 0xFF)

Usefull Functions

uint8_t *feed_one_pixel(uint16_t pixel_index, uint8_t *pixels, uint32_t color)
feed the selected pixel with the color
led_send_data(51, pixels, pixels_number);
send data to the leds

Questions

How big is the MDMA PCB?

It measures 235 × 180 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MDMA use?

138 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the MDMA KiCad files?

From the juthomas/Electronics_MDMA repository on GitHub, at the commit this page was made from: the board is MDMA_KICAD_V2/MDMA/MDMA.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the MDMA design in my own project?

Its repository states no licence, so its author keeps all rights: ask juthomas before reusing the design.
