Requirements

Hardware

• Arduino Uno
• 8×8 LED Matrix MAX7219
• 5 males to females pin cables

Software

• Aseprite
• PlatformIO
• (The project relies on the LedControl library : https://github.com/wayoda/LedControl)

How to use

• Use Canva.aseprite and don't move it to another folder (it uses the path of this file to generate frames.txt)
• In Aseprite, drop the file ./aseprite/script/ByteConverter.lua in the Aseprite script folder
• Upload main.cpp to the Arduino Uno
• In Aseprite, run the script ByteConverter to launch the FramesAPI.exe and display the sprites to the LED matrix

To Do (if i ever decide not being lazy)

• Use binary instead of a txt file to send the bytes
• Add some contrast using the luminosity
• Fix the Bug that mess up the conversion to bytes when one row or column is empty (contains no pixel) in the sprite
