Source code for LEDcube

This code is for board versions 1.*

Setup

  1. Install the Arduino IDE (See www.arduino.cc)

  2. Copy the content of the folder bootloaders into

    • Windows: <Arduino Installation>/hardware/arduino/avr/bootloaders/
    • Mac OS X: /Applications/Arduino.app/Contents/java/hardware/arduino/avr/bootloaders/
  3. Copy the folder mega32 to

    • Windows: <Arduino Installation>/hardware/arduino/avr/variants
    • Mac OS X: /Applications/Arduino.app/Contents/java/hardware/arduino/avr/variants
  4. Append the following text to

    • Windows: <Arduino Installation>/hardware/arduino/avr/boards.txt
    • Mac OS X: /Applications/Arduino.app/Contents/java/hardware/arduino/avr/boards.txt
    ledcube.name=LEDcube
    ledcube.build.mcu=atmega8
    ledcube.build.f_cpu=14745600L
    ledcube.build.core=arduino
    ledcube.upload.tool=avrdude
    ledcube.upload.protocol=arduino
    ledcube.upload.speed=19200
    ledcube.bootloader.tool=avrdude
    ledcube.bootloader.unlock_bits=0x3F
    ledcube.bootloader.lock_bits=0x0F
    
    ledcube.menu.cpu.atmega8=ATmega8 (4x4x4)
    ledcube.menu.cpu.atmega8.upload.maximum_size=7168
    ledcube.menu.cpu.atmega8.upload.maximum_data_size=1024
    ledcube.menu.cpu.atmega8.build.mcu=atmega8
    ledcube.menu.cpu.atmega8.build.variant=standard
    ledcube.menu.cpu.atmega8.build.board=X4
    ledcube.menu.cpu.atmega8.bootloader.low_fuses=0x3f
    ledcube.menu.cpu.atmega8.bootloader.high_fuses=0xca
    ledcube.menu.cpu.atmega8.bootloader.file=atmega8/ATmegaBOOT_14MHz.hex
    
    ledcube.menu.cpu.atmega32=ATmega32 (8x8x8)
    ledcube.menu.cpu.atmega32.upload.maximum_size=30720
    ledcube.menu.cpu.atmega32.upload.maximum_data_size=2048

    ledcube.menu.cpu.atmega32.build.board=X8
    ledcube.menu.cpu.atmega32.bootloader.low_fuses=0x3f
    ledcube.menu.cpu.atmega32.bootloader.high_fuses=0xca
    ledcube.menu.cpu.atmega32.bootloader.file=atmega/ATmegaBOOT_168_atmega32_14MHz.hex
    
  5. Fix Serial library for ATmega32. Open

    • Windows: <Arduino Installation>/hardware/arduino/avr/cores/arduino/HardwareSerial.cpp
    • Mac OS X: /Applications/Arduino.app/Contents/java/hardware/arduino/avr/cores/arduino/HardwareSerial.cpp

    Replace:

    #if defined(__AVR_ATmega8__)
       config |= 0x80; // select UCSRC register (shared with UBRRH) 
    #endif
    

    With:

    #if defined(__AVR_ATmega8__) || defined(__AVR_ATmega32__) || defined(__AVR_ATmega16__)
       config |= 0x80; // select UCSRC register (shared with UBRRH) 
    #endif
