Linwood Whaley's assembly code to run animations on his 4 x 4 x 4 LED cube
Raw
led-cube-4x4x4.ino
/*
led-cube-4x4x4
Arduino UNO or Nano
MCP23017 I/O expander controlled by I2C
64 leds in a 4 by 4 by 4 by 4 arrangement
16 2N3906 pnp transistors controlling led anodes connected to MCP23017 GPIO port outputs---low on output turns transistors on
4 2N4401 npn transistors controlling led cathodes connected to 4 pins of Arduino board---high on output turns transistors on
MCP23017 address is 0x20
ATMEGA328P assembly language used in this program---for speed and memory savings
