Christmas tree controller (ASIC)

This design implements a Christmas tree controller that include four dedicated modules :

  • Infrared receiver (protocol NEC)
  • StepMotor controller (full-step, half-step, with strenght control)
  • Led string controller (compatibles WS2812B)
  • Pseudo-random generator (32bits)

The purpose of this System On Chip (SoC) is to control a Christmas tree. This controller allows, thanks to an infrared remote control, to control an garland of RGB LEDs as well as its rotating star at its top.

Architecture

This design is based on Caravel user project template.

Below is a representation of the architecture:
