Christmas tree controller (ASIC)

This project 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)

Architecture

This design is based on Caravel user project template.

Below is a representation of the architecture:
