  • Description: Plays bad apple over a Piezo Speaker connected across io_out[1:0]. Based on https://github.com/meriac/tt02-play-tune
  • GitHub repository
  • Clock: 12000 Hz

How it works

Converts an RTTL ringtone into verilog and plays it back using differential PWM modulation.

How to test

Provide 12kHz clock on io_in[0], briefly hit reset io_in[1] (L->H->L) and io_out[1:0] will play a differential sound wave over piezo speaker (Bad Apple)

External hardware
