Daisy Seed TDM for Eurorack PMOD

Welcome!

This repository provides an example implementation for using the Daisy Seed with TDM codecs (Time Division Multiplexing/multi-channel). It makes use of my libDaisy fork: libDaisy/audio-tdm-codec-ak4619 ( which extends libDaisy by adding support for TDM in general with the AK4619 codec as an first example. --> see Feature - TDM SAI/Codec Support #499

Features

• Shows, how to use Daisy Seed with TDM codecs.

• Using the amazing and highly recommended: EURORACK-PMOD by apfelaudio module!

• Driver Implementation:

  • Eurorack PMOD driver includes initialisation of Codec + a simple LED driver (+VU meter)
  • The libDaisy fork includes a driver for the codec_ak4619

Prerequisites

1. Install Dependencies:
   • Daisy toolchain and environment

Getting Started

1. Clone the Repository (with submodules):

   git clone https://github.com/heartwerker/seed_tdm_example_eurorack_pmod.git --recursive

2. Connect Eurorack-PMOD to Daisy Seed:

   The PMOD pinout can be found on the silkscreen on the back side of the board.

   PIN Mapping

   Daisy Seed - PMOD

   1) D25 - SDI (AK4619VN SDIN1)
   2) D11 - SCL (I2C SCL for AK4619VN CODEC, EEPROM, LED + JACK IO expanders)
   3) D26 - SDO (AK4619VN SDOUT1)
   4) D12 - SDA (I2C SDA)
   5) D27 - LRCK (CODEC clock line)
   6) 3V3 - PDN (CODEC power down, -- HIGH means everything is on)
   7) D28 - BICK (CODEC clock line)
   8) D24 - MCLK (CODEC clock line)
   9) GND - GND
   10) GND - GND
   11) 3V3 - 3V3 IN
   12) 3V3 - 3V3 IN
