S/PDIF optical output for Teensy 3.1.

Parts Required:

  Everlight PLT133/T6A connector, Digikey 1080-1434-ND
  Capacitor, 0.1 uF, 0805 size, Digikey 1276-1003-1-ND

The Teensy Audio library now officially supports S/PDIF output. WAV File Player Example (in Arduino: File > Examples > Audio > WavFilePlayer) has been updated to show how to use it.

The S/PDIF output object is now available in the Audio System Design Tool, so you can easily create arbitrarily complex audio projects with digital S/PDIF output.

Special thanks to Frank Boesing for developing the S/PDIF encoding code!

Ongoing development conversation here:

The S/PDIF signal is output on pin 22. An inexpensive connector (Digikey 1080-1434-ND), or simply a red LED, can be used to couple the digital audio to an optical TOSLINK cable! Resistors and a small transformer can also be used, for non-optical RCA connector S/PDIF.

This is the little test board shown here:

Parts used on the board are:

    LM7805 voltage regulator        Digikey LM7805ACT-ND
    B130 Schottky diode             Digikey B130-FDICT-ND
    140 mA PTC fuse                 Digikey 507-1495-1-ND
    100 ohm 1/4 watt resistor       Digikey 100XBK-ND
    DC power jack                   Mouser 163-7620E-E
    1uF 0805 capacitor              Digikey 1276-1066-1-ND

An older version of this board had a minor error. You can easily identify the board version by the location of the 100 ohm resistor.

Newer Version Available

A new version of this board is available. It fixes problems with the reset signal and power jack.

You can easily identify the board version by the location of the 100 ohm resistor.

This PCB has the display RST signals connected to pin 8, not 3.3V. This special step is needed to make it work.
