Basic Operation

The basic operation of the Qwiic Tsunami only requires the use of the trigger pins to interact with the board. For the example in the next section, users must insert their configured µSD card with *.wav files and connect their headphones to the Qwiic Tsunami.

Inserting the µSD Card

Inserting the µSD card, prepared from the previous section, is straight forward. The µSD card slot contains a spring-loaded locking mechanism:

  • Insert the card and press in to lock the card into the slot.
  • Press in to unlock and remove the card from the slot.

Connecting the Headphone Jack

Note: If users experience problems with the audio output to their headphones, there are different headphone connector standards that might be the issue. If that is the case, users only need to swap the connection from SLEEVE pin on TRRS 3.5mm breakout board to the RING2 pin.

This part of the guide will demonstrate how to temporarily connect a pair of headphones to the audio output channels of the Qwiic Tsunami with the IC hook cables. Connect the TRRS 3.5mm jack breakout board to the Qwiic Tsunami, as illustrated below:

  • Connect three of the IC hook cables to the TIP, RING1, and SLEEVE pins on the TRRS headphone jack breakout board.

Below, is a table summarizing the cable connections between the Qwiic Tsunami's pins and the TRRS 3.5mm jack breakout board's pins:

Cable 1 1L TIP
Cable 2 1R RING1

Finally, users will need to connect their headphones to the TRRS 3.5mm jack breakout board. The overall hardware assembly should resemble the image below:

For a more permanent solution, users can solder the boards together with hook-up wire.

Assembly for Arduino (Qwiic) Example

The assembly for the example in the Arduino library section is similar to the previous assembly. Users only need to connect their RedBoard Plus to the Qwiic Tsunami with a Qwiic cable. The RedBoard Plus should also be connected to their computer with a USB cable.

Users interested in connecting the Qwiic Tsunami to other MIDI devices will need to solder the MIDI pins to a 5-pin DIN connector. For more information, users can check out the original Tsunami hookup guide, our MIDI tutorial, and the Tsunami user guide under "MIDI Implementation.
