go-tsunami

Sparkfun Tsunami serial control library for golang

Tsunami is a polyphonic Wav file player with 4 stereo (or 8 mono) outputs. Wav files can be triggered using the 16 onboard contacts, via MIDI, serial connection or Qwiic to a PC or other microcontroller.

This library is a manual transpilation from the official library Tsunami-Arduino-Serial-Library.

Installation

The recommended way to install go-tsunami

go get github.com/mcuadros/go-tsunami

Example

ts, err := tsunami.NewTsunami("/dev/ttyUSB0")
if err != nil {
	panic(err)
}

defer ts.Close()

if err := ts.Start(); err != nil {
	panic(err)
}

trackNum := 1

ts.TrackGain(trackNum, -70)                     // muted
ts.TrackPlaySolo(trackNum, 0, false)            // track = 19 (aka "19.WAV"), output = 0 (aka "1L")
ts.TrackFade(trackNum, 0, time.Second*5, false) // track 19, fade to gain of 0,
// fade time = 5000ms, stopFlag is false = do not stop

fmt.Println("Fading IN track 19 right now...")
time.Sleep(time.Second * 5)

fmt.Println("Gain set to unity (0)! Playing for 5 seconds...")
time.Sleep(time.Second * 5)

ts.TrackFade(trackNum, -70, time.Second*5, true) // track 3, fade to gain of -70,
// fade time = 5000ms, stopFlag is true = stop track when fade is done

fmt.Println("Fading OUT track 19 right now...")
time.Sleep(time.Second * 5)

fmt.Println("Track 19 stopped.")
