ReSpeaker Arduino Library

Features

• supported capacitive touch sensing
• implemented WS2812 RGB LED driver
• built USB to Serial bridge and SPI bridge between Arduino (ATmega32U4) and linux based OpenWrt (MT7688)

Requirements

• Arduino IDE 1.6.8+. Please use Arduino IDE 1.6.8+ which has some useful new features

Installation

1. Download zip file and extract it into Arduino's libraries directory.
2. Rename respeaker_arduino_library-master to respeaker

Getting Started

1. Light - chasing colors

#include "respeaker.h"

uint8_t offset = 0;

void setup() {
  respeaker.begin();
  respeaker.pixels().set_brightness(128);      // set brightness level (from 0 to 255)
}

void loop() {
  respeaker.pixels().rainbow(offset++);
  delay(10);
}

2. Touch & Sound - touch to play

#include "respeaker.h"

// wav or mp3 files on SD card
const char *sound_map[] = {"a1.wav", "b1.wav", "c1.wav", "d1.wav", "e1.wav", "f1.wav", "g1.wav", "c2.wav"};

void setup() {
  respeaker.begin();
  respeaker.attach_touch_handler(touch_event);  // add touch event handler
}
void loop() {}

// id: 0 ~ 7 - touch sensor id; event: 1 - touch, 0 - release
void touch_event(uint8_t id, uint8_t event) {
  if (event) {
    respeaker.play(sound_map[id]);
  }
}

3. connect to IFTTT maker channel

#include "respeaker.h"

#define IFTTT_MAKER_CHANNEL_KEY ""              // add the key of your ifttt maker channel
#define EVENT                   "ping"

const char *ifttt_ping = "curl -X POST https://maker.ifttt.com/trigger/" EVENT "/with/key/" IFTTT_MAKER_CHANNEL_KEY;

void setup() {
  respeaker.begin();
  respeaker.attach_touch_handler(touch_event);  // add touch event handler
}
void loop() {}

// id: 0 ~ 7 - touch sensor id; event: 1 - touch, 0 - release
void touch_event(uint8_t id, uint8_t event) {
  if (event == 1 && id == 0) {
    respeaker.exec(ifttt_ping);
  }
}
