Integrating your IoT boards with ReSpeaker

ReSpeaker is built with Arduino (ATmega32U4) and Linux-based OpenWrt with MCU MT7688 so that we can access GPIO pins in our program. We can develop a sketch program for the ReSpeaker board. Start by downloading the ReSpeaker library for Arduino from https://github.com/respeaker/respeaker_arduino_library. Download and extract it to the Arduino library with the name respeaker.

Now you can use the ReSpeaker library in your Arduino IDE. For testing, we'll try to access 12 RGB LEDs using the pixels library.

First, you should install Arduino software from this site: https://www.arduino.cc/en/Main/Software. Then, you can write the following sketch program:

#include "respeaker.h" 
 
uint8_t offset = 0; 
void setup() { 
  respeaker.begin(); 
  // set brightness level (from 0 to 255) 
  respeaker.pixels().set_brightness(128);   ...
