SakuraIo Evaluation Board Standard

Overview

This program is example code of sakura.io Evaluation board.

Functions

  • Periodic measure from onboard sensors(period is 200ms)
    • Motion sensor(gyro, accelometer, magnetometer)
    • Environment sensor(temperatur, humidity, airpressur)
    • GPS(longitude, latitude, timestamp)
  • Periodic send the measuring datas to sakura.io platform(period is 300sec)
  • Output the measured datas output to USB-Serial port
    • baudrate is 9600bps
  • Can select on / off of periodic running with switch `SW5`
