SAKURA Internet
Example code of sakura.io Evaluation board.
Dependencies: AQM0802A BME280 MPU9250_SPI SakuraIO gps mbed
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`
