InvenSense Developers Conference 2016 - SensorStudio & development platform simplifies and reduces software and algorithm development cycle, time to market and enable developers to go from C-to-Reality in minutes. Join this session to understand how, thru a concrete use case. https://www.invensense.com/sensorstudio/ https://www.invensense.com/products/genericsensorhub-development-kit/ https://www.invensense.com/products/firefly-development-kit/

2. SensorStudio
With ICM-30670

3. Joke of the day 
• Wondering how we created a PingPong demo?

InvenSense Developers Conference 20163

4. Foreword
• “And we’ve analyzed over 700 swimmers, different body
types, different abilities. We hooked them up to state-of-the-
art metabolic equipment. We’ve even drawn blood samples
to look at lactic acid levels and we used all this body of
information to create an algorithm that will give you the
most accurate calorie burn information while you’re
swimming. ”

5. Agenda
• Why
• What
• How: Hardware
• How: Software
• Demo
InvenSense Developers Conference 20165

6. Why
• Bring a “WOW factor” @ IDC’2016
• Inspire you to create great sport applications
Using SensorStudio & ICM-30670 Dev Kit
InvenSense Developers Conference 20166

7. What
• Piezzo+ADC
– Raw signals (used for ball impact)
• FireFly ICM-30670
– Fusion Piezzo & IMU
– Ball impact detection
• SensorStudio
– Design/Debug/Demo
InvenSense Developers Conference 20167

8. How: Hardware BOM

https://www.invensense.com/products/motion-tracking/6-axis/firefly-development-kit/
• Arduino Zero - https://www.arduino.cc/en/Main/ArduinoBoardZero
• Adafruit ADC - https://www.adafruit.com/products/1083
• Piezzo - https://www.arrow.com/en/products/7bb-12-9/murata-manufacturing
InvenSense Developers Conference 20168

9. How: Hardware Schematic
InvenSense Developers Conference 20169
Arduino Zero
Battery
Adafruit ADC
SPI
Cortex M0
I2CPower
SensorStudio ICM-30670 Dev Kit
FireFly ICM-30670

10. How: Hardware DevKit adaptations
• Connect ICM-30670 DevKit to
ADC
– Power, I2C
• Use double sided foam strip with
adhesives on both sides
InvenSense Developers Conference 201610

11. How: Hardware Racket adaptations
• Cut & glue the Piezzo buzzer on the racket
– Conserve ability to respond to applied mechanical stress
• Connect ADC to Piezzo
– Make it easy to plug in/out
InvenSense Developers Conference 201611

12. How: Humanoid hack 
• Got to pay the price, so science can advance!
– Elastic band strap with velcro is your friend
• Connect
– Piezzo to ADC
– Arduino zero to PC (tie the cable to your body)
InvenSense Developers Conference 201612

13. How: Software SensorStudio
• SensorStudio used to create Piezzo/ADC driver
(AuxiliarySensor)
• SensorStudio used to create algorithm (CustomSensor)
• Visualization of sensors & algorithm outputs
InvenSense Developers Conference 201613

14. Reference: Add a driver
• Task & notify pattern to produce sensor data
InvenSense Developers Conference 201614

15. How: Software Piezzo/ADC driver
• Configure the I2C
• Initialize ADC, set its range to 256mV
• Starts the acquisition task
– notify sensor hub of the new piezo data
InvenSense Developers Conference 201615

16. How: Software low level driver
• All come down to read/write on I2C
InvenSense Developers Conference 201616

17. How: Software desktop run
• Ball impact detection algorithm need ADC/Piezzo driver
• Build & Flash
• Outputs: int16 (Shot)
InvenSense Developers Conference 201617

18. Reference: Add an algorithm
• notify & subscribe pattern to consume/produce
sensor data
InvenSense Developers Conference 201618

19. How: Software ball impact detection
• Principle: Simple Piezzo threshold over time
InvenSense Developers Conference 201619

20. How: Software helper
• Principle: Rotate gyro to hearth reference frame
InvenSense Developers Conference 201620

21. How: Software Fore/Back hand
detection
• Principle: Rotation sign around gravity vector
InvenSense Developers Conference 201621

22. How: Software embedded run
• Build & Flash Shot Classification algorithm
• Outputs: int[3] (Stroke number, Power, Effect)
InvenSense Developers Conference 201622

23. How: Software test
• You can observe all the algorithm ouputs
InvenSense Developers Conference 201623

24. How: Software – Arduino init FireFly
• Load&start FireFly
InvenSense Developers Conference 201624

25. How: Software – Arduino sensor event
• Get Ping Pong data from FireFly ICM-30670 
InvenSense Developers Conference 201625

26. And now?
