SerialTracker

Alternative firmware code for the Relativty head tracker that uses the MPU6050 (or MPU9150) sensor.

Getting started

Arduino Due (and Uno) boards haven't been tested yet, I don't own a Due so it's up to you.

Hardware

Connect the sensor corresponding to the defines in the SerialTracker.ino sketch, here are the defaults:

Sensor	INT	SDA	SCL	VCC	GND
Board	INT_PIN	SDA_PIN	SCL_PIN	VCC_PIN
Due	2	20	21	5	GND
STM32	PA1	PB6	PB7	PB5	G
ESP32	IO17	IO18	IO19	IO5	GND
Uno	2	A4	A5	5	GND

Software

1. Install Arduino IDE
2. Install Arduino IDE support for your board:
   • Arduino Due: Getting started with the Arduino Due
   • STM32 Pills: Arduino for STM32
   • ESP32: Arduino core for ESP32 WiFi chip
3. Install additional libraries for Arduino IDE
   • I2CDevLib, for installation simply copy the I2Cdev, MPU6050 and MPU9150 folders (below the Arduino folder in the archive) to your Arduino/libraries directory.
4. Put the folder containing this README.md (and SerialTracker.ino) in your Arduino directory.
5. Start Arduino IDE, open sketch and upload.
