HATIRE HEADTRACK (a little guide)

I write this guide to help anyone to use hathire in any sim/game. Let’s start with hw and sw requirements.

HARDWARE:

1. a MPU9250 device preferring a 5V tolerant device, i did not test a 9255;

Mpu9250

2. an arduino board, you can choose any kind but if your MPU works at 3.3V, you need a board with a 3.3V pin. I use this pro micro board 3.3V and 5V (it runs at 4.68V);

Pro-micro

3. a push button; 4. i used classic Dupont wires and some Dupont core plus and DuPont plastic shell plug chief.

Obviously this is not the only way to connect it, see http://edtracker.org.uk/ you could use a breadboard or a PCB. I use wires because i can disassemble it if needed.

SOFTWARE

WINDOWS:

1. install arduino IDE and drivers for your board;

2. connect your board and open device manager as amministrator→ ports (right click) → properties → port setting:

Win setup1

Win setup2

LINUX:

1. download the arduino IDE, unpack somewhere;

2. connect your arduino, open a terminal and type: “lsusb”. You get something like this: “Bus 003 Device 008: ID 2341:8037 Arduino SA Arduino Micro”. Yours will be different;

3. as root create a file in “/etc/udev/rules.d”. Call it “52-arduino.rules”, inside put:

 SUBSYSTEM=="usb", ATTR{idVendor}=="2341", ATTR{idProduct}=="8037", MODE="0666", GROUP="plugdev", SYMLINK+="arduino arduino_micro"

4. IdVendor and idProduct could be different for your board.

5. Restart udev as root with “service udev restart”;

TRICKS:you could have problem flashing the code on board try, while you press load, to reset the board connecting for a while RST with GND (windows and linux), remove modemmanager (linux). Perhaps if arduino IDE doesn’t start you need to make the main binary executable with “chmod +x /path/filename”(linux).
