Interfacing ADIS16364 with Arduino
====================================
This software package is an example of how to interface an ADIS16364 iSensor with an Arduino Mega 2560.

What you'll need
----------------
- Arduino Uno, or Arduino Mega 2560
- ADIS16364 with breakout board
- Jumper wires
- Arduino IDE
- Python with modules below, I tested this on Python 2.7
    + pySerial python module, see http://pyserial.sourceforge.net/
    + NumPy python module, see http://numpy.scipy.org/ 
    + SciPy python module, see http://www.scipy.org/
    + matplotlib python module, see http://matplotlib.sourceforge.net/

Connections
------------
Using jumper wires, make connections from the ADIS16364 breakout board to the Arduino
as shown below:

Arduino Uno Connections 
-----------------------------
CS   (J1-3)  - to digital pin 10 (SS)
SCLK (J1-2)  - to digital pin 13 (SCK)
DOUT (J1-4)  - to digital pin 12 (MISO)
DIN  (J1-6)  - to digital pin 11 (MOSI)
VCC  (J1-12) - to 5V
GND  (J1-9)  - to GND 

Arduino Mega 2560 Connections 
-----------------------------
CS   (J1-3)  - to digital pin 53 (SS)
SCLK (J1-2)  - to digital pin 52 (SCK)
DOUT (J1-4)  - to digital pin 50 (MISO)
DIN  (J1-6)  - to digital pin 51 (MOSI)
VCC  (J1-12) - to 5V
GND  (J1-9)  - to GND 

See ADIS16364 datasheet Rev D, Figure 18, pg 17 for illustration of J1 and J2 connectors


How to use 
----------
Once you've installed everything above, and made all the proper connections, it's time to
program the Arduino. First open up the ADIS164364.ino file with the Arduino IDE. 
Press verify, and upload (after which you have properly setup the IDE with serial port, and device).
Now close the IDE, because you may have issues with the python plotting if you have both 
programs trying to access the same serial port.

Plotting data with Python
-------------------------
usage: plot_data.py [-h] -p PORT -r RATE [-b] [-n NUM] [-s]

optional arguments:
  -h, --help            show this help message and exit
  -p PORT, --port PORT  Serial port, ie /dev/ttyACMX on Linux, or COMX on Windows
  -r RATE, --rate RATE  Baud rate
  -b, --bar             Show Bargraphs Instead of line plots
  -n NUM, --num NUM     Window width, default is 100 points
  -s, --smooth          Make lines look smoother


To run on Windows:

python plot_data.py -p COMX -r 9600

To run on Linux:

python plot_data.py -p /dev/ttyACMX -r 9600  

if you don't have udev setup for your Arduino, and you get permission issues, try running it as root:

sudo python plot_data.py -p /dev/ttyACMX -r 9600
