Python application to read data from MPU 9250 sensor through the Arduino's serial port and display it with matplotlib

Introduction

This python application can be used to process the data read by mpu9250-arduino and display the sensor data using matplotlib.

Install dependencies

Make sure you have the following installed:

• python 3.x
• virtualenv

Execute these commands to run the application:

> virtualenv env
> source ./env/bin/activate
> pip install -r requirements.txt

Run the application

The command is: python main.py -d <device_id> -b <data_rate> -o <test_csv_file>

Where:

• device_id is the name of the serial port on which the arduino is connected. The easiest way to find it out is to launch the Arduino IDE and in the you search for it Tools -> Port menu, it will be something like /dev/cu.usbmodem14411 on a Mac.
• baud_rate is the data rate used to communicate on the serial port
• test_csv_file is the filename of a file to write data to (this parameter is optional).

Examples:

# Basic example
> python main.py -d /dev/cu.usbmodem14411

# Specify different data rate (the default is 115200)
> python main.py -d /dev/cu.usbmodem14411 -b 9600

# Specify an output file
> python main.py -d /dev/cu.usbmodem14411 -o data.csv
