Easy IMU Python Library

This library helps communicate with the already setup Easy IMU Module (i.e MPU9250 EIMU Module) in your PC or microcomputer-based python projects, with the eimu_setup_application.

you can use it in your microcomputer robotics project (e.g Raspberry Pi, PC, etc.)

A simple way to get started is simply to try out and follow the example code

Dependencies

• you'll need to pip install the pyserial library

    pip3 install pyserial   //linux or mac
    pip install pyserial   //windows

How to Use the Library

• Download (by clicking on the green Code button above) or clone the repo into your PC using git clone

Note

you can use this command if you want to clone the repo:

git clone https://github.com/samuko-things-company/eimu_python.git

• Ensure you have the Easy IMU Module is already calibrated.

• Connect the Easy IMU Module to your PC or microcomputer

• A simple way to get started is simply to try out and follow the example read_rpy.py code.

• You can copy the eimu.py file into your python robotics project, import the library as shown in the example read_rpy.py code, add it to your code, and start using it.
