IMPLEMENTATION OF THE PROJECT

For running the project we need to go through some process. Process are given below.

Wiring the connection

MPU9255              STM32F4Z9I-DISCO Board
 SCL ----------------------------- PB10

 SDA ----------------------------  PB11

 INTA ---------------------------  PB1
 VCC ---------------------------   5V

 GND --------------------------- GND

USB TO TTL BOARD                     STM32F4Z9I-DISCO Board 

 TX ----------------------------------------------- PA9
 RX ----------------------------------------------  PA10

​

Setup the CoCox IDE.I prefer to download the version of 1.7.8. In the newer version, there have some library and feature missing which is required for the project.

Open the Project

Change the configuration according to below picture

Rebuild all. Hopefully, there should not have any error
Connect the hardware and download the hex file to the hardware
Python Client

A Python client is included with the release package to test the performance and display log information. The client can be found in the release package under the directory (..\eMPL-pythonclient). The python client also accepts user input and provides the input the sample HAL Application. The user would be able to enable/disable sensors, enable computation algorithms, enable hardware features, and view log information. You would need to install Python (version 2.5 and above), pyserial and pygame for the python script to execute.

Installing Python 2.7 (32-bits version) or above, pyserial, and pygame

Python: https://www.python.org/downloads/
Pyserial: https://pypi.python.org/pypi/pyserial

Pygame: http://www.pygame.org/download.shtml

Connect your flashed and working hardware to your PC and find the COM port in the device manager if the connected device. You should find out the no of COM port.
Installing Python 2.7 (32-bits version) or above, pyserial, and pygame

python eMPL-client.py <COM PORT NUMBER>
Ex: python eMPL-client.py COM3

2 Windows will pop one. 1 contains a 3D Cube which corresponds with the quaternion angles outputted from the device. The other window will display any related logs or data.
Motion Driver can accept input commands and display various different data. You must first make sure the cube window is the focused window then type in the input command.

  23.  ‘5’ : Change sensor output data rate to 100Hz

  24.  ‘,’ : set interrupts to DMP gestures only

  25.  ‘.’ : set interrupts to DMP data ready

  26.  ‘6’ : Print Pedometer data

  27.  ‘7’ : Reset Pedometer data

  28.  ‘f’ : Toggle DMP on/off

  29.  ‘m’ : Enter Low Power Interrupt Mode
