#mpu6050 python3

I had been planning to use this MPU with the Nano I bought, however after having a blast playing with the kids on RPi2, I wanted to connect this I2C component to the I2C capable RPi2. How hard could it be?

Not hard as it turns out. The hardest part is getting used to Terminal.

Software install

Somewhere through the process, I found this guide, partly copied here in case something happened. There are pictures of the wiring too.

In the case of a RPi2, assuming you fixed python3 as in my previous post ‘Raspberry Pi 2 for the kids’ , I believe that the following should be avoided:

> sudo apt-get install python-smbus > sudo apt-get install i2c-tools

The following config file needs editing on with the ‘nano’ editor.

> sudo nano /etc/modules

You will need to add the following lines at the end:

snd-bcm2835 i2c-dev

On RPi2 I did not have issues with blacklisting.

I later found out that I had to reconfigure the board to enable I2C bus 1

Done via 

> sudo raspi-config 

then go to 

Advanced Options ->  I2C enabled <yes> -> I2c module loaded by default <yes>

Then reboot

> sudo reboot

Hardware install and identification

I soldered the pins that came with the MPU6050 in order to be able to insert it on the bread board.

After wiring, I saw a red light on the MPU6050 board, a good sign!

It was time to try and identify if anyone was detected on the I2C bus via:

> sudo i2cdetect -y 1

The result was positive for '68' , which is in hexadecimal for the address of MPU.

0x68 = 104

You can hard wire MPU6050 to respond on 0x69, if you wanted something else on 0x68.

Using MPU6050

At that point you can find the manuals for its I2C interface on the web, and/or find a partial driver in Python3 like I wanted to do
