Raspberry Pi I2C & GPIO driver install & Setting.

Raspberry Pi I2C & GPIO driver install & Setting.
1.Make sure your I2C driver are enable
To enable it all you need to do is comment out a line by putting # in front
sudo nano /etc/modprobe.d/raspi-blacklist.conf

 

 

2. Add i2c-dev  in /etc/modules  by use

sudo nano /etc/modules

 

3.  Next install the  python-smbus python module:

sudo apt-get install python-smbus 

sudo apt-get install i2c-tools

 

Now you are ready to use the i2c with python.

 

If you already install I2c driver ,

     i2cdetect -y 0        -  for Raspberry Pi V1 Board

 

 

  i2cdetect -y 1        -  for Raspberry Pi V2 Board
