Commands in User Space

Linux provides some useful I2C related commands in the file system helping us control I2C bus.

The following code blocks provide some simple examples.

To detect all the registered I2C adapters:
```
i2cdetect -l 
```
To detect all the client devices mounted on the specified I2C adapter:
```
i2cdetect -y -r [i2c_adpter_index]
```

To read the address from the specified I2C client:

i2cget -y [i2c_adpter_index] [i2c_client address] [address]

To write the address to the specified I2C client:

i2cset -y [i2c_adpter_index] [i2c_client address] [address] [value]
