6.1.6 LED Control Library Usage
1. User needs to include the header file <led_control.h> of the library into the application source
code.
2. User needs to initialize the library by calling the LEDInit() function.
[Once Init is successful, multiple APIs can be called before deinit.]
3. Call the relevant API from following list in LED Control Interface Table to perform operation on
LED I2C interface.
4. De-initialize the library by calling the LEDDeInit().
5. Link the library while compiling the application by “-lledinterface”.

6.1.7 Common Interface Library Usage
1. User needs to include the header file of the library into the application. For Common interface,
It will be <common_i2c_operation.h> file.
2. Call the relevant API from following list in Common Interface Table to perform operation on I2C
interface. This functions expects different arguments. common_i2c_operation.h describes all
functions operations, input & output parameters.
