configure_i2c();

1. 1.1.
   Create and initialize configuration structure.

   struct i2c_master_config config_i2c_master;
   i2c_master_get_config_defaults(&config_i2c_master);
   

2. 1.2.
   Change settings in the configuration.

   config_i2c_master.buffer_timeout = 65535;
   

3. 1.3.
   Initialize the module with the set configurations.

   while(i2c_master_init(&i2c_master_instance, CONF_I2C_MASTER_MODULE, &config_i2c_master)     \
           != STATUS_OK);
   

4. 1.4.
   Enable the module.

   i2c_master_enable(&i2c_master_instance);
   

configure_i2c_callbacks();

1. 2.1.
   Register write complete callback.

   i2c_master_register_callback(&i2c_master_instance, i2c_write_complete_callback,
           I2C_MASTER_CALLBACK_WRITE_COMPLETE);
   

2. 2.2.
   Enable write complete callback.

   i2c_master_enable_callback(&i2c_master_instance,
           I2C_MASTER_CALLBACK_WRITE_COMPLETE);
   

wr_packet.address     = SLAVE_ADDRESS;
wr_packet.data_length = DATA_LENGTH;
wr_packet.data        = wr_buffer;
