Twi interface

[yashchabria]

Which is the preferred way,  accessing sensor via the TWI

1) NRFX_Driver

2) TWI HAL 

what options do I need to select in the SDK_CONFIG.h to use the twi_driver api.

Also, what does this imply  'NRF_DRV_TWI_INSTANCE_0' was not declared , I have enabled TWI in sdk_config.h

I sorted the 'NRF_DRV_TWI_INSTANCE_0' issue with sdk_config.h
