nrf52832 TWI Read and Write

[Sushi_27]

Hi there,

I'm developing with the nRF52832 right now.

I want to communicate nrf52832 (as master) with MP2723 to read and write  data  with TWI.

If you are unfamiliar with I2C or NCS and not sure how to get started, I would recommend having a look at the Nordic DevAcademy:

Thanks for the references. 

I'm able to communicate with the slave.

Sorry for late response. 

The problem is that slave register's  value is changed  after writing to it. I don't know that I should write it again or what should be done to get back to the default value. 

( slave register with address 0x00 had default value 0x48. But now its showing 0x00 )

I don't understand, is this not expected?
