Hi guys,
I am trying to interface nrf52832 with PMIC(BQ25121). I have earlier interfaced PMIC with nrf52832 successfully, and I am using the same code. However this time, I am getting NRF_TWI_ERROR_ADDRESS_NACK error.
I have looked over the error, and verified that my pin mappings are correct.
I could check for the scl/sda voltage levels in logic analyser, however I can't take scl/sda lines, as mine is a custom board.
Could anyone suggest any other possible causes and means to rectify this error....
