Hey,
I am trying to run F8100 development board with nrf52840 development board, while I make the connection simply like CS-D10(Arduino pin layout presenting), MISO- D11, MOSI- D12, SCK - D13 and INT - D2 . PD i am not sure so tried D4 because in Arduino development they use in it. So when I made connection I don't see any light or anything on it. So anyone know how to start with the hardware connection
