I was trying to calculate analog voltage in nrf51822 through ADC.
I used analog 2 pin
ref voltage =1.2v
pre scaler = 1/3
so while i connected 0.9v to analog pin.
I see...
In the sensor datasheet it says one can use SPI_Mode 0 or 3 (doesn't say that there is anything to do to switch between them).
I connected MISO from the DK with SDO from...
