I need to get three ADC data from acceleration sensor with nrf51822. I tested getting a ADC data using simple_adc_pca10028(Keil_v5/ARM/Pack/NordicSemiconductor/nRF_Examples/11.0.0-2alpha/peripheral/adc_simple) example. But I don't know how to get multi ADC data, except for exchange pin select constantly. I also saw this source, but I failed to run it, despite of removing and adding libraries and drivers and reconfiguring input path.
