Expected result
  ===============
  When running this test, you should see the samples of all configured ADC lines
  continuously streamed to std-out.
  
  Background
  ==========
  This test application will initialize each configured ADC lines to sample with
  10-bit accuracy. Once configured the application will continuously convert each
  available channel and print the conversion results to std-out.
  
  For verification of the output connect the ADC pins to known voltage levels
  and compare the output.
