Normally the ADC channels are converted each mS from the programming model (main.c) - optionally this can be skipped with define MIOS32_DONT_SERVICE_AIN 1 in mios32_config.h

In this case, the MIOS32_AIN_StartConversions() function has to be called periodically from the application (e.g. from a timer), and conversion values can be retrieved with MIOS32_AIN_PinGet()
