Hi,
I had this problem too.
It was because i did not provide the AdcConfigure interface.
Your app should provide this interface by implementing its
getConfiguration() command.
command adc_config_t getConfiguration()
{
return &config;
}
Otherwise you get 0xff's as data in the dataready events.
Cheers,
O.Chougna
