Root Cause

ADC reading incorrect due to noise, reference, or config.

generic

Workarounds

  1. 88% success Add hardware filtering: capacitor on analog input, proper Vref
  2. 85% success Configure adequate sampling time and use oversampling

Dead Ends

Common approaches that don't work:

  1. Filter readings by removing outliers 72% fail

    Loses real spikes

  2. Use maximum ADC clock speed 78% fail

    Increases noise, lower accuracy
