In order to prevent the influence of the deviation of AVCC during ADC conversion, the internal reference voltage (Vref) of ADC is fixed to 2.816V even it derives from AVCC. Modified sources: 1. wheatley/board.c: Modified max adc voltage of ADC to 28.160V. 2. adc_chip.h: Modified internal ref voltage of ADC to 2.816V.
